Abstract: An electrode plate includes a current collector and an active substance layer disposed on a surface of at least one side of the current collector. The active substance layer has a first active substance region and a second active substance region. A sectional area of the second active substance region in a preset section is smaller than a sectional area of the active substance layer in the preset section. The preset section is parallel to a preset surface and passes through the second active substance region. The preset surface is a surface of the current collector at which the active substance layer is located. A porosity of the first active substance region is smaller than a porosity of the second active substance region. Pores in the first active substance region and in the second active substance region all have a pore size smaller than or equal to 1 μm.
