NONAQUEOUS ELECTROLYTE BATTERY AND BATTERY PACK |
| 摘要 |
According to one embodiment, a nonaqueous electrolyte battery includes a container, a positive electrode housed in the container, a negative electrode housed in the container, and a nonaqueous electrolyte housed in the container. The positive electrode includes a positive electrode active material represented by a general formula LiMO2 (M is one or more elements selected from a group consisting of Ni, Co, and Mn). The negative electrode is spatially separated from the positive electrode and includes a titanium-containing oxide as a negative electrode active material. A potential of the positive electrode is 3.75 V or more vs. Li/Li+, when an open circuit voltage of a nonaqueous electrolyte battery is 2.17 V. |
