Battery cell, manufacturing method thereof, battery and electronic device |
| abstract |
The application discloses a battery cell, a manufacturing method of the battery cell, a battery and an electronic device. The battery cell manufacturing method comprises the following steps: providing a positive electrode substrate; forming a first positive electrode active material layer by disposing a positive electrode active material on the surface of the positive electrode sheet substrate; and performing deactivation treatment on the edge region of the first positive electrode active material layer to form a second positive electrode active material layer, wherein the second positive electrode active material layer has a conductivity of not more than 10 < -10 > S/m. The second active material layer with the conductivity not greater than 10^ (-10) S/m is arranged in the edge area of the positive plate of the battery cell, so that the phenomenon of lithium metal deposition on the negative plate of the cell can be reduced, and the service life of the cell is further prolonged. |
