ELECTRODE PLATE, ELECTROCHEMICAL APPARATUS, AND APPARATUS

This application relates to the battery field, and specifically, to an electrode plate, an electrochemical apparatus, and an apparatus. This application relates to an electrode plate, including a current collector and an electrode active material layer disposed on at least one surface of the current collector. The current collector includes a support layer and a conductive layer disposed on at least one surface of the support layer, where single-sided thickness D2 of the conductive layer satisfies: 30 nm ≤ D2 ≤ 3 µm, the support layer includes a polymer material or a polymer composite material, and thickness D1 of the support layer satisfies: 1 µm ≤ D1 ≤ 20 µm.The electrode active material layer includes an electrode active material, a binder, and a conductive agent, where total thickness Dtotal of the electrode active material layer satisfies: 200 ≥ Dtotal/D1≥ 1, and based on total weight of the electrode active material layer, the binder content in the electrode active material layer is not less than 1wt%. The electrode plate in this application has good workability, and the electrochemical apparatus and the apparatus including the electrode plate have high energy density, good electrical performance, and good safety.
