1. A method of making a composite material, the method comprising:
disposing a carbon-based particulate body in an activation solution;
activating surfaces of the carbon-based particulate body while in the activation solution; and
applying a metallic coating to the activated surfaces of the carbon-based particulate body, wherein the carbon-based particulate body includes one or more holes or cavities extending through the carbon-based particulate body, and wherein the carbon-based particulate body includes a plurality of graphene platelet bodies having an irregular shape; and
wherein an interior enveloped by the surface, the surfaces and the interior consisting of carbon-based bodies with metallic coatings fused to one another, wherein the composite material has ampacity that is greater than a dimensionally identical electrical conductor formed from bulk copper.
