Abstract
An electrolytic solution capable of improving battery characteristics even at high temperature, and a battery using the electrolytic solution are provided. A separator is impregnated with an electrolytic solution. The electrolytic solution includes a cyclic imide salt such as 1,1,2,2,3,3-hexafluoropropane-1,3-disulfonimide lithium and a light metal salt such as difluoro[oxalato-O,O'] lithium borate or bis[oxalato-O,O′] lithium borate. Thereby, the decomposition reaction of the electrolytic solution can be prevented even at high temperature, and the battery characteristics can be improved.
