Abstract
This application relates to the battery field, and specifically, to an electrode plate, an electrochemical apparatus, a battery module, a battery pack, and a device. The 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-side thickness Dof the conductive layer satisfies 30 nm≤D≤3 μm, and a conductive primer layer including a conductive material and a bonding agent is further disposed between the current collector and the electrode active material layer. The electrode plate in this application has good machinability. An electrochemical apparatus including the electrode plate has high energy density, good electrical performance, and long-term reliability.
