? Nov. 19, 2009 - Whither the post-petroleum era Battery Industry
In recent years, with the electric power, coal, oil and other non-renewable energy sources frequently in an emergency, energy is increasingly becoming a bottleneck restricting the laptop battery development of the international economy. The post-petroleum era, so that people will once again focus attention to a new energy development and use of, this has to a certain extent, the promotion of the battery power system industry. People will turn its attention to lithium-ion batteries, fuel cells, solar cells, wind energy dell Inspiron 1150 battery research and development. According to experts, China's battery industry in terms of technological improvements or in the structure of demand, have ushered in a new era of development.
Fuel Cell
Is not easy to say love you
In today's global energy crisis era, finding new energy as a substitute for fossil fuels is a priority. Because of its easy to get fuel for fuel dell Inspiron 6400 battery, environmental protection and sustainable use of the advantages of the battery industry and became the new topic, particularly in the automotive industry in the promotion of pollution-free fuel cell zero emissions, the relevant parties is given a high degree of recognition and evaluation of . In recent years, Europe and the United States, Japan and other developed areas and the state has put a lot of the fuel cell R & D strength, China as early as 50 years in the 20th century to carry out fuel-cell research, is now a key material in fuel cells, the key technological innovation has achieved many breakthroughs. 2008 Beijing Olympic Games on the use of green fleet of 20 self-developed fuel-cell electric cars.
According to the experts predict that by 2013 the global fuel cell market could reach 35 billion U.S. dollars. In 2006, the fuel cell performance will be improved, its sales will also be significantly increased. Fuel dell Inspiron 1150 battery growing on a global scale, so that many people in the industry that fuel cells will have broad market space, will become a trend in the development of battery industry. However, there are different voices in there.
"Fuel cells can only say that the development of a direction, but not become a trend." China Battery Industry Association, says the Secretary-General Wang Jingzhong. "At present, both foreign and domestic, fuel cells are still in development stage of a trial and did not form a mass, industrialized production." According to Wang Jingzhong introduction, the reason why fuel cells did not form industrial production, mainly by two factors, One is subject to material constraints, fuel cells require platinum as dell GD761 battery Coal agent, and such materials costs very expensive. It is understood that the global annual production of platinum in 2006 to 200 tons in 2007 to 220 tons. China's annual output of only about 4 tons and imports about 40 tons, mainly used in chemical industry and chipped jewelry. "Every 50000 fuel cell electric cars would need at least 1 ton of platinum, just from this rare and expensive platinum resources are concerned, how to support affordable fuel cell electric vehicle industry to be?" Chinese Academy of Engineering, YANG Yu-sheng also expressed of the same opinion.
The second is a security risk. Wang Jingzhong that fuel cells are primarily used in the car, then install the bottle whether the quality of fuel to cross the border whether a collision will not occur under high temperature and so on will have security implications.
This year in May, the U.S. government's energy minister Obama officially announced that the government cease its support for fuel cell electric vehicle research and development. The fuel cell electric vehicle has been vigorously advocated by the Bush administration as "hydrogen economy" theory of the "magic." "In the substitution of new compaq EVO N400c battery platinum catalyst technology has been no fundamental breakthrough in this problem, before fuel cell electric vehicle can not be big development. Moreover, hydrogen is a secondary energy to primary energy consumption can be obtained, the total energy of the fuel cell power conversion efficiency of was not high. do basic research is the key. "YANG Yu-sheng.
