Abstract: A non-aqueous electrolyte battery with improved cyclic characteristics and battery capacity at high temperature and capable of suppressing the evolution of gas during storage at high temperature while maintaining favorable cyclic performance, wherein vinylene carbonate (VC) and ?-angelica lactone (4-hydroxy-3-pentenic acid ?-lactone) are contained in the electrolyte, and whereby a highly soft and flexible coating film with ?-angelica lactone is formed on the surface of the negative electrode without reducing the initial charging efficiency of the battery. Since a mixed coating film comprising VC and ?-angelica lactone is formed on the soft and flexible coating film and the mixed coating film has higher thermal stability at high temperature than that of the coating film formed only with VC, the cyclic characteristics of the battery at high temperature can be improved while enhancing the suppression of gas evolution during storage at high temperature.
