发明名称 非水電解液電池用電解液及び非水電解液電池
摘要 Disclosed is an electrolyte for nonaqueous electrolyte cells, which contains a nonaqueous organic solvent and a solute. This electrolyte is characterized by containing as additives at least one compound selected from a first compound group consisting of bis(oxalato)borate, difluoro(oxalato)borate, tris(oxalato)phosphate, difluoro(bisoxalato)phosphate, and tetrafluoro(oxalato)phosphate, and at least one compound selected from a second compound group consisting of a sulfonate group-containing imide salt, which is represented by the general formula M[R 1 OSO 2 NSO 2 OR 2 ] n , and a phosphoryl group-containing imide salt, which is represented by the general formula M[R 3 R 4 OPNPOR 5 R 6 ] m . This electrolyte provides nonaqueous electrolyte cells with high-temperature durability without causing swelling and performance deterioration of batteries.
