Abstract
According to one embodiment, there is provided a nonaqueous electrolyte battery. The nonaqueous electrolyte battery includes a negative electrode, a positive electrode, and a nonaqueous electrolyte. The negative electrode includes an oxide of titanium. The positive electrode includes a positive electrode current collector including aluminum, a positive electrode layer including a nickel-cobalt-manganese composite oxide including lithium, and a passive film formed on the positive electrode current collector. A ratio p/n of a capacity p of the positive electrode to a capacity n of the negative electrode falls within the range from 1.1 to 1.8.
