The Lithium battery unit

Currently, the development of lithium-ion laptop battery shows the situation in several directions simultaneously. The main difference is the direction of the cathode material used in the different. In all cathode materials in lithium battery, the materials used for main power batteries are lithium manganese oxide, the three elements of three types of materials, iron phosphate and lithium laptop battery.

Interior materials of lithium dell battery cathode listed companies related to mining in Tibet, Shanshangufen, CITIC China Baoan, etc. Ann. Among the upstream mining in Tibet has advantages of raw materials, the company Zhabuye Salt Lake (proven reserves of over 2 million tons of lithium carbonate) 20 years of mining rights.

CITIC Guoan UNITA controlled CITIC strong company profits since 2002, has undertaken a “lithium-ion battery cathode material – manganese lithium technology development industries,” “industrialization pure battery electric vehicle lithium-ion R & D” so large projects. CITIC Guoan also developing lithium battery materials, resources, development and production of Qinghai national security is the key raw materials, cathode materials of lithium carbonate lithium. Although the company’s production of lithium Dell Studio 14 batterycarbonate is also only a few thousand tonnes, but the design capability of the company 25,000 tons / year, the potential for future development.

Shanshangufen was built from the anode to the cathode, the electrolyte of a complete system. In the cathode material, the company has become the third largest global supplier of cathode materials. A mastered the preparation of iron phosphate and lithium.

China Baoan caused the initial struggle of the whole chain of the materials industry is the battery cathode material lithium iron phosphate, setting the standard. Bei Terui the company that owns 55% of the iron company cathode material lithium phosphate production capacity has reached 1,500 tons / year, representing 75% of the hardware business ternary Tianjiao main cathode in 2008 the first sales at home and share national market 30% to 40%.

Also, is the first volume Shanshangufen CMS (mesophase carbon microbeads) from domestic producers, the current annual capacity of 1,200 tons. In artificial graphite and natural graphite anode materials such as carbon system has a strong field intensity.

performance electrolyte lithium battery is another important influence material, representing about 12% of the cost of lithium batteries. lithiumfluorophosphate which is at the heart of electrolyte materials, which represents approximately 50% of the cost of the electrolyte. As production of technical difficulty is very high in the international arena of the electrochemical industry, SUTERAKEMIFA, Morita, chemical and several Japanese companies a monopoly. Tianjin, China currently only has a capacity of 80 tons Taurus, and all for personal use. Jiangsu Guotai (002091, IT stocks) owned Huarong Chemical is currently the manufacturer of the largest and highest grade of the lithium battery electrolyte. The company is building, “300 tons of lithium hexafluorophosphate project. Shanshangufen their electrolyte Dongguan Shanshan is the second largest producer, currently has an annual capacity of around 1,500 tonnes of electrolyte. Current supply the world market and application of the electrolyte and cathode material, are mainly based on the market for lithium batteries stock market depends on the next increment of market power lithium batteries.

In addition, the lithium battery in the field of energy reserves have important applications, first of all solve the problems of adjusting the energy of the valley. Second, clean energy resources like wind, solar and tidal energy are intermittent equipment lithium energy storage and use of clean energy production electricity, energy storage, energy released during the break, can alleviate the energy shortage in China status.
