Laptops are getting sophisticated, faster, lighter. The one thing still trailing behind is the battery. Following are things you can do on your laptop to conserve power and extend its laptop battery life.

Power Scheme Mode - -

Selecting the right ¡°power scheme¡± will help to prolong the life of laptop battery. Use the ¡°Low Power Mode¡± since it will not consume more power than ¡°Max Power Mode¡± battery.

To adjust battery setting: Start > Control Panel > Performance and Maintenance. Click on the ¡°Power Options¡± icon. The power setting window will appear, make your settings from there on.

- - Stop Background Programs - -

Pressing the Ctrl + Alt + Delete simultaneously to bring up the Task Manager. Under the first tab (Applications), you can see all the current ¡°open¡± programs that are running on your laptop, try to close the background from your dell GD761 battery.

Click the Process tab, next to the Applications. You will see all the real-time processing items on your laptop, kill those that you are not using. All the unused programs but are running will increase the CPU usage, which in turn will cause a lots of wasting power. You can determine which ones to disable by reading the titles on the processing list.

- - Screen Brightness - -

Control the brightness of the screen according to your environment. dell TD347 batteryscreen use plenty of power, too.

- - Disk Defragment - -

Hard disk is a big consumer of electricity. The more efficient the hard disk the less power it use. To minimize read-write head movement, defrag your hard disk regularly. If you use your  Dell Latitude D620 battery all the time, do it once every 2 or 3 months. All hard disks should be defragged at least once each year, regardless a laptop or desktop.

To defrag: Start > Performance and Maintenance. On the list under the title ¡°Pick a task¡­¡±, first, select ¡°Back up your data¡±. Then come back to the main menu and choose either ¡°Free up space on your hard disk¡±, or ¡°Rearrange items on your hard disk to make programs run faster¡±. The latter is recommended. Follow the steps to complete process.

- The Temperature Factor - -

Your Dell Inspiron E1505 battery will operate more efficient when temperature is cool. Make sure the vents are not blocked.

- - Avoid Multitask - -

Try to work on one thing at a time and close unnecessary windows or applications. You might be tempted to work and finish many projects at once, but this will also drain your Dell Inspiron 1525 battery faster, and you may run out of battery before you complete your work. You are also using power when typing, using mouse or touch pad - they are all electric signals, same with the plugged USB ports.

- - Disable Wireless Signal - -

WiFi sip a lot of juice from the battery. Turn off the wireless signal if you are not using, you will save up to 30 minutes of power.

- - Storing Battery - -

Charged battery unused for a long time would deteriorate it. Keeping a spare camcorder battery is not recommended because lithium-ion batteries need to be ¡°exercised¡±. Only buy new battery when you know that your current one (in use) is about to expire. Once charged, a battery should slowly be used. Frequent charge and drain will shorten laptop battery lifespan.

- - Hibernate, not Stand-by - -

If you want to start up your laptop faster, use Hibernate mode as that would save the last state of your system, it will then shut down the entire power to the laptop. Stand-by only lowers power consumption as safty code is camera battery.

All desktop and laptop battery  computers use a special battery called a Complementary Metal Oxide Semiconductor (CMOS) battery which stores information about your computer, such as the date and time, when the machine is powered off. Normally the battery re-charges itself whenever the computer is turned on but if it stops working or becomes damaged you will need to replace it manually.

Unplug the power cord camcorder battery  from the power supply on the back of your computer. Remove all of the extra cables for the mouse, keyboard, monitor, printer and speakers.

Use a screwdriver to unscrew the case screws on the side of your computer. Put pressure on the side panel and slide it off the case

Locate the small circular sony laptop battery, which will usually be either color or silver-colored, near the center of the motherboard. Check the model number on the top of the battery and then purchase a replacement through an online electronics store or a local computer supply store. Make a note of the model information on the battery as you may need it to complete the installation.

Snap off the battery cover if your motherboard has one and then remove the CMOS dell Inspiron 6400 battery by simply pulling it out of its holder.

Push the replacement battery back into the battery slot and pop the cover back down. Put the side panel back on the case, re-attach all of the cables, and then power on your computer to ensure the dell Inspiron 6000 battery was correctly installed. Wait to see if the computer changes to a prompt asking for the battery information or if it boots directly to the desktop.

Enter in the digital camera battery model information you wrote down earlier if the prompt asks for it and then hit ¡°enter¡± to finish the installation.

BYD electric cars on the industrialization of preparing the same time, the outside world BYD battery patents challenged once again been filed. Regard to some people, BYD sales company vice president Wang are to respond, "BYD has a patent-iron battery applications, including iron battery performance, structure, etc. are applied for a patent." 

 
"As you can see, and the general public's cooperation is also revealed by the mass first, since we are new, or to say that this was the vehicle factory, and we want to be someone that likes Bang Dakuan BYD." Wang expressed. "You only know that the water drink is a patent application, but this water, after adding a certain Dell Latitude D630 battery, Dell Latitude D820 battery component, as well as other purposes, is not the monopoly, while BYD now is to have water, the application of the patent." According to Wang said, BYD has intellectual property rights, there are several thousand patent engineer. "Frankly speaking, both are connected to each computer patent databases, all of these matters that we have estimates of." 

 
June 12, vice president of BYD Group, the summer ice rule himself confirmed to this newspaper, in addition to Germany before the public, BYD has also ranked the first three of a domestic Automotive Group entered into a memorandum of understanding with iron batteries. 

 
There are many automobile companies at home and abroad have come into contact with BYD, BYD in Shenzhen Ping Shan in the office building, please come to a certain company BYD's LCD screen constantly changing content, June 11 day, Matsushita, and so companies will have to visit. 

