Lithium bis(fluorosulfonyl)imide overview：
Lithium bisfluorosulfonimide (LiFSI) has the advantages of high stability (no decomposition below 200°C), excellent low-temperature performance, good hydrolysis stability and more environmental friendliness, and can be used as a next-generation secondary lithium ion battery to replace lithium hexafluorophosphate Electrolyte lithium salt.
Lithium bis(fluorosulfonyl)imide application：
Lithium bisfluorosulfonimide salt can be used as an electrolyte additive for lithium-ion batteries and used in the electrolyte of rechargeable lithium batteries. It can effectively reduce the high and low temperature resistance of the SEI layer formed on the surface of the electrode plate at low temperatures. The capacity loss of lithium batteries during the placement process provides high battery capacity and battery electrochemical performance. It can also be used as an electrolyte for primary batteries; it can be used as a polymerization catalyst; and it can also be used as an antistatic agent in the industrial field.
Lithium bis(fluorosulfonyl)imide purpose：
Lithium bisfluorosulfonimide has the characteristics of good electrochemical stability, good hydrolysis resistance and high conductivity. It can be widely used in electrolytes, especially in power batteries, which can improve the cycle performance and rate performance of power batteries.
