Be constantly progressive, the requirement to performance of lithium ion battery is higher and higher.Exploitation high-energy density widens battery using temperature model
Enclose, improve the problems such as battery safety to vast Study on Li-ion batteries person propose stern challenge.It is generally acknowledged that in lithium
During ion battery first charge-discharge, electrode material and electrolyte react on solid-liquid phase interface, and electrolyte occurs
Reduction is decomposed, and one layer of passivation layer for being covered in electrode material surface is formed.This passivation layer is a kind of boundary layer, is that electronics is exhausted
Edge body is the excellence conductor of Li+, and Li+ freely can be embedded in and deviate from by the passivation layer.The film contain Li2CO3,
The various organic principles such as the various inorganic constituents such as LiF, Li2O, LiOH and RO- CO2Li, ROLi, (ROCO2Li) 2, thickness
Heterogeneous film from tens nanometers to several hundred nanometers.Excellent passivating film can improve the cycle efficieny and reversible capacity of battery
Etc. performances.Therefore, a small amount of Cucumber is added in Organic Electrolyte Solutions for Li-Ion Batteries, can preferentially be gone back on Carbon anode
Passivating film that is former, being decomposed to form function admirable, so as to improve the performance of Carbon anode, these micro substances are referred to as film forming and add
Add agent.
