Lithium bis(trifluoromethanesulfonyl)imide
chemical compound
Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) s a hydrophilic salt. Its chemical formula is LiC2F6NO4S2.[1] It is commonly used as a source of lithium ions in electrolytes for lithium-ion batteries. It is an alternative to the commonly used lithium hexafluorophosphate. It is made up of one lithium cation and a bistriflimide anion.[2] LiTFSI is toxic if swallowed. It is toxic in contact with skin and can cause severe skin burns. Therefore, sealed batteries must not be opened.
