| 发明名称 | Nonaqueous electrolyte secondary battery and method for manufacturing the same | ||
| 摘要 | According to one embodiment, there is provided a nonaqueous electrolyte secondary battery including a positive electrode, a negative electrode containing a titanium-containing oxide, and a nonaqueous electrolyte. The nonaqueous electrolyte contains carbon monoxide and at least one selected from difluorophosphoric acid and monofluorophosphoric acid. The ratio of the mass concentration of carbon monoxide to the sum of the mass concentrations of difluorophosphoric acid and monofluorophosphoric acid is in the range of 0.1 to 5%. | ||
