Is well known that the production of lithium batteries may divide separator, electrolyte and cathode, anode 4 sub-sectors have accounted for these materials, lithium batteries cost 40% to 46%, 10% ~ 14%, 5% ~ 11% and 5% to 15%.

According to experts, the membrane technology is the lithium content of materials products with high added value, the highest gross margin of 70%. substantive effectiveness of the membrane a direct impact on the battery capacity, cycle and safety features such that there are still no society can produce, including BYD, including all imported. It is reported that the production of small lithium batteries separator Fosugufen undertaken 863 projects membrane technology R & D tasks.

Electrolyte lithium-called “blood” is a lithium battery for high voltage,Sony VGP-BPL8 , VGP-BPS8, high specific energy and other benefits of the guarantee, Jiangsu Cathay Pacific is the first company producing the electrolyte, the company is R & D by a foreign monopoly of lithium hexafluorophosphate draft synthesis technology, the production of lithium hexafluorophosphate electrolyte is an electrolyte important key imported. lithiumfluorophosphate electrolytes are the basic raw 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, Morita, chemical and several Japanese companies a monopoly.

Domestic production is the subject of many enterprise level, but most of the production of lithium cobalt oxide, lithium manganese oxide, etc., the actual production of iron phosphate and lithium are not many manufacturers. Lithium iron phosphate material to make it easier for lithium-ion high capacity used in tandem to meet the needs frequent electric car loading and unloading. In the future trend, with non-toxic, non-polluting, safe performance, wide variety of sources of raw materials, low cost, long life, is the ideal material for the next generation of lithium cathode, will become the leader products are high quality materials VGP-BPS9  battery
lithium anode, the anode materials of graphite carbon for its wide variety of sources, cheap, has been the main types of anode materials
