Kind Code:
B2
Abstract:
According to one embodiment, there is provided a nonaqueous electrolyte battery (100). The nonaqueous electrolyte battery (100) includes a negative electrode (2), a positive electrode (3), and a nonaqueous electrolyte. The negative electrode (2) includes an oxide of titanium. The positive electrode (3) includes a positive electrode current collector (3a) including aluminum, a positive electrode layer (3b) including a nickel-cobalt-manganese composite oxide including lithium, and a passive film formed on the positive electrode current collector (3a). A ratio p/n of a capacity p of the positive electrode (2) to a capacity n of the negative electrode (3) falls within the range from 1.1 to 1.8.
