    • To provide: a novel non-aqueous electrolytic solution which uses a methylenebissulfonate derivative, reduced 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 related 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 [1]: 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.
