摘要：
[PROBLEM]
To provide: a novel non-aqueous electrolytic solution which uses a methylenebissulfonate derivative, reduces initial irreversible capacity of a battery, and further improves battery characteristics such as cycle characteristics, electric capacity and storage characteristics; a method for producing the non-aqueous electrolytic solution; and a battery which uses the electrolytic solution.
[SOLUTION]
The present invention relates to the following to .
A non-aqueous electrolytic solution comprising the following (1) to (3).
(1) a non-aqueous solvent comprising at least one selected from a cyclic carbonate ester, a straight chained carbonate ester and a cyclic carboxylic acid ester,
(2) a lithium salt which may be dissolved in the non-aqueous solvent, as an electrolyte salt,
(3) a methylenebissulfonate derivative represented by the general formula [I]:
A method for producing a non-aqueous electrolytic solution, characterized by dissolving a lithium salt in a non-aqueous solvent, and then dissolving the methylenebissulfonate derivative.
A non-aqueous electrolytic solution battery provided with (i) the non-aqueous electrolytic solution according to the above , (ii) a negative electrode, (iii) a positive electrode and (iv) a separator.
