The invention provides a preparation method of a bis-trifluoro sulfonimide salt. The method comprises the following steps of S1, preparing corresponding N-alkyl-substituted bis-trifloromethane sulfonimide with primary amine and trifluoromethyl sulfonic anhydride; S2, reacting the N-alkyl-substituted bis-trifloromethane sulfonimide with a salt to obtain a crude product; S3, crystallizing the crudeproduct and then drying the crude product in vacuum to obtain the bis-trifloromethane sulfonimide salt. The method has the advantages that N-alkyl-substituted bis-trifloromethane sulfonimide is stablein property and does not generate corrosive substances in a whole reaction process, three wastes are hardly generated, the method is suitable for large-scale production, the high-purity battery-gradebis-trifloromethane sulfonimide salt can be obtained, and a high implementation value and considerable social and economic benefits are acquired.

Numerous salts of the (CF3SO2)2N- anion, called TFSI, were prepared according to an original one-pot procedure. First, N-benzyl trifluoromethanesulfonimide (N-benzyl triflimide) was treated with ethanol to form
N-FLUORO-BIS(TRIFLUOROMETHANESULFONYL)IMIDE AN IMPROVED SYNTHESIS

, p. 7 - 12 (2007/10/02)
An improved synthesis of (CF3SO2)2NH and its conversion to the very useful fluorination reagent (CF3SO2)2NF is described.The five-step synthesis yields (CF3SO2)NF in 76percent yield based on the starting CF3SO2F.
