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 nm≤D2≤3 μm. A thickness D1 of the support layer satisfies 1 μm≤D1≤30 μm. The support layer is made of a polymer material or a polymer composite material. The electrode active material layer includes electrode active materials, a binder, and a conductive agent.