 
To industry sources, the international community on the iron dell Inspiron 1100 battery, Dell Inspiron 1300 battery, that is, lithium iron phosphate batteries, in the basic materials, the composition of the existence of the dispute, because BYD does not have the basic materials of the patent, so production will be referred to later as part of the patent fees, which will lead directly to the battery cost increase.

Japan Institute of Industrial Science and Technology (JST) and the Institute of Chemistry, Tanaka (Headquarters: Fukui City) co-developed a non-cobalt oxide lithium-ion rechargeable battery cathode materials. Non-metals cobalt, iron low transition metal content of the total 20%. Discharge voltage of 3.5 ~ 3.7V, compared with production Soken previously developed oxide cathode materials (discharge voltage of 3.0V) has been greatly improved, close to the existing cathode materials, discharge voltage 4.0V. Is expected to make full use of previously difficult for us to import iron oxide cathode materials. Contribute to the achievement of the materials as electric vehicles and hybrid lithium-ion rechargeable batteries and other energy-saving technology and low cost of the toshiba PA3285U-2BRS battery,toshiba PA3285U-3BRS battery materials is expected.

To popularize lithium-ion rechargeable batteries, not only to ensure safety performance, but also the need to achieve high performance and low-cost technology. In particular, in order to achieve low-cost, need to adopt low-priced products as cathode, anode and electrolyte and other materials. Of these, lithium transition metal oxide cathode material for use more rare metals, cobalt price of the battery constitutes a material, one of the most expensive material. Therefore, the production & Research Institute has been able to develop low-cost and resource-rich cobalt metal alternative technologies, these metals, including control of existing lithium-ion rechargeable battery performance degradation, and the price of cobalt is only 1 / 10 of iron, only the cobalt 1 / 8 of around cobalt manganese and only about 1 / 4 titanium and so on.

Production & Research Institute will be November 30, 2009 ~ December 2 at the Kyoto International Conference Hall's "the 50th Battery Symposium," published in the development of cathode materials for details. In addition, the results of this as a New Energy and Industrial Technology Development Organization of the commissioned research, "a new generation of high-performance vehicle toshiba PA3331U-1BAS battery,toshiba PA3331U-1BRS battery technology development of power-storage system (Li-EAD Project) - New low-cost high-capacity cathode materials of oxide Development (07 years to 09 years) "in a ring obtained.

According to the Japanese Economic and Trade Ministry of Industry sources said Wednesday disclosed, from the laptop battery beginning in January, Japan plans to resume the solar panel industry (the world's fifth-largest greenhouse gas emission reduction products) of all subsidies. 
   
Japan's Trade Ministry says it will be == the first quarter of 2009, funding 90 billion yen (99.6 million U.S. dollars) yuan for solar home outreach activities, from the April 2009 fiscal year began in an increase in their Dell Inspiron 1520 battery, Dell Inspiron 1525 battery, Dell Inspiron 1526 battery number may be . 
   
To achieve the 2050 greenhouse gas emissions reduction from the present 60-80% of the long-term goal, at present == efforts in 2020 to more than 70% of new homes to install solar panels.

In the (full) hybrid vehicles, the battery is the most expensive, but also the most delicate parts. Although the lithium battery with high power density advantages, but in the development of suitable DELL laptop battery for hybrid cars, there is still a lot to be done. In this case, the next few years, nickel-metal hydride (NiMH) batteries will still be more and more widely used.

     Hans-PeterHoenes pointed out that to achieve the fast charge without damage (damage) batteries, designers need a very precise charge (charge) control technology. Although the micro-controller integrated intelligent programming algorithm is basically a software solution, but Fairchild continued to focus on the dell Latitude D830 batterydell Latitude X300 battery hardware. In order to avoid interference with power lines during charging, a good power factor correction solution is necessary, to some extent even a legal norm requirement. The control IC Fairchild has an extensive product portfolio, combined with built-in with a soft-recovery rectifiers (performance of the rectifier diode) and low saturation voltage drop across the IGBT, can provide a complete solution.

     In the battery management, Cao Yu Li-ion battery that Infineon has a dynamic balance of Application patents, can reduce the differences between each other, effectively improve battery efficiency and longevity. This patented feature is the battery charged and discharged, or any idle time to implement power balance, very suitable for automotive power applications in such diverse environments and rapid mode switching needs.

     "In view of current technology, battery technology is the hybrid cars and electric cars key. Even a relatively high market appeal hybrid cars, batteries account for the cost of the vehicle's 1 / 3 or more. But also the weight of , reliability, longevity and many other issues to be resolved. lithium iron phosphate dell XPS M140 battery,dell XPS M1210 battery technology should be a better solution. However, as regards the above problems still need further improvement. Fuel cells are another technology, its technical maturity, fuels (mostly liquid hydrogen) storage and control issues, we can say can not immediately become a mature, mass-produced products. while pure electric cars, hybrid terms, the battery cost, weight, reliability, life , including the charging issue will be the government, automobile companies are facing a major problem. "Kang Xiao Dun said," So, the current hybrid vehicles in Europe and the United States and Japan, and has become industrialized, and domestic still in its infancy, there is no formation of industrialization. As the world's leading automotive semiconductor manufacturers, Freescale is committed to the Chinese domestic automotive electronics contribute to the development. Our key customer support (such as BYD, etc.), including technical exchanges, product pricing and so on. "

Rise Films

Over the past few years, the thin-film solar DELL laptop battery production in a high-speed increase.

