Abstract
A non-aqueous electrolyte battery of the present invention includes a non-aqueous electrolyte containing a lithium salt, a cyclic sultone derivative, and an acid anhydride, wherein the non-aqueous electrolyte contains the cyclic sultone derivative in an amount of 0.3 to 3% by mass and the non-aqueous electrolyte contains the acid anhydride in an amount of 0.3 to 3% by mass. Furthermore, the non-aqueous electrolyte battery includes at least one selected from a cyclic sultone derivative and an acid anhydride, and an electrolyte salt. The electrolyte salt contains lithium salt A and lithium salt B. The lithium salt A is at least one selected from LiBF, LiPF, LiAsF, and LiSbF, and the lithium salt B is a lithium salt other than the lithium salt A. The electrolyte contains the lithium salt A in an amount of 2 mol % or more.
