  "textContent": "This application relates to the battery field, and specifically, to an electrode plate, an electrochemical device, and an apparatus. The electrode plate of 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, the support layer is made of a polymer material or a polymer composite material, and a thickness D1 of the support layer satisfies 1 µm ≤ D1 ≤ 30 µm; and the electrode active material layer includes an electrode active material, a binder, and a conductive agent, when viewed in a width direction of a coated surface of the electrode plate, the coated electrode active material layer includes three zones classified by compacted density, and compacted density of a middle zone is greater than compacted density of zones on both sides. The electrode plate, the electrochemical device, and the apparatus in this application have high energy density, and good electrical performance and safety.",
