China has become second only to Japan in the production of lithium-ion battery power, in the next few years will be material, technical, technological and equipment, and made breakthrough progress, “auto level” of lithium-ion Hp battery will enter the mass market, is about to serve the fast The development of the electric vehicle industry.
The development of electric vehicles to reduce oil consumption and reduce vehicle emissions of vehicles the best way is in a stage of rapid development of lithium-ion batteries for electric vehicles is about the development of the industry to prepare. The lithium-ion battery anode is a lithium storage materials, is positive with the lithium-transition metal compounds LiCoO2, LiMn2O4, LiFePO4, and so on, a lithium salt electrolyte solution or an organic polymer. Compared with other batteries, lithium-ion battery with a high-voltage, high-energy, charging and discharging a long life, no memory effect, pollution-free, fast charging, low self-discharge rate, temperature and a wide range of safe and reliable, and other advantages of battery life / cost Than being further enhance the application of lithium-ion batteries for electric vehicles using the cost will be lower than gasoline cars, electric model will be used for the use of low power and charging for a long time to overcome the shortcomings of the electricity for businesses and easy-to-vehicle drivers take

Manufacturers are taking place in the way of change
At present, lithium-ion battery industry is undergoing major structural adjustment, the auto industry demands for lithium-ion ASUS battery life than the small battery for more than twice as long, costs down 50%, more than 10 times the Monomers capacity, to increase production or even dozens of Thousands of times. Battery manufacturers involved in the selection and evaluation of materials, a chip manufacturing, manufacturing batteries, battery management
Manufacturing system and battery pack assembly and a series of processes, the manufacturing process is directly related to the battery of consistency and security. The industrialization of the battery power is accompanied by materials, technology and equipment of a major take-off, the traditional cobalt-oxide cathode materials are being cheaper and better security of the manganese oxide and phosphate-based materials to replace, for The small battery electrode preparation process will gradually be efficient, low power and low emissions technology replaced by a new, large-scale thermal power batteries of high-power and input / out of batteries so that the requirements of design changes accordingly in the material Preparation technology, Latitude D500 battery manufacturing, technology and equipment was constant innovation. Large-scale industrial development of resources and the environment also created challenges, the development of lithium-ion battery recycling technology in order to achieve material recycling has become an urgent task.
Need for a comprehensive security solution
Lithium-ion battery safety incidents is the lithium-ion M8511 battery used in the process of an explosion and fire accidents in the charging process, charging after use and traffic accidents caused by mechanical damage to the battery when it could have happened. Effects of lithium-ion battery safety of the main factors of the A1078 battery electrode materials, electrolytes and the manufacturing process and conditions of use. Abuse battery, controllability does not occur within a chemical reaction and emit heat directly related to lithium-ion battery electrolyte composed of organic carbonate, a low flash point, low boiling point, is extremely strong oxidizing compounds, a very strong negative reduction Compounds, when the heat generated in the battery faster than the speed of heat, it will cause a battery internal pressure caused by the explosion, or the case broke down in contact with air, as a result of high temperature and high negative electrode of lithium lively nature of the fire ignited .
In general, the safety of lithium-ion VGP-BPS8 battery and is stored in inverse proportion to the total energy, electric bicycles used in lithium-ion battery pack for the weight of 3 to 4 kilograms, the largest mobile phone 100 times. With the increase in the capacity of the battery, battery size is also increasing, the cooling performance variation, the possibility of accidents increase. As a result, will be made lithium-ion batteries battery power, it is necessary to improve their safety performance, greater ThinkPad R50 battery single, to meet the requirements of the security indicators also higher.
At first carry out internal lithium-ion battery electric vehicle research and development, there were a number of explosions and burning incident, one of the main reasons is the use of cell phones are usually used as a lithium cobalt acid battery cathode material. In the course of the use of some of the accidents occurred, such as management system and lead to damage to the battery voltage is too high, positive in the remaining part of the lithium electrolyte will emerge as the negative electrode to the surface in the form of lithium metal deposition, and the lithium Electro-deposition on the surface vulnerable to the formation of “dendritic” in order to pierce a lack of communication is the negative short-circuit caused the fire explosion accidents, and so on. In addition, lithium is very lively, has a low melting point, the battery temperature is too high or partially damaged shell contact of the easy-to-air fire. China’s high-power lithium-ion Latitude D820 battery safety of the “Five-Year Plan” period, was a better solution. Use of modified lithium manganese oxide cathode material reduces oxidation, the activity of lithium content than lithium cobalt low. Related to negative, and electrolyte manufacture, use, it is also adopted a series of innovations.
Industrial batteries for electric vehicle industry to prepare
Electric vehicle industry’s urgent need for the development of high-power sony battery battery support, China’s lithium-ion battery technology industries also need to upgrade the development of battery technology. China has become second only to Japan in the production of lithium-ion battery power, highly competitive, broad-coating machines, such as the current lithium-ion battery production equipment have also been critical of China for lithium-ion battery development to lay a good foundation. Through scientific research, engineering and management personnel to work together in the next few years is expected to be in material, technology, processes and equipment, and made breakthrough progress, “auto level” of lithium-ion batteries will enter the mass market, is about to serve the rapid development of the The electric vehicle industry.
