What raw materials production of lithium battery mainly used?

Source: 2020 - 04 - 02 13:05 hits: once you know which raw material production of lithium batteries mainly use lithium battery data constitute the first: the data of positive and negative data, clearance, electrolyte. Temporarily in the positive data is the most used data lithium cobalt oxide, lithium manganese acid, lithium iron phosphate and three metadata ( Nickel cobalt manganese polymers). 。 The positive data accounts for a significant proportion ( The quality of the positive and negative data 4:1 ratio of 3:1 ~) Because the positive function of data directly affect the function of lithium ion battery, its cost is also directly choose the battery costs bump. 2. In negative data temporarily, now the main negative data with natural graphite and artificial graphite. Negative data including nitrides, PAS, tin oxide, tin alloy, nano negative data, and other intermetallic compounds. Negative data as one of four major part of the lithium battery, battery capacity and circulation function for travel plays an important role, is the core of the lithium battery industry. 3. Barriers to market first is PE material ( Polyethylene, polyethylene) And polypropylene ( Polypropylene, polypropylene) The polyolefin ( Polyolefin) Class barriers. In the structure of the lithium battery, the diaphragm is one of the key internal components. Diaphragm effect determines the interface structure and the internal resistance of the battery, directly affect the capacity of the battery, circulation and security features. 4. Electrolyte by organic solvent, lithium electrolyte salts commonly, necessary additives made from under certain conditions in a certain proportion. Electrolytes in lithium batteries to play the role of a conductive ions between the positive and negative, is the lithium ion battery can obtain high voltage and the ratio of assurance. Extended information 'lithium batteries', is a kind of anode materials for lithium metal or lithium alloy, using nonaqueous electrolyte battery solution. Lithium battery can be roughly divided into two kinds: metallic lithium battery and lithium ion batteries. Do not contain metallic lithium, lithium ion battery can charge. Fifth generation rechargeable lithium battery was born in 1996, its safety, specific capacity, self-discharge rate and the function ratio are better than that of lithium ion batteries. Due to its high technical requirements, at present only a few countries a few companies in the production of lithium batteries. Manganese dioxide as positive pole data commonly used lithium batteries, lithium metal or its alloy metal with negative data, using nonaqueous electrolyte solution.
