Abstract:
1. A nonaqueous electrolyte battery comprising a positive electrode comprising a positive electrode current collector and a positive electrode layer provided on the positive electrode current collector; a negative electrode comprising a negative electrode current collector and a negative electrode layer provided on the negative electrode current collector; and a nonaqueous electrolyte, wherein the positive electrode layer contains a positive electrode active material, the positive electrode active material containing a lithium-nickel-cobalt-manganese complex oxide represented by the formula Li the negative electrode layer contains a negative electrode active material, the negative electrode active material containing at least one selected from a lithium titanate having a spinel structure and a monoclinic β-type titanium complex oxide, and at least one selected from a oxide which has a spinel structure and represented by the formula AFe a ratio of the total mass of the oxide represented by the formula AFe a capacity of the negative electrode is larger than that of the positive electrode.
