Market resistance does not call lithium battery ready to power foot

"Agency Internal Reference" editor's note: New energy vehicles are the future development direction of the automotive industry, lithium batteries as the core power of new energy vehicles, is an important beneficiary of future investment.　　Lithium battery-related stocks will be repeated speculation in the market, the proposed focus on the band to grasp the investment opportunities. Electric vehicles and lithium batteries complement each other as an effective means of stimulating the economy and saving energy and reducing emissions, electric vehicles are becoming the focus of government policy support. It is estimated that a pure electric vehicle needs 40~50 kg of cathode materials and electrolyte, the production of 1 million electric vehicles required lithium-ion battery related materials, will be the current global lithium battery material demand several times.　　Therefore, the promotion of electric vehicles will lead to lithium-ion battery-related materials demand for a burst of growth. Lithium battery, as the core of new energy vehicle, will be the main object of policy support. The breakthrough of lithium battery technology will promote the development of electric vehicle industry in turn.　　In terms of market performance, the lithium-ion battery concept Unit was again hyped this week, showing the market's enthusiasm for lithium-ion batteries. Lithium battery concept stocks investment strategy lithium battery mainly includes positive electrode, cathode, electrolyte and diaphragm in four parts. The cathode material accounted for nearly half of the manufacturing cost, followed by the diaphragm, the 10%~14%, and the negative material accounted for the whole production cost 5%~15%. Diaphragm manufacturing investment rate of return is the highest, nearly 70%, nearly 3 years, the trend is increasing year by decade, positive materials investment rate of return is the lowest, maintained at 17% level.　　Although the benefits are different, but as part of the lithium battery, we analyze the investment opportunities of lithium battery plate from the structural point of view. 1, cathode material is the key factor to determine the performance of electric vehicles. Electric vehicles require batteries with high energy, large power, self-discharge small, low price, long service life and good security characteristics, the corresponding cathode materials must meet the same requirements. The cathode material industry has an annual growth rate of about 15% in the past 10 years, which belongs to the high growth industry.　　2009 global sales of lithium-ion battery materials rose 16.2%, up to 3.39 billion U.S. dollars, of which the positive material sales value of about 1.81 billion U.S. dollars. At present, the most mature, widely used and commercially successful lithium-ion battery cathode material is cobalt acid lithium, but it has the disadvantage of high cost and low safety. In the field of power battery, lithium manganese oxide and lithium iron phosphate are the most promising cathode materials, which have a stronger price advantage and better thermal stability and safety.　　In the stock, it is recommended to focus on the current occupation of the largest positive material market share of the technology, the domestic production of lithium manganese, Citic Guoan, as well as the richest battery products desay battery. 2, anode materials at present, commercial lithium batteries are basically used as carbon materials to do the negative, mainly including graphite carbon materials, amorphous carbon materials, nitride, silicon-based materials, tin-shaped materials, new alloys and so on. The anode material technology is mature, the domestic already realizes the industrialization, basically can satisfy the domestic market demand, the domestic industry top three is deepChun Betry, Shanghai Shanshan, Changsha Hairong. Shenzhen Betry is a subsidiary of China Bao ' an group holding 55%, is the domestic battery carbon anode material standards, as of July 2010, its carbon anode capacity of more than 7000 tons, global market share of 12%, ranked fourth in the world.　　Therefore, the stock proposal focuses on Bao ' an, China. 3, electrolyte electrolyte, including solvents and electrolytes, is to achieve the transfer of lithium ions in the positive and negative media, the lithium capacity, operating temperature, cycle efficiency and safety have important effects. The electrolyte additive becomes the hot spot under the condition that the main solvent is more definite.　　In recent years, the increasing variety of additives, the role of electrolyte increasingly highlighted, promoting the increase of electrolyte varieties and performance promotion, in the future of the field of lithium power, additives will play a greater role. Electrolyte is an essential component of lithium electrolyte, which has good conductivity and electrochemical stability, and is the current mainstream electrolyte. At present, the synthesis technology of lithium hexafluorophosphate is mainly in Japanese enterprises, and there is still a gap between the product quality and the international advanced level in China. From the progress of the future, we will be able to achieve a breakthrough in the lithium hexafluorophosphate, and basically in the current into the pilot enterprises in the production.　　It is recommended to focus on the transition from the pilot to industrialization of more than fluorine, and is conducting pilot in the domestic electrolyte leader Jiangsu Guotai. 4, diaphragm lithium battery diaphragm has a separate positive and negative, to prevent the role of short circuit, while allowing the lithium ion through to form a charge-discharge circuit, so the battery diaphragm should have good insulation, small resistance, good chemical stability. At present, China's production of battery diaphragm thickness and aperture uniformity and a large gap abroad, the need for the domestic diaphragm 80% still need to import, the existing production equipment for Low-cost single-layer polyolefin tensile diaphragm production line, the main supply in the low-end market. The company is concerned about the production of the battery diaphragm of the Buddha-plastic shares.
