Electrolyte solution for secondary battery and secondary battery using the same

The present invention provides a technology of inhibiting the decomposition of the solvent of the electrolyte solution for a secondary battery. Further, the present invention provides a technology of prohibiting the resistance increase of a secondary battery and improving the storage properties such as improving the capacity retention ratio. An electrolyte solution 15 comprising non-proton solvent and cyclic sulfonic ester including at least two sulfonyl groups may be used.