Solar energy, lithium-ion battery
Sync with the developed countries
"At present, China's battery industry in research and development of new battery technologies and abroad at the same starting line, just to see who will have a bigger breakthrough." Wang Jingzhong confidently say: "Now our focus is mainly on the lithium-ion batteries sony VGP-BPS5A battery,sony VGP-BPS8 battery, solar cells in the development and research. "
According to Wang Jingzhong New China was founded, China's battery industry is in a destitute condition, the battery is only more than 3000 million total production value of less than millions of dollars in total for the workshop-type enterprises. While 60 years later, China has become the world's first battery-producing countries, production increased by 1000 times, sales revenue increased by tens of thousands of more times, the battery varieties from the new China was founded, early dry and paste-type open-type lead-acid batteries such as several hundreds to the present. Advanced mercury-free alkaline manganese batteries, valve-sealed lead-acid batteries, lithium-ion battery, Ni-MH batteries, solar cells and other products has become China's battery industry's leading products, technologies, equipment, and product quality has been synchronized with the developed countries, China's the battery industry has formed a complete industrial system supporting production and research, are moving toward a world power in the battery industry. As a new energy industry, an important component of solar, wind and other renewable energy sources, electric vehicles and other emerging industries, the rise of China Battery Industry is a new round of take-off and laid a solid market foundation.
It is understood that, after years of development, China's new toshiba PA3176U-1BRS battery energy industry has made considerable progress, China's solar cell production capacity has reached 2,900 megawatts, ranking first in the world. The lithium-ion batteries because of its cycle of good performance, high safety factor advantages in electric cars has played an important role.
China Battery Industry Association, Jin-Liang Wang, director of the Technical Committee also believes that the new battery technology is affecting the world science and technology and cutting-edge high-tech industrial development, one of the battery industry is also the most development potential in the 21st century, a sunrise industry, with the rapid development of world science and technology, Battery Industry in China's national economic development will play an increasingly important role. China is now toshiba PA3178U-1BRS battery the world's largest battery producer and the largest battery consumption of the country, with oil and other energy crisis escalating, people become increasingly aware of environmental protection, the battery industry is also seeking new opportunities and challenges in the development and breakthroughs.

? Nov. 11, 2009 - After recharging a laptop battery for a long time it gets green
We used to make notice that after recharging a laptop battery for a long time it gets green. It is because a user should replace it more often. The green colour shows you that the battery is becoming exhausted. The more recharges are made the shorter is the working period of a battery. Chief Executive of Boston Power Christina Lampe-Onnerud says:
“With most batteries, you get four hours. A few months later, it’s two hours and then later it’s one hour. The biggest disappointment with notebook computers is battery life and performance”.
laptop batteries is known as a user of Sonata batteries produced by Boston Power. HP is going to resell Sonata in some users’ netbooks as an upgrade option. They say:
“It does not come standard with any notebook”.
The consumers will be able to choose between building the batteries up as replacements and taking them as an upgrade option. Sonata batteries, as its producers say, has only one process compared with the common ones which have a number of processes, and the heat which is generated by Sonata, is the result of the generated wasted energy.
A three-year working warranty is given to inspiron battery. And according to Lampe-Onnerud this period is longer than for other average ones. Moreover they have additional safety features. She said also:
“If it is really damaged, I don’t want it to work again”.
There is also bonus, Latitude batterycan be charged to 80 percent capacity in about 30 minutes. And it takes one or two hours to get to 90% capacity for common notebook batteries. In conclusion of this short story it is suffice to say that nowadays Boston Power is producing their batteries in Taiwan and soon is going to make them in China as well in a newly constructed plant. |

? Oct. 16, 2009 - Battery use and maintenance issues requiring 8 attention
1. Batteries do not long, it will slowly self-discharge, before being scrapped. Therefore, from time to time should be to start a car, to recharge the HP laptop battery. Another option is to battery pull down on the two electrodes, must be noted that from the electrode column Unplug the positive and negative electrode 2 lines, first disconnect the negative cable, or remove the negative and car chassis connection, and then and then pulling out with a positive sign (10) and the other end. Batteries have a certain life, to a certain period of time to be replaced. In the replacement also have to follow the order, but in the electrode line Jieshang Qu, the sequence, by contrast, first, then positive, and then draw a line negative. 2. Batteries build capacity reflected in the instrument panel. When the ammeter pointer shows build capacity is low, a timely charge. Sometimes the road was found not enough power, the engine can not start another flame, as a temporary measure, you can seek assistance to other vehicles, with other batteries on the vehicle to launch vehicles, the two batteries connected to the anode and cathode, anode and cathode connected to hp 338794-001 battery , hp 361742-001 battery.