According to market research firm DisplaySearch released on August 11 solar cell production capacity Trends Report, 2009 thin-film solar cell production capacity of approximately 3.58 million kilowatts.

The company's report also showed that thin-film solar cells in 2005 the total solar cell production capacity in about 5% by 2009 is expected to exceed 20%.

China Power Investment Group Co., Ltd. Xi'an solar electricity a technical staff of "Science News" explained: "By definition, that is, a layer of thin-film batteries into the solar cell thin films, because of its very small amount of silicon, it is easier to reduce costs."

The technical staff also said: "thin-film solar cell is a kind of energy-efficient products, but also easier to combine with the construction. Silicon raw materials in the international market against the backdrop of continued tension, thin-film solar cell has become the international PV market development trends and the new dell Latitude D505 battery,dell Latitude D510 battery  hot spot. "

At present, the thin-film solar cells include silicon-based thin-film solar cells, cadmium telluride thin-film solar cells, copper indium gallium selenide thin-film solar cells. Among them, the first solar energy company as the representative of the cadmium telluride thin film solar cell technology, the most common.

      In the thin-film solar cell market, the leader in the United States, Japan and other countries business. However, some Chinese enterprises in the thin-film solar cell production of solar cells in this emerging field not far behind.

September 9, located in Baoding Tianwei Paul changed the listed company issued a public notice saying that the company owned subsidiary of Tianwei film will invest more than 30 billion yuan to build an annual output of 150,000 kilowatts of two amorphous silicon thin film solar cell project .

More than two months ago, the emperor's annual output of 46.5 thousand kilowatts of thin-film amorphous silicon thin-film solar cell production line has been put into production, its initial photoelectric conversion efficiency of about 8%.

In addition to Tianwei, Best Solar, Suntech and other enterprises have also been or will be put into thin-film solar cell production lines. However, these enterprises are mostly thin-film solar cell production technology imported from abroad.

Promising thin-film solar cells, it does not mean no risk dell Latitude D520 battery,dell Latitude D600 battery.

China Electronics Materials Industry Association, Qing Li Yan told the "Science News", due to technical and cost factors, the next period of time, polycrystalline silicon solar cell industry will continue to be the main body.

"At present, thin-film solar cells solar cell industry in China, the proportion accounted for only about 10%. The next 10 years to 20 years, thin-film solar cells solar cells and will not occupy the dominant position, because its technology is not mature enough." He said: "Some thin-film solar cells, the relative efficiency of crystalline silicon solar cells behind, there are some good cost and high efficiency."

Worries nitrogen trifluoride

Thin-film solar cell industry in order to beat the competition in the future polysilicon solar cells, also have to face an environmental problem: thin-film solar cell production process in the release of nitrogen trifluoride has been considered a greenhouse gas.

In 2008, the University of California at Irvine Department of Earth System Science Michael Prasse (Michael Prather) and his colleagues in the "Journal of Geography of the Earth," published research papers, said nitrogen trifluoride to the greenhouse effect of carbon dioxide 17,000-fold. In the semiconductor, LCD panels and thin-film solar cell production process may be the release of nitrogen trifluoride.

Prasse told "Science News," a significant nitrogen trifluoride in the atmosphere of the greenhouse effect can exist 550 years or more pairs of infrared absorption capacity is also strong.

University of California, Scripps Institution of Oceanography Leiwei Si (Ray Weiss) and his research team also found that nitrogen trifluoride in the atmosphere of the concentration from 1978 to 0.02 / 1 trillion up to 2008's 0.454 / 10000 100 million.

Weiss said that although the current generated by human activities in the greenhouse effect, carbon dioxide accounted for 60%, only 0.04% of nitrogen trifluoride, but the proportion of nitrogen trifluoride may be growing exponentially dell Latitude D610 battery,dell Latitude D620 battery.

He told the "Science News": "Our monitoring results show that atmospheric emissions of nitrogen trifluoride higher than expected 4 to 5 times more."

At present, the "Kyoto Protocol" was concerned only with six kinds of gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. Prasse and Weiss suggested that the nitrogen trifluoride is also included in the need to reduce emissions of greenhouse gases out.

Weiss said: "We should reduce emissions of nitrogen trifluoride formulate corresponding incentives."

Atmospheric Composition Observation Service Center, China Meteorological Administration, said Liu Yu, nitrogen trifluoride produced by the greenhouse effect is indeed stronger than carbon dioxide, but the current global atmospheric levels of nitrogen trifluoride is not high.

Weiss also pointed out that the current nitrogen trifluoride emissions of only 0.04%, it will not be the worst greenhouse gases. Moreover, the majority of the use of clean technologies, whether it is thin-film solar cells or wind turbines, their production process will be accompanied by the production of greenhouse gases, as long as they are sufficient to cover the life of greenhouse gas emissions, then these new technologies is still useful.

For example, he said: "The thin-film solar panels over the life of number of decades, and they need only one or two years time on the production process can make up for the release of greenhouse gases."

Prasse said, semiconductors, LCD panels and thin-film solar panels could also consider alternatives to reduce their production of greenhouse gas emissions, is particularly important is that "must be a fair assessment dell Latitude D810 battery,dell Latitude D820 battery."

China is the world's largest solar DELL laptop battery manufacturing base. But for the Chinese solar cell companies are embarrassed that the Chinese government will build the world's largest solar power plant throws an olive branch to U.S. companies.

September 8, U.S. time, the Chinese government and the U.S. First Solar Inc. (First Solar) signed a memorandum, the two sides plan to Ordos in Inner Mongolia to build 2 million kilowatts of solar power plants. This will be the world's largest solar power plant, electricity for 3 million inhabitants.

