  • NEGATIVE CURRENT COLLECTOR, NEGATIVE ELECTRODE PLATE. ELECTROCHEMICAL APPARATUS, BATTERY MODULE, BATTERY PACK, AND DEVICE
    Publication number: 20210119219
    Abstract: This application discloses a negative current collector, a negative electrode plate, an electrochemical apparatus, a battery module, a battery pack, and a device. The negative current collector includes a support layer and a metal conductive layer that is disposed on at least one of two opposite surfaces of the support layer in a thickness direction of the support layer. A density of the support layer is less than a density of the metal conductive layer; and the density of the metal conductive layer is 8.0 g/cm3 to 8.96 g/cm3. A thickness D1 of the metal conductive layer is 300 nm?D1?2 ?m. When a tensile strain of the negative current collector is 2.5%, a sheet resistance growth rate T of the metal conductive layer is T?5%.