3. Electrolyte density should be in accordance with different regions and different seasons in accordance with standards adjusted accordingly.
4. Electrolyte losses should be added distilled water or special rehydration, should not have to use clean drinking water instead, because purified water contains many trace elements, the battery will cause adverse effects.
5. To start the car, the uninterrupted use of the opportunity to start leading battery damage due to excessive discharge. Use the correct approach is to launch a car each time, total length of no more than 5 seconds, re-start interval of not less than 15 seconds. Several times to start the car's not the case from the circuit, ignition coil, or asphalt, and other areas to find a cause.
6. Everyday traffic should always check whether the ventilation hole battery cover, if the battery cover holes blocked, the resulting hydrogen and oxygen, did not break out, expanding the electrolyte when the battery case bursting will affect the battery life of .
7. Check the battery's positive and negative signs of whether they were oxidized, you can use hot water from time to time poured battery wire connections.

At present, China is the world's largest manganese / alkaline manganese battery producer, is the world's second-largest lithium-ion battery producer and exporter. In 2005, China's battery products are exported to more than 150 countries and regions, Asia is the largest exporter of China's battery, while the Hong Kong Special Administrative Region has become China's largest battery export transit. It is understood that a quarter of China's export volume batteries exported to Hong Kong first, and then re-exports through Hong Kong to other countries and regions in the world, some of which they were imported into the mainland through Hong Kong. The following are various types of cells in the first half of this year the export of data (see Table 2) analysis and full-year exports are forecast to: Zinc / alkaline manganese batteries: in the first half, China's export of alkaline manganese batteries 2.21 billion, export value of 153 million U.S. dollars; ordinary zinc-manganese batteries (manganese dioxide) export 7 billion, export value of 365 million. Expected full-year 2006 exports of alkaline manganese batteries will rapidly increase the annual growth rate will reach 20 percent, export volume will more than 4.5 billion. While the ordinary zinc-manganese batteries batteries due to the European Union Directive on the mercury content limit will be reduced this year's export volume is expected to the annual dell Inspiron 1100 battery, dell Inspiron 1150 battery export volume of 14.5 billion, lower than in 2005 about 8%. Lithium battery: in the first half, lithium battery for the 154 million export volume, exports amounted to 23.04 million U.S. dollars. China's lithium battery is expected full-year exports will be more than 300 million, but export prices fell too fast, the export value in 2005 may be flat or down slightly. Nickel-cadmium batteries: in the first half, China's export volume of nickel-cadmium batteries 317 million, exports amounted to 148 million. As the European Union since July 1, 2006 implemented RoHS environmental directive, China's exports to the EU in the future of nickel-cadmium batteries will be reduced gradually. At the same time, China will be held March 1, 2007 started the implementation of "Electronic Information Products Pollution Control Regulations," the use of nickel-cadmium batteries will be subject to certain restrictions. The next few years, nickel-cadmium batteries in consumer electronics products, the dosage will be gradually reduced, but power tools, emergency lighting is still the major market for nickel-cadmium batteries. Ni-MH battery: in the first half, China's export volume of nickel-metal hydride battery 413 million, exports amounted to 256 million U.S. dollars is expected in 2006 than in 2005 export volume growth of about 10% to reach 960 million. As the global environmental protection growing louder and louder, Ni-MH battery will gradually occupy nickel-cadmium batteries in the consumer electronics market share dell Inspiron 1300 battery, dell Inspiron 1420 battery. Starting with the lead-acid batteries: In 2005, starting with the lead-acid batteries in China export volume was flat with the previous year, export value has increased by 34.6% year on year, mainly because of high lead prices lead to higher export prices due to the battery. In the first half, starting with the lead-acid batteries in China amounted to 9.8 million exported, export value of 87.5 million U.S. dollars, in 2006 the annual export volume is expected to grow by 7% to 10%. In recent years, starting with lead-acid batteries in China export volume has no significant growth, the proposed restrictions on government departments lead the export of raw materials, high energy consumption and improve China's lead-acid battery products in the international market, competitive advantage. Other lead-acid battery: Other lead-acid batteries are generated mainly refers to VRLA batteries, in recent years, China's exports of such products is growing rapidly. In the first half, China's export volume of valve-regulated lead-acid batteries for 71.87 million and exports amounted to 407 million U.S. dollars, in 2006 the annual export volume is expected to grow by 15% to 20%, export volume will more than 160 million.

