Lithium Bis(fluorosulfonyl)imide Structural

What is Lithium Bis(fluorosulfonyl)imide?

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.

The Uses of Lithium Bis(fluorosulfonyl)imide

Lithium bis(fluorosulfonyl)imide is a promising new electrolyte additive for lithium ion batteries showing increased conductivity over LiPF6. Bis(fluorosulfonyl)imide has also been tested in next generation gel polymer electrolytes with improved safety properties.

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).
