| | Lithium Bis(fluorosulfonyl)imide Usage And Synthesis |
| 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 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).
