Abstract
Embodiments of the present technology include graphene-metal composites. An example graphene-metal composite comprises a porous metal foam substrate, a graphene layer deposited to the porous metal foam substrate, a metal layer applied to the graphene layer, and another graphene layer deposited to the metal layer; the multilayered porous metal foam substrate being compressed to form a graphene-metal composite.

A method for manufacturing a graphene-metal composite comprising:
- depositing graphene onto a porous metal foam substrate;
- growing carbon nanotube ropes throughout the porous metal foam substrate using a catalyst material and a heated carbon-rich gas flowing over the porous metal foam substrate, wherein the carbon nanotube ropes occupy voids within the porous metal foam substrate;
- and
- compressing the porous metal foam substrate with graphene applied to form a graphene-metal composite, when compressed the carbon nanotube ropes leaving a thermal and electrical pathway through the porous metal foam substrate.
