Lithium bistrifluoromethylsulfonimide is a white crystal or powder that has good thermal stability and begins to decompose when heated to 360 ° C. It has high electrochemical stability and conductivity, and has corrosion effect on aluminum collector at high voltage (above 4.2V). Therefore, it is often used as a lithium ion battery, organic electrolyte lithium salt. As a high-end additive for lithium battery electrolyte, it can improve the electrochemical performance and stability of the electrolyte, thereby improving the overall performance of lithium battery.
