Abstract: The present disclosure relates to a power supply assembly and a method for manufacturing the same. The power supply assembly includes a negative electrode sheet, a separator, and a positive electrode sheet. The negative electrode sheet includes a negative tab, and the positive electrode sheet includes a positive tab, a positive electrode material covering a first foil, a first recess and a second recess. The first recess is formed by removing a positive electrode material covering a first region of the first foil and configured for receiving the positive tab, and a size of the first recess is larger than a size of the positive tab. The second recess is formed by removing a positive electrode material covering a second region of the first foil and configured for receiving the negative tab, and a size of the second recess is larger than a size of the negative tab.

Abstract: A charging control method, and an electronic device and/or a storage medium implementing the charging control method, includes: determining a current state parameter of a battery, wherein the battery is charged with a first charging parameter corresponding to a first charging stage defined in a staged charging strategy; determining an expected state parameter of the battery after continuing to be charged for a preset time period based on the current state parameter and the first charging parameter; and charging the battery with a second charging parameter corresponding to a second charging stage defined in the staged charging strategy, when the expected state parameter matches the second charging stage.
