RECHARGEABLE LITHIUM BATTERY |
| 摘要 |
A rechargeable lithium battery includes a separator between a positive electrode and a negative electrode. The positive electrode has a positive electrode coating region and a positive electrode uncoated region. A positive active material is coated to a positive electrode current collector in the positive electrode coating region, and the positive active material is not coated in the positive electrode uncoated region. The negative electrode includes a negative electrode coating region and a negative uncoated region. A negative active material is coated to a negative electrode current collector in the negative electrode coating region, and the negative active material is not coated and a lithium source is in the negative uncoated region. The negative electrode coating region includes an active region corresponding to the positive electrode coating region. The lithium source is at the negative electrode and separated from an end of the active region by a predetermined interval. |
