ELECTRODE PLATE, ELECTROCHEMICAL APPARATUS, AND 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-side 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 Dof the electrode active material layer satisfies: 200≥D/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 1 wt %.
