Methods of Joining Multilayer Copper-Graphene Coated Current Collectors to Battery Cans and Between Windings in Electric Motor Stators

A method of forming an electrical connection in for a vehicle, comprising:

• joining a first electrical component including a first joining area to a conductor including a second joining area, wherein the conductor includes a substrate including a first surface, and a copper-graphene multilayer composite formed on the first surface;
• and
• forming a fusion zone between the first electrical component in the first joining area and the conductor in the second joining area,
• wherein the copper-graphene multilayer composite includes at least one of the following composite structures:
• a) alternating layers of graphene and copper deposited on the substrate, b) graphene particles dispersed in a copper matrix, and c) alternating layers of graphene and copper deposited on a copper foil, wherein the copper foil is wrapped around the substrate.

A method of joining an electrical component for a vehicle, comprising:

• applying a layer of adhesive to a first joining area of a first electrical component;
