NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
Provided is a nonaqueous electrolyte secondary battery having excellent output characteristics. A nonaqueous electrolyte secondary battery 1 includes a positive electrode 12, a negative electrode 11, a nonaqueous electrolyte, and a separator 13. The positive electrode 12 includes a positive electrode current collector, a positive electrode active material layer, and a carbon layer. The carbon layer is provided between the positive electrode current collector and the positive electrode active material layer. The positive electrode active material layer contains a lithium composite oxide. The lithium composite oxide has a molar ratio of nickel to manganese (nickel/manganese) of 6/4 or more. |
