New process of bis-trifluoro sulfonimide salt

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.

A simple access to metallic or onium bistrifluoromethanesulfonimide salts

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

MOLTEN SALT COMPOSITION AND USE THEREOF

Molten salt compositions comprising two or more types of molten salts (MTFSI) containing imido anion (TFSI) as an anion and alkali metal (M) as a cation exhibit a lowered electrolyte melting point and an enlarged operating temperature range as compared with those of single salts. Therefore, various advantages, such as enlarging of the range of material choice in the use in battery, etc., can be brought about.
