description An electrode plate includes a current collector. The current collector includes a conductive layer and an insulating layer. The conductive layer includes a tab portion. In thickness direction of the electrode plate, the conductive layer is provided at two opposite sides of the insulating layer. The insulating layer includes a first region and a second region, and in width direction of the electrode plate, at least one end of the first region is connected to the second region. Thickness of the second region is less than thickness of the first region, and the tab portion is at least partially disposed in the second region. The electrode plate further includes an active substance layer applied on a surface of the conductive layer facing away from the insulating layer. The tab portion is not coated with the active substance layer.
