Abstract: A battery and an electrical device are provided. The battery includes at least one first battery cell and at least one second battery cell, an internal resistance of the first battery cell is greater than that of the second battery cell, and a heat transfer rate of the first battery cell is less than that of the second battery cell.

Abstract: The present application relates to a current collector, an electrode plate, a battery cell, a battery, and an electric device. The current collector includes a stainless steel current-collecting portion for collecting a current, where the stainless steel current-collecting portion includes a blank area and a coating area that are arranged adjacent to each other in a preset direction, the coating area is configured to be coated with an active material, and the blank area has a hardness less than that of the coating area.

Abstract: A network scan may be performed, and the best network may be selected in real time in the device after evaluating all available carriers whose network information is gathered by network scanning The network scan enables the device to fairly compare the connectivity of the available carrier services and can be used to improve the on-device network selection. The network scan may be further used in order to ensure the existence of a better carrier service before switching. Accordingly, this may reduce unnecessary poor switches to networks having lower quality connections and increase good switches to networks having better quality. The present disclosure provides for determining when to run network scan and how to use the scan results to make the cell network selection decision.
