NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
A non-aqueous electrolyte secondary battery having a high capacity and a long life is provided by eliminating or reducing the structural change of a positive electrode active material at high voltages. The non-aqueous electrolyte secondary battery includes a positive electrode having a positive electrode active material that intercalates and deintercalates lithium ions, a negative electrode having a negative electrode active material that intercalates and deintercalates lithium ions, and a non-aqueous electrolyte. The positive electrode active material includes a lithium-cobalt composite oxide containing nickel, manganese, aluminum, and germanium. The percentage of cobalt in the lithium-cobalt composite oxide is 80 mol % or more with respect the total molar amount of metal elements except lithium. |
