NEGATIVE CURRENT COLLECTOR, NEGATIVE ELECTRODE PLATE, ELECTROCHEMICAL APPARATUS, BATTERY MODULE, BATTERY PACK, AND DEVICE

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 8.0g/cm to 8.96g/cm. A thickness D of the metal conductive layer is 300nm≤D≤2µm. 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%. The negative current collector provided in this application can have both a small weight and good conductivity and current collection performance, and therefore the electrochemical apparatus has both a higher weight energy density and good electrochemical performance.
