Claim:
1. A method of producing an integral 3D graphene-carbon hybrid foam directly from a graphitic material, said method comprising: (a) mixing multiple particles of a graphitic material and multiple particles of a solid polymer carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; (b) operating said energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from said graphitic material and transferring said graphene sheets to surfaces of said solid polymer carrier material particles to produce graphene-coated or graphene-embedded polymer particles inside said impacting chamber; (c) recovering said graphene-coated or graphene-embedded polymer particles from said impacting chamber and consolidating said graphene-coated or graphene-embedded polymer particles into a desired shape of graphene-polymer composite structure; and (d) pyrolyzing said shape of graphene-polymer composite structure to thermally convert said polymer into pores and carbon or graphite that bonds said graphene sheets to form said integral 3D graphene-carbon hybrid foam.
