Beschreibung
Zusammenfassung:	An electrolyte for a non-aqueous electrolyte battery according to the present invention contains a non-aqueous organic solvent; a solute; and both of difluorobis(oxalato)phosphate and tetrafluoro(oxalate)phosphate as additives. A non-aqueous electrolyte battery according to the present invention uses the above electrolyte. By the composite effect of the difluorobis(oxalato)phosphate and tetrafluoro(oxalate)phosphate in the non-aqueous electrolyte and the non-aqueous electrolyte battery, it is possible to improve not only the cycle characteristics and high-temperature storage stability of the battery but also the low-temperature characteristics of the battery at temperatures of 0°C or lower.
