NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
PURPOSE:To ensure a high operating voltage and a long cycle life and provide excellent storing characteristic by improving the composition of a positive electrode in a nonaqueous electrolyte secondary battery. CONSTITUTION:A positive electrode 3 is formed from only Li1-XCoO2 (0<X<1) and a binder and laid in the state containing no conductive material such as carbon and metal powders to enhance the capacity. Thus, no oxidation decomposition of an electrolyte is caused, the reduction in conductivity is also less, and a nonaqueous electrolyte secondary battery with a high capacity and a long cycle life can be provided. |