? Oct. 6, 2009 - Analysis of Li-ion battery problem
Continued last month, storm out for faulty notebook batteries, Dell, Apple, after the news of a large-scale recycling operations, recently have reported that Matsushita is recalling in Japan of the 6000 domestic sales of DELL laptop battery due to overheating because there is also a hidden danger .
Although the size of the Panasonic battery recall than the Dell and Apple before the small size of the large, but had to let us re-examine the notebook lithium battery safety issues. In this regard, lithium-ion battery industry expert Steven Carlson recently said that lithium batteries frequently have problems not because of lithium batteries due to their technical skills, the reason should be multi-faceted.
With the continuous development of notebook computers, one notebook battery life also put forward higher requirements, which enables manufacturers to face enormous challenges. The reason unexpected, Carlson said the main reason is because the standard battery manufacturers demanding.
Made for the consumer demand, battery manufacturers have to come up with a long life products, but at the same time to ensure product safety, reduce heat and also consider its own manufacturing costs, which is now facing manufacturers problems. Carlson said that as the temperature exceeds the tolerance range of the battery itself, the lithium batteries will enable the "Auto-off" technology to prevent a fire, so the dell Inspiron 1100 battery,dell Inspiron 1150 battery is not its technical reasons unforeseen.

? Sep. 28, 2009 - The new energy automotive batteries depth analysis of current situation and trends
In recent years, new energy vehicles more and more attention, just past the Shanghai International Auto Show, the new energy vehicles is pocketed the limelight, in the total area of 17 million square meters of Shanghai International Automobile Exhibition Hall in all , "EV" (electric technology) and "Hybrid" (hybrid technology) propaganda banners everywhere identified with the body. Not only display a variety of foreign and joint venture of new energy vehicles, China's own laptop battery brands to be outdone, attempted to research and development of new energy vehicles and foreign automobile technology is relatively mature to compete. China auto industry analyst with investment adviser Lee Sheng-mao said, from the development trend, new energy cars is undoubtedly the future automotive development. The new energy vehicles, including hybrid electric vehicle (HEV), a pure electric vehicles (BEV), fuel cell vehicles (FCEV). Batteries, electric motors and energy conversion control system is the most important components of new energy vehicles, while the battery to achieve fast charging, security and other high-performance, is a technical threshold of the highest, most concentrated part of the profits, the investment of new energy power batteries will take time and technology accumulation dell Inspiron 1721 battery, dell Inspiron 2600 battery. Status of the new energy automotive batteries By the international financial crisis, General Motors, Chrysler and other auto giant suffered heavy losses. To be born again, car prices on the one hand cut through layoffs, selling assets, such as Brokeback to survive, while sparing no effort in the development of new energy vehicles in order to carry a downturn, China's new production cars by 2012 there were 10% of energy-saving and new energy vehicles The goal is clear-cut. The future of new energy vehicles gradually replace traditional gasoline car has become a consensus of countries to develop the automotive industry, as a core component of the motive power by businesses and investors are more optimistic. Power battery is the key to the development of new energy vehicles: hybrid electric vehicle is the best transitional product, but a pure battery-powered cars is the future direction of development, core technology, a breakthrough in battery technology. At present many well-known car manufacturers are working to develop battery-powered electric vehicles, such as Ford, Chrysler, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury so. While the domestic car manufacturer BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by lithium dell Inspiron 2650 battery, dell Inspiron 5150 battery power. China's new energy automotive battery industry, Europe and the United States began late in the day, but the development is very fast, power battery research and development has also invested a great deal of financial and material resources. 