Original Abstract Submitted
A current collector includes a support layer and a first conductive layer and a second conductive layer that are disposed on two sides of the support layer in a thickness direction of the current collector. The current collector is divided into a first blank foil section and a coated section disposed in sequence in a second direction. A first active material layer is located on the coated section and disposed on a surface of the first conductive layer, the surface being oriented away from the support layer. A second active material layer is located on the coated section and disposed on a surface of the second conductive layer, the surface being oriented away from the support layer. Along the thickness direction of the current collector, a part of a projection of the first active material layer does not coincide with a projection of the second active material layer.
