PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic solution excellent in initial capacity and capacity retainability (cycle characteristics).SOLUTION: The electrolytic solution for a nonaqueous secondary battery contains a compound represented by formula (I) and an electrolyte in an organic solvent. (In the formula, Xa represents an alkyl group, an aryl group, an aralkyl group, an acyl group, an alkylaminoacyl group, or an alkyl- or aryl-sulfonyl group, and Ya and Za represent organic groups and may be linked together to form a ring.) |
