According to one embodiment, a nonaqueous electrolyte battery (10) includes a container (2), a positive electrode (5) housed in the container (2), a negative electrode (3) housed in the container (2), and a nonaqueous electrolyte housed in the container (2). The positive electrode (5) includes a positive electrode active material represented by a general formula LiMO 2 (M is one or more elements selected from a group consisting of Ni, Co, and Mn). The negative electrode (3) is spatially separated from the positive electrode (5) and includes a titanium-containing oxide as a negative electrode active material. A potential of the positive electrode (5) is 3.75 V or more vs. Li/Li + , when an open circuit voltage of a nonaqueous electrolyte battery (10) is 2.17 V. |
