Skin effect enhanced high conductive composite stator winding bundles in e-motors

A method of forming composite wire bundles for a stator, comprising:

• oxidizing copper included in a first surface of a copper-graphene multilayer composite formed on each of a plurality of copper wires;
• applying a fluoropolymer on the first surface of the copper-graphene multilayer composite formed on each of the plurality of copper wires, wherein the copper included in the first surface of the copper-graphene multilayer composite is oxidized before applying the fluoropolymer;
• curing the fluoropolymer;
• consolidating the plurality of copper wires;
• forming a fluoropolymer matrix with the applied fluoropolymer, wherein the fluoropolymer matrix surrounds the first surfaces;
• and
• forming a jacket around the fluoropolymer matrix.
