An electrolyte composition includes: a sulfonylimide compound represented by the following general formula (1) as an electrolyte salt; and an amidosulfuric acid component.LiN(XSO)(XSO)  (1)

Electrolyte composition, solvent composition, non-aqueous electrolyte, and use thereof

In the present invention, a bis (fluorosulfonyl) imide metal salt is an alkali metal salt of bis (fluorosulfonyl) imide or an alkaline earth metal salt of bis (fluorosulfonyl) imide. The bis (fluorosulfonyl) imide metal salt has an average particle diameter of not less than 0.1 mm, or has an average moisture absorption rate of not more than 2.5 mass ppm/cm&#xb7;min when sealed in a PE bag having a thickness of 80 &#x3bc;m and left for 30 minutes at 23&#xb0; C. and 65% humidity.

Bis(fluorosulfonyl) imide metal salt and method for preparing same

Provided is a method the enables easy production of bis(fluorosulfonyl)imide suitable for a non-aqueous electrolytic solution for a lithium ion secondary battery, etc. The method for producing a bis(fluorosulfonyl)imide alkali metal salt according to the present invention comprises reacting bis(fluorosulfonyl)imide with an alkali metal compound in a reaction solution containing an organic solvent, wherein the organic solvent includes at least one organic solvent (A) selected from the group consisting of carbonate solvents, cyclic ether solvents, linear ether solvents having two or more oxygen atoms in the molecule, cyclic ester solvents, sulfolane solvents, N,N-dimethyl formamide, dimethyl sulfoxide, and N-methyl oxazolidinone.
