Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. The electrolyte lithium hexafluorophosphate main raw materials, 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%, however, the market power basically Kanto chemical industry, SUTERAKEMI-FA, Morita chemistry, several Japanese companies a monopoly. Department of lithium material diaphragm highest technical barriers to a high value-added materials, usually over 70% gross profit margin, accounting for a lithium battery costs 20 to 30%. It is reported that a car needs from 1000 to SONY NP-FM50 Battery SONY NP-F550 Battery SONY NP-F330 Battery CANON BP-511 Battery CANON BP-512 Battery 2000 square meters of membrane. At present, a serious shortage of market supply of the diaphragm, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard control. The domestic energy production and membrane only star-source technology, Jinhui Tech two technologies are relatively mature. Automobile manufacturers based on the safety of people-oriented concept, the safety of the battery made a very high demand. As the work vehicle battery voltage is 12V or 24V, single power lithium-ion battery voltage is 3.7V, so multiple cells must be used in tandem, but difficult to achieve because the battery charge and discharge completely homogeneous, resulting in the battery charge will appear discharge imbalance, which appeared inadequate charging and over-discharge phenomenon, this situation will lead to a sharp deterioration in battery performance, leading the entire group of cells does not work, or even scrapped, significantly affect battery life and reliability. Therefore, power lithium-ion battery to get a good application, need materials, batteries, management systems, taking into account other aspects of machining. Therefore, the upstream and downstream enterprises should work together to battery as the core of the material, the management system requests formation of an industry group that help to technological progress and system costs.CANON BP-508 Battery CANON BP-2L5 Battery CANON BP-2L12 Battery -------------------- Middle materials manufacturers continue to realize the localization and improvement of technical High barriers to entry lithium battery cathode material, the minimum capacity; anode materials has been achieved the domestic industry; electrolyte and membrane technology is still dependent on imports. Li-ion battery electrode materials can be divided into two (positive / negative) materials,dell Latitude C610 battery, dell Latitude C640 battery, dell 1691P battery, dell 75UYF battery, separator and electrolyte. Lithium battery cathode material is the core of the current lithium cobalt oxide, lithium manganese oxide, lithium nickel-cobalt-manganese-based lithium iron phosphate. Zeyi graphite anode materials, carbon-based solid; in the middle of the positive and negative is the battery electrolyte and separator. As barriers to entry high capacity cathode materials for lithium batteries is the smallest, which is the whole industry chain, dell 1691P battery, the most promising aspect. The current production of cathode material companies are: China Baoan, CITIC Ann Shanshangufen, BYD.Laptop BatteryACER Laptop Battery Dell Laptop Battery Compared with the cathode material, anode material graphite, solid carbon, accounting for the proportion of low cost lithium batteries, and the domestic industry has been achieved. Currently engaged in the production of lithium battery anode materials enterprises in China before the three national security, Shanshangufen, long sand sea capacity. It should be noted that, although the underlying anode material is currently able to meet the needs of the domestic market, but with the increasing popularity of new energy vehicles, the future market demand for this piece of a huge gap.
