Abstract: Sheet-shaped mixture layers are placed on both sides of a current collector to form an electrode (positive electrode) with a layered structure. The electrode with a layered structure and a counter electrode (negative electrode) thereof are wound via a separator, while a positional shift in a winding direction is caused between the current collector and the sheet-shaped mixture layers of the electrode with the layered structure, whereby a winding body is formed. The winding body is placed in a battery case (outer can) to constitute a battery. Particularly, in the electrode with a layered structure, by forming the current collector of a plain-woven wire net, a metal foil, expanded metal, a lath, or punching metal, a battery with satisfactory productivity suitable for an intermediate load can be provided at a low cost.

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 LiBF4, LiPF6, LiAsF6, and LiSbF6, 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.
