Lithium Bis(fluorosulfonyl)imide 171611-11-3

Introduction:

Lithium Bis(fluorosulfonyl)imide is a white to off-white powder. It has the advantages of high stability (no decomposition below 200°C), excellent low-temperature performance, good hydrolysis stability and more environmentally friendly.

Specification:

Application:
Lithium bis(fluorosulfonyl)imide (LiFSI) is mainly used as an electrolyte additive for lithium-ion 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, reduce the capacity loss of lithium batteries during storage, and thus improve the battery capacity and electrochemical performance.
The defect of this product is that it is easy to corrode the aluminum current collector, but another additive LiBOB can be added to the electrolyte system to effectively inhibit the corrosion of LiFSI on aluminum foil, and LiFSI can significantly reduce the high impedance of LiBOB. Therefore, the LiFSI/LiBOB composite additive can significantly improve the rate performance and cycle performance of lithium-ion batteries. It can also be used as a primary battery electrolyte, polymerization catalyst, and antistatic agent.
