Packing: 20g/bottle.
Material name: Lithium bis(trifluoromethylsulfonyl)imide.
Application: Lithium battery electrolyte material.
1. Lithium bis(trifluoromethylsulfonyl)imide is mainly used in organic lithium batteries and antistatic agents. Due to the strong covalent bond of organic anions, it exhibits excellent thermal stability.
2. Used in the primary lithium battery industry, its conductivity is comparable to that of LiClO4 and LiAsF6, and there is no need to worry about stability and safety. Used as a secondary salt in the electrolyte of secondary lithium batteries, it can effectively improve the performance of the electrolyte.
3. It can also be used as a synthetic raw material for antistatic additive ionic liquids, which are compatible with various high-performance polymer materials, including thermoplastic and thermosetting types.