Just two weeks ago, the Chinese government has solemnly stand polysilicon and solar cell industry, there is the phenomenon of redundant dell Inspiron E1505 battery,dell Inspiron E1705 battery construction. At this juncture, the Chinese government are also working with First Solar's high-profile launch Ordos solar plant project?

One reason may be because: First Solar's main attack is not a polycrystalline silicon solar cells. In fact, this company is a thin-film solar cell technology leader.

This super-large orders and also predict the future, thin-film solar cells in China and the world are expected to receive more applications.

Excess polysilicon

And the first Solar is different is that Chinese companies are basically production of polycrystalline silicon solar cells, its main raw material of polysilicon.

Compared with the thin-film solar cells, polycrystalline silicon solar cells photoelectric conversion efficiency. Thin-film solar cell is generally not more than 10%, while the polycrystalline silicon solar cells mostly in the more than 14%.

But the biggest advantage of thin-film solar cells is that you can not use expensive silicon, polycrystalline silicon solar cells is less than the required materials, energy consumption is also significantly lower than polycrystalline silicon solar cells.

Of course, the thin-film solar energy have a higher technical difficulty, is considered the next generation after the polysilicon solar cell solar dell Latitude D410 battery,dell Latitude D420 battery technology.

A few years ago, due to shortage of polysilicon material on the international market price of polysilicon as much as several hundred U.S. dollars per ton. In this context, the Chinese launched in many parts of the polysilicon production lines. A result, excess capacity, coupled with the financial crisis, the price of polysilicon followed sharp falls.

In the August 26 meeting of the State Council executive meeting on wind power and poly-silicon and other burgeoning industries considered to be "a duplication of the building tendencies."

The same day, the Ministry of Industry and Information Technology Zhu Hongren chief engineer in the Department also held a conference, said: "Solar energy, wind energy and other emerging industries redundant construction and disorderly launched the issue can not be ignored."

Meanwhile, the polysilicon production process of high energy consumption, as well as silicon tetrachloride and other toxic by-products pollution of the environment, has also been a lot of criticism.

As China's polycrystalline silicon solar cell products are mostly exported to developed countries, it was vividly called "consumption abroad, including pollution."

Polycrystalline silicon solar cell by the wake-up call at the occasion of solar cells, another member of the family - thin film solar dell Latitude D430 battery,dell Latitude D500 battery into the limelight.

The spate of fire incidents laptop let me chilling, since two months ago, a fire incident that occurred in Japan, lot of heated discussions, I will be afraid to use a laptop on the lap, but at home regard the DELL laptop battery unloaded. Remember that a friend told me that there is an English name laptop Laptop, meaning "laptops." The incidence of fire can not help but question: "laptop computer" on the laptop can also be used?

Because to do this topic, from the Internet to see a shocking news: laptop battery into the crash risks? Content of a UPS cargo plane in flight, because the cargo hold fire forced an emergency landing, killing three crew members sustained minor injuries. After investigation and discussion, that the laptop battery for the incident the culprit at the same time does not exclude the laptop battery will continue to brew the possibility of disaster.

With batteries, notebook computers to bring us wireless internet, mobile office life easier. Can fire incidents occurred from us to believe that one day laptops dell TD347 battery,dell U4873 battery will be completely taken out may be rejected, if, as it does desktop What is the difference? By then, holding laptop wireless Internet access at the beach to experience carefree dripping; in their own side of the balcony to enjoy the afternoon sun, while surfing the web ... ... and so on scenario will no longer be nice, because at any time in danger.

I ask, there is no mobile portable, there is no wireless Internet, consumers why to buy laptop computer? So, whether it is a fire incident, or a battery recycling events, not only causing trouble for consumers, more importantly, to the entire notebook industry, and even wireless network card, wireless routers and other related industries have a negative impact. Notebook industry, especially the battery suppliers, brand manufacturers, you should pay attention to this problem, consumers and society.

From the consumer's point of view, the purchase of notebook when the battery must be careful to understand the relevant information in the use of process dell D5318 battery,dell HD438 battery,dell KD186 battery, we need careful attention to maintenance.

Shanghai suburb of row upon row of new industrial park under construction in the factory, "Electric Vehicle Charging Station" greeted a few startled white text on red. This refreshing of the DELL laptop battery charging station is the builder of the emerging automobile manufacturers - BYD (BYD) car.

Shanghai is the sustenance of BYD Auto's future R & D center. Begin operation in 2003 R & D department has a team of 3,000 people are promoting hybrids, electric vehicles and fuel cell vehicle research and development. Displacement 800cc engine and equipped with self-developed lithium-ion battery hybrid has been developed successfully. Speed of 130km, fuel consumption in urban driving 100km only 4 liters. It is reported that a half hours to complete the charge, a charge can travel 570km a new dell 6Y270 battery,dell 75UYF battery generation of electric cars, BYD has been successfully developed.

Shanghai Automotive Group, in cooperation with Tongji University last year, had built a test fuel cell vehicles. SAIC-GM partners also have developed hybrid plan, and intends to produce 5 million units by 2010, environment-friendly vehicles. Toyota and FAW Group's joint venture plant from late last year, producing hybrids. Beijing Hyundai is also well-developed production plans. Once the project is the major vendors to achieve market-oriented, will benefit from the BYD charging stations and other facilities to be supported, which BYD is a good opportunity. Today, the "green car era" in China seems to have achieved in sight. The field of conventional gasoline vehicles are progressing steadily BYD maybe dark horse is the next dell C1295 battery,dell GD761 battery generation of cars.

