Abstract
An electrolyte composition includes: a sulfonylimide compound represented by the following general formula (1) as an electrolyte salt; and an amidosulfuric acid component. LiN(X1SO2)(X2SO2) (1) (where X1 and X2 are identical to or different from each other, and each represent a fluorine atom, an alkyl group with a carbon number of 1 to 6, or a fluoroalkyl group with a carbon number of 1 to 6).
Claims22
An electrolyte composition comprising:
- a sulfonylimide compound represented by general formula (1) as an electrolyte salt,

- and
- an amidosulfuric acid component comprising at least one or more of amidosulfuric acid and a salt thereof, an amidosulfuric acid derivative and a salt thereof represented by general formula (4),
- wherein the general formula (4) is R1R2NSO2 (OM), where R1 and R2 each represent a hydrogen atom, an alkyl group with a carbon number of 1 to 10, a cycloalkyl group with a carbon number of 3 to 10, an aryl group with a carbon number of 6 to 16, an aralkyl group with a carbon number of 7 to 16, or an alkanoyl group with a carbon number of 2 to 16,