863 plans to set up an electric vehicle major projects, Institute of Physics, Chinese Academy of Sciences, Beijing Nonferrous Metal Research Institute, China Electronics Technology Group Corporation 18th Research Institute, and other units participating in the project were the development of EV and HEV, with the two power batteries, of which some units have adopted a security system for cathode active materials of manganese. "Eleventh Five-Year", 863 electric vehicles on the major projects also HEV, PHEV (plug-in hybrid vehicles), FCV (fuel cell vehicle) with power lithium-ion battery and battery research and development of key materials for support. Bottleneck in the development of new energy automotive batteries The development of new energy vehicle power batteries are good prospects, but the market is still low, take time away from the real industrialization, and, power battery enterprises really want to become bigger and stronger, but also to withstand industrial scale, large-scale R & D investment and Foreign giants squeeze test. China auto industry analyst with investment adviser Lee Sheng-mao said power battery succeed in the short term large-scale commercialization is not the real reasons are: First, production costs are high. At present the use of electric vehicle battery power to account for the cost of one-half of vehicle cost. A full-fledged electric car by Curb Weight 1.5 tons, the maximum speed of 130Km / h, on a single charge driving range of 200Km (60Km / h constant speed) to calculate the required lithium batteries (76AH, operating voltage 320V) will be weighed 350Kg , only the price of the battery at about 100 thousand RMB or so. Even a major breakthrough in battery car company, is recognized for the external dual-mode electric vehicles than the existing models on the same level of prices higher than the 7 to 80 thousand yuan. So many consumers are willing to spend the equivalent of 150,000 to buy an engine of Xiali compact cars do? This is the world's electric car can not form one of the root causes of climate. There is no a cost-effective battery-electric vehicles can meet the performance and cost of industrial needs dell Inspiron 5160 battery, dell Inspiron 6000 battery. Second, there are many technical bottlenecks. In addition to the problem difficult to resolve fast charging, the battery in a different climate, traffic, and operating conditions at run time, the battery performance of a variety of unstable, the result will result in electric car vehicle performance (speed, acceleration, a charge added driving mileage) continues to drop. For example, the electric air-conditioning power consumption power in the 3 ~ 4kw, general open air conditioning, electric cars, to reduce the driving range of at least one-third, in other words, the original can travel 90 kilometers of electric cars, when using air conditioning when you can only travel 60 km. Third, the infrastructure supporting almost zero. Commercialization of electric vehicles, including charging station infrastructure, networks, vehicle maintenance, service network, various forms of battery sales and service networks. Investment in building these infrastructures need to spend huge amounts of money. In a city to build at least a dozen to several dozen public charging stations in order to meet the urban areas of the taxi, private car, commercial vehicle fast charging needs. Investment opportunities in the new energy automotive batteries Analysis The new energy vehicles demanding on the battery, you must have a high specific energy, high specific power, fast charging and deep discharge performance, and requires the cost as low as possible, the use of Shou as long as possible. Motive power batteries are mainly lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries and lithium batteries. The traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride battery technology itself is relatively mature, but they are used in automotive batteries as a power, then there exists a larger problem. Lead-acid batteries as a relatively mature technology, because of its low cost, but also to high-rate discharge, remains the only available for mass production of electric vehicle batteries. But the lead-acid battery specific energy, specific power and energy density are very low, as a power source for an electric car can not have good speed and endurance mileage. Other more mature cells, such as nickel-cadmium batteries and nickel-metal hydride batteries, although the performance is better dell Inspiron 700m battery, dell Inspiron 710m battery than lead-acid batteries, but it contains heavy metals, higher prices, and exhausted after abandonment can cause serious pollution to the environment, are not suitable for mass production. At present, more and more car manufacturers to choose from lithium batteries as a new energy car battery power. Li-ion battery has the following advantages: small size, light weight, high voltage (which is nickel-cadmium batteries, nickel-hydrogen batteries 3 times) than the energy of large (up to 165WH / kg, nickel-hydrogen batteries 3 times), loop-shou long, self-discharge rate is low, no memory effect, no pollution, safety and good. Of these, lithium battery materials can be divided into electrode (positive / negative) materials, separator and electrolyte. Li-ion battery cathode material is the core of the current lithium cobalt oxide, lithium manganese, lithium and nickel-cobalt-manganese-based lithium iron phosphate. Ze Yi graphite anode material, solid