| 简介 |
A nonaqueous electrolyte secondary battery is prevented from decreasing the remaining capacity and returned capacity at the time of continuous charge at high voltages and high temperatures. The battery has positive and negative electrodes, and a nonaqueous electrolytic solution containing ethylene carbonate and fluoroethylene carbonate as a solvent. The positive electrode contains a positive-electrode active material with the fine particles of a rare earth element compound deposited on its surface in a dispersed state. |
