Abstract
This application relates to the battery field, and specifically, to a positive electrode plate, an electrochemical apparatus, and an apparatus. The positive electrode plate in this application includes a current collector and an electrode active material layer disposed on at least one surface of the current collector, where the current collector includes a support layer and a conductive layer disposed on at least one surface of the support layer, a single-sided thickness D2 of the conductive layer satisfies 30 nmD23 μm, a thickness D1 of the support layer satisfies 1 μmD130 μm, and the support layer is made of a polymer material or a polymer composite material; and the electrode active material layer includes an electrode active material, a binder, and a conductive agent, and a total thickness Dtotal of the electrode active material layer is not greater than 170 μm.
