OVERVIEW

English name: Lithium Bis(fluorosulfonyl)imide

CAS No.: 171611-11-3

Molecular formula: F2NO4S2. Li

Molecular weight: 187.0721064

EINECS No.: 686-526-7

Summary:

Due to its high stability (no decomposition below 200 ℃), excellent low-temperature performance, good hydrolysis stability and more environmentally friendly, lithium difluorosulfonate (LiFSI) can be used as the lithium salt of the next generation secondary lithium-ion battery electrolyte to replace lithium hexafluorophosphate.

Applications:

Lithium difluorosulfonamide has the characteristics of good electrochemical stability, good hydrolysis resistance and high conductivity. It can be widely used in electrolyte, especially in power battery, which can improve the cycle performance and rate performance of power battery.

Properties

Bifluorosulfimide lithium salt can be used as the electrolyte additive of lithium-ion battery and applied to the electrolyte of rechargeable lithium battery. It can effectively reduce the high and low temperature resistance of SEI layer formed on the surface of electrode plate at low temperature and reduce the capacity loss of lithium battery during placement, so as to provide high battery capacity and electrochemical performance of battery, It can also be used as electrolyte for primary battery; It can be used as polymerization catalyst; It can also be used as antistatic agent in industrial field.