carbon particle-based; in the middle of positive and negative electrodes while the battery electrolyte and separator. In the lithium battery industry chain, the current capacity comparison, due to high barriers to entry, lithium battery cathode material is the smallest capacity, which is the whole industry chain, the most promising aspect. Cathode materials currently in production companies are: China Baoan, CITIC Anhe Shanshangufen, BYD. Compared with the cathode material, anode material for lithium battery costs accounted for the proportion of low-and domestic-oriented industries has been realized, the negative electrode materials, graphite, solid carbon particle-based. Currently engaged in lithium battery cathode material production enterprise in China, the top three national security, Shanshangufen, Long Sand Sea capacity, at present anode material able to basically meet the needs of the domestic market, but with the increasing popularity of new energy vehicles, the future market for this one a huge gap in demand will occur. Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. Main raw materials for the electrolyte lithium hexafluorophosphate, accounting for about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, priced at 40 yuan / ton, gross margin as high as 75%, but the market was largely Kanto Electric the chemical industry, SUTERAKEMIFA, Morita chemistry, several Japanese companies a monopoly. Corporate domestic rarely can produce lithium hexafluorophosphate, and in this one Juhua walking in the forefront of domestic enterprises, already have well-fluorine chemical industrial chain, advanced technology and rich fluorine chemical fluoride raw material. In addition, the domestic lithium battery electrolyte in the production enterprises are Shanshangufen, Huarong Chemical Co., Zhuhai race Wei Electronics, Tianjin, cows, golden Shantou, Guangzhou, more than a heaven-sent, etc. 10. Among them, Huarong Chemical Co., Zhuhai race weft electronic positioning high-end market, other companies can only do low-end market. Prospect of new energy automotive batteries With the global scope of the increasingly serious energy crisis and environmental pressures, in recent years, the world's major automobile-producing countries regard the development of new energy vehicles, as to make industry more competitive and maintain sustainable economic and social development in a major strategic initiatives. The new energy vehicles to become a new growth point of the market, even in the auto market downturn, the U.S. hybrid vehicle sales are still growing. China auto industry analyst with investment adviser Lee Sheng-mao said that China's traditional vehicle for at least 10 years behind the Western countries, however, new energy vehicles as an emerging area of China-made cars in this respect no less significant. At present, the Chinese government has put the development of new energy vehicles as a national strategy to promote the hope that through the development of new energy vehicles in the world automobile industry niche. The Ministry of Finance and the Ministry of Science recently issued a notice to cities in 13 energy-saving and new energy vehicle demonstration and extension work, and clearly the central finance the purchase of new energy vehicles will be given a one-off grants. Preliminary consideration, in the next four years, to take financial subsidies to support the part of the city in public transportation, rental and other public services, promoting the use of energy-saving and new energy vehicles for more than 60000. Li Sheng-mao is expected by 2012, the annual production of new energy vehicles will reach 1 million, according to each new energy automotive batteries costs 7 million lithium iron phosphate cathode material 52 kilograms, 41 kilograms anode material, electrolyte 40 kg calculations . 1 million hybrid vehicles will drive the 52,000 tons cathode material, anode material for 41,000 tons, 40,000 tons electrolyte needs. For domestic battery manufacturers, this would be a gross output value of 70 billion yuan of the big cake. If calculated according to passenger cars, this value will increase three times - each hybrid passenger car battery demand is four times that. In summary, the new energy automotive batteries dell Inspiron 630m battery, dell Inspiron 6400 battery, dell Inspiron 640m battery though there are still many problems, but with the energy, environmental pressures and technological advances, the future of new energy vehicles instead of the traditional automotive trend will become a necessity, power batteries as a new energy vehicles in the "heart" , will result in a huge industrial and economic effects on the battery raw material suppliers and manufacturers who are huge commercial cake. |

? Sep. 28, 2009 - 2012 will bring new energy vehicles demand for lithium battery separator turned 10 times
