CAS NO:90076-65-6 LiTFSI/Lithium Bis(trifluoromethanesulfonimide)

It is an imide-based lithium salt, characterized by: extremely high solubility, self-dissolving after absorbing water, slow hydrolysis rate, high temperature resistance, and corrosiveness to the current collector under certain voltages. And could provide high-purity electrolyte materials, ensuring excellent ionic conductivity and electrochemical stability.

A.It can improve the conductivity of the electrolyte and, as a small amount of additive, enhance the low-temperature performance of the electrolyte.
B.The excellent dispersion ability and stability of LiTFSI in polymers make it useful in polymer-based electrolytes and in research on some solid-state electrolytes.
C.As a hydrophilic organic salt, it has numerous applications in electronic and electrical systems.
D.Another important property of LiTFSI is its extremely high solubility in water: 21 mol/L or ≈6 kg/L. Due to its high solubility, LiTFSI has been studied as an electrolyte for lithium-ion batteries, solar cells, and similar applications.

LiTFSI is mainly used to solve the performance degradation and safety problems of lithium batteries under high voltage and low temperature extreme conditions.

With the increasing use of lithium batteries in new energy vehicles, the gradual application of new electrolyte additives and solid-state batteries, and the accelerated release of demand, the demand for LiTFSI will further increase.

LiTFSI must be particularly cautious about moisture prevention during use and storage because it is highly susceptible to moisture absorption, and when it absorbs moisture, it will react with water to form corrosive and toxic hydrogen fluoride, which will cause its performance to decline and affect the safety of the battery.
