1. A method of making a composite wire material, the method comprising:
annealing a core wire comprising at least 99.0% copper (Cu) at a temperature of about 850° C. to about 1100° C. under flowing mixed gaseous conditions comprising argon (Ar) and hydrogen (H2);
coating graphene on a circumferential surface of the core wire to generate a graphene layer; and
coating nickel (Ni) on the circumferential surface of the graphene layer to generate a nickel (Ni) layer.