SolarWorld AG in Germany recently celebrated its new Freiberg crystalline silicon solar cell manufacturing facility DELL laptop battery was established. The project invested 350 million euros, to the end of 2010 will be SolarWorld additional 500MW of annual solar cell production capacity, thus enabling the company's plant in Freiberg's more than the overall capacity to 1GW.

"Because of our R & D work and the latest technological processes, we will be able to resource-friendly and cost-effective way to produce silicon wafers", SolarWorld's chairman and CEO Frank H. Asbeck said. "Therefore, the Group is to continue along the path of continuous improvement of efficiency, which also reflected in the course of this year we will further reduce costs."

SolarWorld the establishment of the new plant will create 450 jobs. The company currently employees 1,500 people in Freiberg, Saxony is also the center of the company's largest industrial dell Latitude D430 battery,dell Latitude D500 battery employer.

February 5, 2009, the Ministry of Finance issued a document, confirming the central finance the purchase of new energy vehicles object of subsidies and standards, including car allowance enough for the highest standard DELL laptop battery for the maximum point of power ratio of more than 50% of the fuel cell buses, each Vehicle access to the promotion of 600 thousand yuan subsidy.

5.2 The financial subsidies to cover part of the manufacturers have hybrid cars and conventional cars spread, hybrid officially opened the prelude of the automobile industry

The financial subsidies the main basis for the establishment of standards for new energy vehicles with traditional car-based difference. We F3DM BYD's hybrid cars, for example, F3DM the technical parameters of the corresponding amount of a subsidy of 5 million, the market price of the vehicle from 14.98 million, of which the cost of lithium iron phosphate batteries to 5 million, the financial subsidies Pricing after the 998 million, the same configuration of the traditional F3 car is priced at 70,000 yuan market. BYD said, F3DM to achieve annual output of 200,000 units, the cost of lithium iron phosphate batteries dell Inspiron 1100 battery,dell Inspiron 1150 battery to 3 million, to consider subsidies, when F3DM price 7.98 million yuan, financial subsidies has been able to cover the hybrid electric vehicle with the traditional Automotive difference.

Through F3DM comparison with the traditional car shows, car driving 100,000 kilometers later, F3DM decrease in expenditure as compared with conventional cars 34.2 thousand yuan to implement the financial subsidies, F3DM the difference F3 with the traditional 2.98 million, has been demonstrated good value for money. We believe that, in addition to financial subsidies, the follow-up may introduce policy support, including tax relief for purchase of new energy vehicles, etc., when the economic benefits of new energy vehicles will be more pronounced.

F3DM endurance mileage reached 430 kilometers, of which pure electric mode, driving 100 km, the hybrid mode of travel 330 kilometers, a maximum speed of 160 km / hr.

Output power up to 125KW, to reach the level of 3.0L engine.

6, the hybrid automobile industry is the core value chain of lithium iron phosphate batteries and materials manufacturing

6.1 Distribution of Hybrid Electric Vehicle Industry Chain

Hybrid electric vehicle industry as a whole industrial chain can be divided into four parts

Metal materials --- "Battery Materials -" Automotive Power Battery - "hybrid electric vehicle

Hybrid electric vehicle industry, the automotive industry as the current representative of the third technological revolution and is today the automobile industry in the forefront of technology. As an emerging industry, we believe that who is technically have a leading edge, whoever will occupy the high ground in this emerging industry dell Inspiron 1300 battery,dell Inspiron 1420 battery.

As we have earlier analysis, the entire hybrid electric vehicle industry-oriented technological constraints are mainly two things: auto battery power and battery materials, industrial production. Lithium iron phosphate and iron phosphate lithium battery hybrid cars of the future development of the industry the most important direction of the enterprise master the production technology has the potential to become future industry star.

By the end of September 2008, Buffett's company bought Shenzhen BYD Company Limited (1211HK) 10% of the shares, bid 230 million U.S. dollars, Hong Kong dollars per share price of 8. BYD is currently the only vehicle the size of iron phosphate lithium battery production enterprises in the world's leader. From Buffett's investment ideas, we can see, technically leading edge is that we select investment targets of the primary consideration.

Our lithium battery industry chain, the specific circumstances of each link analysis:

6.2 Metal raw materials: lithium carbonate - a potential large production capacity, profitability will be lower than expected

Lithium carbonate is the production of rechargeable lithium salt and lithium based materials are widely used in batteries, glass, ceramics, aluminum products, lubricants, refrigerants and optoelectronics and other emerging applications.

The distribution of lithium carbonate downstream from the point of view, the battery industry's needs roughly about 25%, but in other industries the distribution of point of view, belong to the strong business cycle, in the current situation of the global economy into recession, the demand will be faced down. Therefore, industry is also part of strong cycle of lithium carbonate industry, a highly positive correlation with GDP growth.

Lithium carbonate industry has a very high threshold of resources, the global production capacity is highly concentrated. Lithium carbonate is currently the world's major manufacturers are mainly 3, Chile, SMQ, output of 28,000 tons, Chemetall of Germany and the United States FMC output of 2 million tons, total 78,000 tons, accounting for more than 90% of global production. Currently listed companies, CITIC Anhe Tibet Mineral aggregate production in 2008 will not exceed 4,000 tons.

We believe that the lithium battery industry scale, the hard drive the domestic lithium production of corporate profits increased sharply

1, the downstream distribution of lithium carbonate in the battery industry, the proportion of only 25%, most of the rest belong to the strong cycle of the industry, the battery needs to expand shortly irreparable decline in demand for other industries, the overall demand for lithium carbonate does not fluctuate greatly, Lithium Carbonate price difficult to be increased considerably.

