A busbar for high conductivity distribution of electrical power within a power module of an electric vehicle (EV). The busbar may include a plurality of multilayer composites having copper-graphene laminations. One or more of the multilayer composite may include a first copper-graphene lamination having a plurality of graphene layers disposed between a plurality of copper layers, a second copper-graphene lamination having a plurality of graphene layers disposed between a plurality of copper layers, and a carrier substrate disposed relative to the first and second copper-graphene laminations.
