Abstract
The electrode plate includes a current collector and an electrode active material layer disposed on at least one surface of the current collector, wherein the current collector includes a support layer and a conductive layer, the conductive layer has a single-sided thickness Dsatisfying: 30 nm≤D≤3 μm; the electrode active material layer is divided into two regions, an inner region and an outer region in a thickness direction of the electrode active material layer, in which the weight percentage of the conductive agent in the inner region of the electrode active material layer is higher than the weight percentage content of the conductive agent in the outer region of the electrode active material layer, and the conductive agent in the inner region of the electrode active material layer includes at least one of a one-dimensional conductive material and a two-dimensional conductive material.
