| Hazard Information | Back Directory | [Chemical Properties]
White to Almost white powder to crystal with Molecular Crystal Electrolytes with High Lithium Ion Conductivity. | [Characteristics]
Lithium bis(fluorosulfonyl)imide(LiFSI) is a important high-performance electrolyte material in new energy devices such as lithium-ion batteries and supercapacitors. It has the advantages of high stability (no decomposition below 200°C), excellent low temperature performance, good hydrolytic stability and environmental friendliness, etc., as the next generation of lithium hexafluorophosphate electrolyte lithium salt for secondary lithium ion batteries. | [Uses]
Lithium Bis(fluorosulfonyl)imide is a useful research chemical. | [Preparation]
Lithium bis(fluorosulfonyl)imide (LiFSI) was synthesized by a metathesis reaction between KFSI and LiBF4 in DMC in nearly quantitative yield, similar to the preparation of its analogue, lithium (fluorosulfonyl) (pentafluoroethanesulfonyl)imide (LiFPFSI).
