Lithium Difluorophosphate (24389-25-1) is a white powder solid with a melting point of 340℃. It can easily absorb moisture in the air and exhibit acidity when exposed to air. It is used as an additive in electrolytes for lithium-ion batteries to enhance the cyclic performance, high-temperature storage performance, and lower the internal resistance of the battery.

Lithium Difluorophosphate, as an additive of electrolyte for rechargeable Lithium-ion battery, effectively reduces the resistance of SEI layer formed on the electrode under low temperature, and reduces self-discharge of the battery. Meanwhile,adding of Lithium Difluorophosphate can reduce the usage of Lithium Hexafluorophosphate(LiPF6).

In the closed steel reaction dad, respectively, P2O5, LiF and dry tetrachlorofuran were added to the reaction dad at room temperature, sealed and stirred, cooled down to -40 ° C, and replaced the kettle atmosphere three times with nitrogen, argon or heliu