2 Internationally, the three largest manufacturers of lithium carbonate have expansion plans, which, SMQ planned capacity expansion from 28,000 tons to 40,000 tons, Chemetall planned expansion from the current 18,000 tons to 30,000 tons, FMC expansion to 2.5 million tons, if all reach capacity, total capacity to exceed 9 million tons.

3, the domestic front, listed companies, CITIC Guoan design capacity of 20,000 tons long-term, Objective 3.5 million tons; Tibet Mineral design capacity of 10,000 tons, long-term objective 2.5 million tons; other Qinghai Salt Lake Group designs lithium industry and production capacity, respectively 10 thousand tons. To calculate the existing capacity has reached 50,000 tons, long-term dell Inspiron 1501 battery,dell Inspiron 1520 battery potential output 80,000 tons.

Short-term A-share listed companies, mining and CITIC Guoan in Tibet due to technical problems of production, annual output is only 2,000 tons, respectively, representing a lower percentage of main business income is difficult to drive performance increased significantly. Long-term perspective, the global lithium carbonate production capacity of the potential huge increase in demand even if the battery industry, but also difficult to drive lithium carbonate prices increased significantly.

6.3 The production of batteries and battery materials: Lithium iron phosphate is the future direction of technology in 2010, the explosive growth in demand will occur

At present lithium iron phosphate battery materials, the major competitors in the United States from the valence, A123 and Tianjin Strand.

Valence and its U.S. businesses in China, the United States, valence Vaillant began in 2003, the industrialization of lithium iron phosphate production, and the Chinese part of the lithium-ion battery manufacturers to cooperate, and the way in OEM production of 3-10AH polymer days to eat the same time, the building of production bases in Suzhou (Vaillant and Takeyasu), their own production polymer batteries. However, it did not sell to domestic customers cell materials.

A123 and its U.S. businesses in China are high his company is mainly engaged in metal ion doped lithium iron phosphate material commercialization of transport to do, some products have been used in Taiwan's manufacturers. Similar to the A123 and the valence, but also a way to OEM and domestic battery manufacturers to cooperate in construction of production base in Changzhou (high Bo). For domestic customers do not provide the same battery material.

Tianjin Stellan The company now has annual production capacity of 500 tons production capacity of lithium iron phosphate, and plans to expand production to 2,000 tons, the current BYD's lithium iron phosphate materials primarily to the company purchases, so we think, Tianjin Frost blue lithium iron phosphate material technology has been basically in line with large-scale production needs.

According to our statistics, the country to achieve mass production of lithium iron phosphate are 12 enterprises, the annual output 2400 tons

According to the planning of Science and Technology, China's development of hybrid cars will be stages in three stages

Recent development phase (2008-2012): hybrid electric vehicle mass industrial production, annual output reaching 1 million level, accounting for more than 10% of the total automobile output. The technology is relatively mature, and costs less "micro-hybrid" and "light hybrid" electric vehicle hybrid vehicles constitute the mainstream.

Medium-term development phase (2012-2020 years): With the advances in battery technology and lower prices, more significant energy-saving effect of severe hybrid vehicles and pure electric vehicles, hybrid vehicles in a dominant position, "micro-hybrid" and " light-hybrid "electric vehicle hybrid electric vehicle is composed of an integral part of the rest

Long-term development phase (2020-2030): hybrid car showed a substantial growth, accounting for more than 50% of the total automobile output, the traditional fuel vehicles, including alternative fuel vehicle production will fall to about 25% of the total automobile output

On the external front, the United States 2001-2007 terms of hybrid sales data, 2001-2007 hybrid car sales compound annual growth dell Inspiron 1521 battery,dell Inspiron 1525 battery rate reached an alarming 58.4%, the market in a rapid growth period, after taking office, Obama is declared to 2015, U.S. holdings of hybrid cars will be more than 1 million.

At present the annual domestic demand for lithium iron phosphate of about 8,000 tons, the output of 2400 tons of lithium iron phosphate production technology threshold is high, most of the time of volume production manufacturers can not guarantee the stability of the product, we expect the current domestic-P acid, lithium iron actual annual production is currently lower. With the hybrid automobile industry of the advent of lithium iron phosphate will face a huge market for cake. From a domestic perspective, Shenzhen BYD's hybrid cars F3DM officially listed at the end of 2008, and in 14 cities in sales, its follow-up of the E6, F6 and other models will be available in 2010, hybrid electric vehicle industry, an era of has arrived.

According to our statistics for 2008-2009, the domestic total of 50-60 core home appliance manufacturers will soon or have already completed the purchase of production lines to carry out capacity expansion by 2010, demand for lithium iron phosphate explosive growth will occur.

We expect that by 2010, the domestic auto industry of the early hybrid, lithium iron phosphate of the annual demand will be more than 15,000 tons.

According to the U.S. A123's forecast, by 2010, the global lithium iron phosphate supply gap will reach 10 million tons.

6.4 The hybrid electric vehicle manufacturing enterprises: lack of core cell technology is difficult to enjoy the industry growth

Key technology of hybrid electric vehicle is powered car battery, car battery power costs account for the full cost of the 30-50% share in the current A hybrid electric vehicle production enterprises lack the basic capacity of the battery powered car, the basic use of outsourcing. Consider the state financial subsidies, hybrid cars and conventional cars of the gross profit margin gross profit margin will not be much difference, it is difficult to enjoy the industry growth in excess profits.

At the same time with the current domestic electric vehicle batteries and vehicle production capacity is only BYD a business, Buffett's investment in the enterprise took a fancy to their own core technology of hybrid cars --- lithium iron phosphate batteries.

