  "textContent": "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. And the electrode active materials include small particle active materials with an average particle size D50 of 1.0 µm to 7.0 µm and large particle active materials with an average particle size D50 of 7.1 µm to 20.0 µm. The electrochemical apparatus including the positive electrode plate has high energy density, good safety performance (especially nail penetration safety performance), and good electrochemical performance.",