According to the Investment Adviser Lee Sheng-mao auto industry analyst noted that with the gradual promotion of new energy vehicles, the future demand for power lithium battery materials will be detonated. Right now, although China electric bicycles, motorcycles and other light electric vehicles to retain volume has more than 50 million, ranking first in the world, thus derived are also a large number of laptop battery manufacturers. However, some key technologies, it is still foreign to master, lithium batteries with the electrolyte membrane, is one example. Lithium-ion batteries with a working voltage due to the high energy density (light weight), no memory effect, long cycle life, and pollution-free, etc., all kinds of electronic products to become the main power supply, the global demand for lithium-ion DELL laptop battery average annual increase of 30 % or more, the market is huge. China's current lithium-ion battery production accounted for more than a third of the world's total and more than 100 manufacturers of lithium lithium-ion battery materials, demand, Lithium ion battery by the positive and negative electrode, electrolyte and polymer separation membrane composition, divide the Department of Li-ion materials technology, the highest barriers to a high-value-added material, gross profit margin is usually 70% or more, accounting for the cost of lithium batteries 20-30 %. Isolating film lithium-ion battery commonly used polypropylene (PP), polyethylene (PE) single-layer microporous membrane, as well as PP and PE by the multi-layer composite microporous membranes as a separation membrane, polypropylene, for example, its raw material cost of about eight thousand dollars / ton, but will its processing into a membrane, its value can be up to 300 yuan / ton, a substantial appreciation of the several hundred times dell Inspiron 1300 battery, dell Inspiron 1420 battery. From the exterior point of view, it is an ordinary white plastic no significant difference, but in the structure of lithium batteries, the diaphragm is one of the key components of the inner layer. Membrane performance, a direct impact on the battery capacity, cycle performance, and security features such as. Fosugufen Chief Engineer, Jin Hui, chairman WU Yao Kan pointed out that as a high technological content, divide the last localization of lithium battery products, and now has mastered the film's core technology. At present, the domestic annual demand is about 130 million square meters, while Jinhui company to 1,200 million square meters. According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting Report" points out that by 2012, if the formation of one million hybrid vehicles the size of the battery separator need nearly 400 million square meters, while the current domestic divide the total production capacity is only 130 million square meters. Future power battery is likely to be double-type growth, their needs will be 10 times more cell phone battery. Polymer film in the thin-film solar cells with a wide range of applications in the same space, development and production of lithium battery separation film, solar photovoltaic system for the new material is a film company in the general direction of industrial upgrading. However, domestic enterprises can produce only a handful of membrane, leading to have been subject to foreign dell Inspiron 1501 battery, dell Inspiron 1520 battery imports, high prices, it is lithium a major cause of high production costs, of course, affect the application of lithium, one of the important reasons. At present, the domestic companies able to produce membrane only star-source technology, Jinhui High-Tech 2 technology is relatively mature market, a serious shortage of supply, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Membrane with a typical "high-tech, high-capital" characteristics, and the project cycle is very long, the investment risk greater enthusiasm for investing in domestic enterprises is not high. Expected global demand for polyethylene, polypropylene and aromatics and other major demand for petrochemical products will be higher than the global GDP2-3% rate of growth, while the fastest growth rate in Asia. To this end, the world's leading petroleum and petrochemical companies, ExxonMobil Chemical is actively investing in order to meet this growing demand. Through the ongoing construction of a joint venture in Fujian, China and the construction of new petrochemical plant in Singapore to make it a world-class petrochemical plant of the increase in production capacity more than doubled. Meanwhile, Saudi Arabia and Qatar is also to promote large-scale investment projects, and in Korea, the construction of a new lithium battery separator plant. Although the development of lithium power industry divide on the promotion of great significance, but from investment point of view statement, diaphragm with a typical "high-tech, high-capital" characteristics, and the project from start to production operation cycle is very long, greater investment risk, to a certain extent hindered of domestic enterprises in this important area of investment dell Inspiron 1525 battery, dell Inspiron 1526 battery. |
