  "textContent": "This application discloses a positive current collector, a positive electrode plate, an electrochemical apparatus, a battery module, a battery pack, and a device. The positive current collector includes a support layer, having two opposite surfaces in a thickness direction of the support layer; and an aluminum-based conductive layer, disposed on at least one of the two surfaces of the support layer. A thickness Dof the aluminum-based conductive layer is 300 nm≤D≤2 μm; a density of the aluminum-based conductive layer is 2.5 g/cmto 2.8 g/cm; and when a tensile strain of the positive current collector is 2.5%, a sheet resistance growth rate T of the aluminum-based conductive layer is T≤10%. The positive current collector provided in this application has a relatively small weight and higher electrical performance, so that the electrochemical apparatus provides a higher weight energy density and higher electrochemical performance.",
