Abstract
An electrode plate includes a current collector and an electrode tab. The current collector includes a support layer and a conductive layer. The conductive layer is located at least on a surface of a side of the support layer, and the electrode tab includes a main body portion and a connecting portion adjoining the main body portion, the connecting portion is connected to the conductive layer, and the main body portion extends in a direction away from the current collector. In an MD of the electrode plate, a length of the connecting portion of the electrode tab is greater than a length of the main body portion of the electrode tab.
