ELECTRODE PLATE, ELECTROCHEMICAL APPARATUS, BATTERY MODULE, BATTERY PACK, AND DEVICE

This application relates to an electrode plate, an electrochemical apparatus, a battery module, a battery pack, and a device. The electrode plate includes 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, a single-sided thickness D of the conductive layer satisfies: 30 nm≤D≤3 μm; and a conductive primer layer containing a conductive material and a binder is disposed between the current collector and the electrode active material layer, the binder in the conductive primer layer containing an acrylic based/acrylate based water-dispersible binder. The electrode plate of this application has good quality, and the electrochemical apparatus containing the electrode plate has a high energy density and a good electrical performance and long-term reliability.
