Characteristics of LiTFSI as conducting salt in electrolytes

Lithium bis(trifluoromethanesulfonyl)imide is a promising alternative to lithium hexafluorophosphate due to its superior thermal and chemical stability, including a reduced sensitivity towards hydrolysis. However, the inability of LiTFSI to form a protective layer on the aluminum current collector, preventing its anodic dissolution at high potentials, limits its use as single salt. LiTFSI is highly soluble in water and organic solvents and therefore, can be used to produce water-in-salt electrolytes for aqueous lithium-ion batteries or highly concentrated electrolytes, respectively. Due to its high thermal stability LiTFSI can be applied in high-temperature electrolytes.