7, looking for lithium power industry's future stars of Enterprise: technological advantages will determine the company's future

7.1 hybrid auto industry to judge the investment value chain, each link

The current A-share market, involving a hybrid of a listed company listed in the table below

We judge:

The upper reaches of metal raw materials: The Tibetan mining and CITIC Guoan technical problems because of production, annual output is only 2,000 tons, respectively, representing a lower percentage of main business income is difficult to drive performance increased significantly. Long-term perspective, the global lithium carbonate production capacity of the potential huge increase in demand even if the battery industry, but also difficult to drive lithium carbonate prices increased significantly.

     Cathode materials: a stable cathode material lithium iron phosphate production capacity of enterprises, will become the future star lithium industry.

Middle reaches of the battery and battery manufacturing: CITIC Guoan Mengguli controlled mainly produce lithium cobalt oxide batteries, battery powered car is not the future direction of development; Section power far from the main products are nickel-metal hydride batteries, although most of the car power battery using nickel-hydrogen batteries, but we believe that lithium-ion battery will replace the current nickel-metal hydride batteries.

Upstream and downstream manufacturing of hybrid cars: At present, most domestic manufacturers lack of hybrid vehicles hybrid electric vehicle powered car battery manufacture and production of core technology, it is difficult to enjoy the industry growth opportunities. BYD has a core of hybrid cars lithium iron phosphate battery technology capacity, will in the future market competition dell Inspiron 1720 battery,dell Inspiron 1721 battery.

1, the coming era of new energy vehicles

1.1. Endeavoring to develop new energy Sony laptop battery vehicles are a necessary requirement of energy and the environment

According to the U.S. Energy Information Administration EIA International Energy Outlook released by the world's energy market by 2030, consumption in 2005 is expected to increase by 50%.

As energy consumption increases every year, carbon dioxide emissions will also increase the current carbon dioxide emissions, 25% comes from cars. 2030 will be 28.1 billion tons in 2005 to 42.3 billion tons. In China, the vehicle emission pollution has become an important factor in urban air pollution, China's carbon dioxide emissions now ranks second in the world emissions of carbon dioxide pressure will increase sony PCGA-BP1N battery,sony PCGA-BP2E battery.

1.2. China's development of new energy vehicles more urgent pressure

In recent years, the rapid development of China's automobile industry has become the world's fourth largest auto producer and third largest auto consumer. According to the State Council Development Research Center estimates that by 2010, China's car ownership will be close to 6 10 million in 2020 will reach 140 million, respectively, motor vehicle fuel demand 138 million tons and 2.56 million tons, the country's total oil demand for the year 43% and 57%. China's oil shortage of resources, the current oil imports, the percentage of double-digit annual growth in 2010, import dependency is expected to be close to 50%. Therefore, great efforts to develop new energy vehicles, electricity generation of oil, is to ensure China's energy security, strategic measures.

Therefore, great efforts to develop new energy vehicles is to achieve China's energy security, environmental protection and China's automobile industry by leaps and bounds, and sustainable development needs.

2, hybrid electric vehicle will be the development of new energy vehicles in China the main direction of

2.1 Definition of hybrid cars

The new energy vehicles refers to the use of unconventional motor vehicle fuels as a source of power (or use a regular car and then, using a new type of power plant, including hybrid electric vehicle (FCEV), pure electric vehicles (BEV), fuel cell electric vehicles (PCEV) and other new energy automobiles.

At present a variety of new energy vehicles, hybrid electric vehicle is currently the research focus of new energy vehicles, has achieved a small-scale industry production. Hybrid electric vehicle by the electric motor as an engine-driven auxiliary power in vehicles.

2.2 Classification of Hybrid Electric Vehicle

Hybrid vehicles currently are mainly three kinds:

The main power to the engine, the electric motor as an auxiliary power of the "parallel approach"

Low-speed electric motor drive alone when traveling speed by the engine and electric motor matching the "Series - parallel approach"

Use only the electric motor driving the "series sony PCGA-BP2EA battery,sony PCGA-BP2NX battery approach"

We believe that: the industrialization of hybrid electric vehicle production, the various functional modules through the car's development and to gradually promote the automotive power-oriented, from only have the automatic start and stop, idle shutdown feature "micro-hybrid" in order to parallel hybrid engine the subject "light hybrid" and in hybrid style characterized by "full hybrid", with the equipment, power gradually increase and ultimately the transition to a tandem-style "rechargeable hybrid", and ultimately pure electric vehicles industrialization.

3, vehicle battery power is a hybrid of the key automotive industry, lithium-ion batteries will become the future star of vehicle battery power

3.1 Vehicle Power battery has a very high performance requirements of

Drive motor generator set + + energy storage systems constitute a hybrid vehicle underlying technology platform, the current generators and drive motors have been developed to achieve technological breakthroughs, energy storage devices become a restricted hybrid vehicle to achieve the industrialization of a major bottleneck in .

The current hybrid vehicles use a variety of battery as the energy storage device, automotive battery power with a strong performance requirements:

High energy density: at least with gasoline rather ,100-1000Wh / Kg

High power density :300-1500W / Kg

Long life: the life of vehicles from the same

Wide operating temperature range: -45-80 ¡æ

High security and reliability

Low Cost: ¡Ü 50-100 $ / KWh

Environmental pollution

3.2 Li-ion batteries have a very high-performance advantage is the inevitable development of the future direction of battery power

Now commonly used in secondary batteries, including rechargeable lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries. Compared with the traditional lead-acid and nickel-metal hydride and nickel-cadmium batteries, the lithium-ion battery has a short history. Lithium-ion battery is known as the most superior performance of rechargeable batteries, known as "the ultimate battery" by the market, attracted worldwide attention. As mobile phones, notebook computers, digital cameras, MP3, MP4, Bluetooth, PDA and portable video cameras and other consumer and portable electronic products continued strength in demand for lithium-ion batteries has remained fairly high growth rate, the market for lithium-ion batteries to guide the huge demand for lithium-ion battery industry continue to be strong, but also to make lithium-ion batteries sony PCGA-BP2NY battery,sony PCGA-BP2R battery in electric vehicles the application possible.

