Abstract:
The purpose of the present embodiment is to provide a lithium secondary battery which is assumed to be operated at a high voltage or to be used at high temperatures for a long period of time, and which has improved life characteristics by suppressing a decomposition reaction of the electrolyte solution. The present embodiment relates to an electrolyte solution for a secondary battery containing a sulfone compound, a fluorine containing ether and an acid anhydride at a specific composition, and a secondary battery which uses this electrolyte solution for a secondary battery.
