Abstract: This application discloses an electrode plate, an electrode assembly, a battery cell, a battery, and an electrical device. The electrode plate includes: a current collector, where the current collector includes a base film layer and metal layers, and the metal layers are disposed on the base film layer in a spaced-apart manner; and active material layers, where the active material layers are applied to the base film layer in a spaced-apart manner. Each active material layer at least partially covers a corresponding metal layer.
