PROBLEM TO BE SOLVED: To provide an electrolyte for a secondary battery, capable of improving charge/discharge cycle characteristics of the secondary battery, especially the cycle characteristics under high temperature.SOLUTION: There is disclosed an electrolyte for a secondary battery that is characterized by containing: a sulfone compound represented by following formula (1); and a thiophene compound. In the formula (1), Rand Rare each independently a substituted or unsubstituted alkyl group. A carbon atom of Rand a carbon atom of Rmay form a cyclic structure by being bonded to each other through a single bond or a double bond. |
