Infobox references

Lithium bis(trifluoromethanesulfonyl)imide, often simply referred to as LiTFSI, is a hydrophilic salt with the chemical formula LiC₂F₆NO₄S₂.^[1] It is commonly used as Li-ion source in electrolytes for Li-ion batteries as a safer alternative to commonly used lithium hexafluorophosphate.^[2] It is made up of one Li cation and a bistriflimide anion.

Because of its very high solubility in water (> 21 m), LiTFSI has been used as lithium salt in water-in-salt electrolytes.^[3]^[4]^[5]
