Demand for lithium battery as expanding the application areas and increasing year by year. At present, the lithium battery has gradually to develop the field of electric bicycle, electric vehicles and so on. Is already the low carbon economy era, our country in the new energy and energy conservation and emissions reduction has made rapid development, lithium ion batteries with high energy, and is more environmental protection, has been fully replace the traditional lead-acid, nickel-metal hydride and nickel cadmium battery, become the 21st century is the most important energy storage component, horizontal speed of the development of technology will directly affect the whole new energy industry development speed and quality. With the upcoming series of new energy vehicles supporting policy, China's new energy vehicles will be rapid development during the "twelfth five-year", will drive the rapid growth of lithium-ion battery industry, and to develop satellite, aerospace and energy storage. At the same time, along with HEV hybrid electric vehicle, the development of 3 g mobile phone and other electric tools, a rapid rise in domestic lithium rechargeable batteries market share, domestic lithium electricity enterprises have huge market growth space.
　　It is understood that this kind of high security, high reliability, high performance lithium battery service life can reach more than 4 years. In addition to the application in pure electric and hybrid bus outside, also can be widely used in ships, engineering machinery, rail transportation, wind, solar, mobile base stations, power and bank, etc.
　　Chinese companies have stepped up all kinds of resources, such as increasing the automation or half automation equipment, production pattern from the labor-intensive to semi-automatic and automatic transformation, development of independent innovation technology, perfect quality system, product quality and labor productivity through ascension, the high-end market and high-end product development, has become the current trend of the development of China's lithium battery industry.
　　Lithium battery is mainly composed of four parts, respectively for electrode, electrolyte, diaphragm and packing materials. At present domestic packaging materials and graphite anode technology is relatively mature, the cost of proportion is not high. The core of the lithium ion battery materials mainly is the positive electrode material, electrolyte and diaphragm. 30% of the anode materials for lithium battery costs, electrolyte and diaphragm costs accounted for 10% and 20% respectively.
