Use:

Lithium salt of bisfluorosulfonimide can be used as an electrolyte additive for lithium-ion batteries. It can be used in the electrolyte of rechargeable lithium batteries, which can effectively reduce the high and low temperature resistance of the SEI layer formed on the surface of the electrode plate at low temperatures, and reduce the lithium The capacity loss of the battery during placement provides high battery capacity and electrochemical performance of the battery. It can also be used as an electrolyte for a primary battery; it can be used as a polymerization catalyst; it can also be used as an antistatic agent in the industrial field.

Lithium bisfluorosulfonyl imide has the characteristics of good electrochemical stability, good hydrolysis resistance and high conductivity, and can be widely used in electrolytes, especially in power batteries, which can improve the cycle performance and rate performance of power batteries.