(1) The single cell voltage up to 3.7V, is a nickel-cadmium batteries, nickel-metal hydride batteries 3 times, nearly two times more lead-acid batteries

(2), light weight, than the energy of large, up to 150Wh/Kg, is a nickel-metal hydride batteries two times, four times the lead-acid batteries, so the weight is the same energy, one-third to one fourth lead-acid batteries

(3), small size, high reach 400Wh / L, the volume is one-half to one third of lead-acid batteries. Provides a more rational structure and a more aesthetic appearance of the design conditions, design space and possibilities.

(4) long cycle life, cycle times of up to 1000 times. In order to maintain the 60% of the total volume, battery charge and discharge cycles 100% up to 600 times more than the useful life of up to 3-5 years, the life expectancy of about two to three times the lead-acid batteries

(5) self-discharge rate is low, less than 5% per month

(6) allows a wide operating temperature range, low-temperature performance, lithium-ion battery in -20 ¡æ ~ +55 ¡æ work between

(7) No memory effect, so every time the former do not like the nickel-cadmium rechargeable batteries, nickel-metal hydride batteries, need to discharge, can be recharged anytime, anywhere. The battery charge and discharge depth, little impact on battery life can be full-filled the whole place

(8) pollution-free, lithium batteries do not exist in toxic substances, so called "Green batteries", while the lead-acid batteries and nickel-cadmium batteries because of the existence of harmful substances as lead and cadmium, and environmental pollution a serious problem

3.3 The development of lithium-ion batteries have a unique advantage in China

In addition to lithium-ion battery itself has the performance advantage, we believe that lithium-ion batteries for hybrid vehicles, as well as pure electric vehicles, energy storage devices, the development of lithium-electric cars, our country has unique conditions for

(1) resources

Li-electric cars, the most important key components of a lithium-ion power batteries and permanent magnet synchronous motor, lithium-ion battery the principal raw material lithium, manganese, iron, vanadium and other resource-rich in our country are. In China, it is in permanent magnet synchronous motor === rare-earth permanent magnetic material resources, power, electric cars for the lithium material guarantee.

(2) technical superiority

China's low-power lithium-ion batteries already industrialization, formed a complete integrated upstream and downstream industry chain, battery production of more than one-third of the world market, lithium-ion battery technology has reached the international advanced level, industry-oriented conditions basically mature , Shenzhen BYD is lithium-ion battery technology, the international leader in industrial production has been achieved.

Therefore, we believe that both the characteristics of lithium-ion battery itself, or China's current situation, the development of lithium-ion battery would be China's new energy automotive industry of the principal directions.

4, power lithium-ion battery materials: lithium iron phosphate cathode material of choice will be

Power lithium-ion battery is a lithium-ion battery materials, a high-energy density batteries, is designed for motor vehicles powered by lithium batteries, has zero pollution, zero through the arch, a high energy density, small size and long life cycle of the advantages of is the development and application of battery power at home and abroad trend.

4.1 power lithium battery industry, the choice of lithium iron phosphate batteries ---

Mainly by the internal lithium-ion battery cathode, anode, electrolyte and isolation membrane composition, positive and negative electrodes and electrolyte materials, the differences in the different processes have different battery performance, particularly in the performance of cathode materials, the greatest impact on the battery. Currently on the market lithium-ion battery cathode material is mainly lithium cobalt oxide (LiCoO2), plus a few to take lithium manganese oxide (LiMn2O4) and lithium nickel oxide (LiNiO2), as well as ternary materials (Li (NiCo) O2) as a cathode material The lithium-ion batteries sony PCGA-BP2S battery,sony PCGA-BP2T battery. Lithium iron phosphate material is a newly developed lithium-ion battery materials.

In particular, should be noted that, as a vehicle power energy storage devices, security, performance, in particular, need attention. As the lithium batteries of high specific energy, materials, poor stability, lithium prone to security issues, currently the world's leading mobile phone and notebook computer batteries (lithium cobalt oxide cathode materials and ternary material) production enterprises, Japan's Sanyo, Sony and other companies require battery explosion spray rate was controlled at 40 ppb (billionth) the following, domestic firms can achieve ppm (parts per million) level was already pretty good, while the power capacity of the battery cell phone battery last for more than a hundred times Therefore, the safety of lithium is highly demanding. While the cobalt lithium batteries and battery with a ternary materials, lighter, smaller, etc., but they are not suitable for motive power batteries used in electric vehicles.

The same time, the main raw material for lithium cobalt oxide cobalt rare in China's reserves, at present 80% of the metal cobalt basic rely on imports, large-scale use in China is difficult.

Judging from the current variety of lithium-ion battery performance comparison we can see that, iron phosphate lithium battery is the most suitable for industrial use of electric vehicles, lithium-ion battery. Thus, taking advantage of the large-scale production of lithium iron phosphate and iron phosphate lithium battery technology company, will in the future competition in the electric automobile industry leader.

5, policy boost, hybrid technology has the advent of the automobile industry
