Aspects of the disclosure include copper-graphene (Cu-Gr) multilayer composite (CGMC) current collectors and methods of manufacturing the same. An exemplary vehicle includes an electric motor and a battery pack electrically coupled to the electric motor. The battery pack includes a battery cell with a cell pouch having therein a plurality of stacked anode current collectors alternating with a plurality of stacked cathode current collectors, and an active material dispersed within the cell pouch to cover the current collectors. Each of the anode current collectors is a CGMC current collector including a copper foil substrate having a top surface and a bottom surface. The copper foil substrate is pure copper. A graphene layer is directly on at least one of the top surface and the bottom surface of the copper foil substrate and a plated copper layer is directly on the graphene layer.
