Li-polymer battery car application
“Lipo Battery”,it is a kind of anode material made of lithium metal or lithium alloy,use a battery in a non-aqueous electrolyte solution. GilbertN Lewis put forward and study lithium metal battery in 1912,then lithium ion batteries were proposed and studied by M.S.WhitTIngham in 1970s . Lithium is very reactive because of its chemical properties,so that makes the processing, preservation and use of lithium metal very high environmental requirements,that’s why lithium batteries have not been used for a long time. With the development of science and technology, lithium battery has become the mainstream.
Lithium battery mainly classified into two types：Lithium metal battery and Li-ion battery.Li-ion batteries don’t contain metal lithium,and it’s rechargeable.The rechargeable fifth generation of rechargeable battery was Born in 1996,it’s safety, specific capacity, self-discharge rate and performance cost ratio are better than previous.Limited by it’s own high - tech requirements,now only a few countries producing the lithium metal batteries.
Li-on batteries are an alternative to the lithium metal batteries that emerged in previous years,The main components of the battery are anode and cathode, electrolyte, diaphragm and shell.
Positive pole---Use carbon poles that can trap lithium ions,Lithium becomes lithium ions when discharge, break away from positive,reach the lithium-ion battery cathode.
Negative pole----The material is selected as close to lithium potential as possible embedded lithium compounds,eg, various carbon materials include natural graphite, synthetic graphite, carbon fiber, intermediate phase carbon and metal oxide.
Electrolyte---A mixed solvent system of ethylene propylene carbonate and low viscosity diethyl carbonate.
Diaphragm---Use polyene microporous membranes such as PE, PP or their composite membranes,in particular, PP/PE/PP three-layer diaphragm has a low melting point,and it has high puncture resistance,that’s heat insurance
Shell---Use steel or aluminum,The cover assembly has the function of explosion-proof power cut off.
