Abstract
According to one embodiment, provided is a nonaqueous electrolyte battery including a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes a spinel type lithium-manganese composite oxide and a lithium cobalt oxide, which satisfy formula (1): 0.01≤B/(A+B)<0.05. The negative electrode includes a titanium-containing oxide. The nonaqueous electrolyte battery satisfies formula (2): 0.3≤C/D 0.8. A is a weight ratio (wt %) of the spinel type lithium-manganese composite oxide. B is a weight ratio (wt %) of the lithium cobalt oxide. C is a pore specific surface area (m/g) of the positive electrode. D is a pore specific surface area (m/g) of the negative electrode.
