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.

Claim (Index 4):
The electrolyte solution for a secondary battery according to  claim 1 , wherein the fluorine-containing ether compound represented by formula (2) is at least one selected from 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether, 2,2,3,4,4,4-hexafluorobutyl-difluoromethyl ether, 1,1-difluoroethyl-2,2,3,3-tetrafluoropropyl ether, 1,1,2,3,3,3-hexafluoropropyl-2,2-difluoroethyl ether, 1,1-difluoroethyl-1H,1H-heptafluorobutyl ether, 1H,1H,2\u2032H,3H-decafluorodipropyl ether, bis(2,2,3,3,3-pentafluoropropyl) ether, 1H,1H,5H-perfluoropentyl-1,1,2,2-tetrafluoroethyl ether, bis(1H,1H-heptafluorobutyl) ether, 1H,1H,2\u2032H-perfluorodipropyl ether, 1,1,2,3,3,3-hexafluoropropyl-1H,1H-heptafluorobutyl ether, and 1H-perfluorobutyl-1H-perfluoroethyl ether, bis(2,2,3,3-tetrafluoropropyl) ether.
