Abstract:

Due to their unique structure and performance，bis（fluoro-based sulfonyl）imides and their salts have attracted increasing interests in the fields of lithium-based rechargeable batteries，ionic liquids，and catalysts，et al. In this paper，preparation methods of these compounds are reviewed，and their advantages and disadvantages are compared. The reason of some alkali metal salts combined with hydration water is analyzed from their molecular structures，and preparation methods of anhydrous alkali-metal salts are also summarized. Their performance is introduced when they are used as electrolytes of lithium-based rechargeable batteries. At last，their application progress is presented，and the research emphases and development trend are discussed.
