| 摘要 |
The nonaqueous electrolyte used in the nonaqueous electrolyte battery of the invention is characterized in that it contains vinylene carbonate (VC) and lithium borofluoride (LiBF<SUB>4</SUB>) and further contains at least one derivative selected from among cycloalkylbenzene derivatives or from among alkylbenzene derivatives having a quaternary carbon atom directly bound to the benzene ring and having no primary or secondary alkyl group directly bound to the benzene ring. The use of such nonaqueous electrolyte makes the storage characteristics of the nonaqueous electrolyte battery at high temperature improve remarkably even when the content of LiBF<SUB>4 </SUB>is reduced, while preventing diminution of battery capacity at the same time. |
