▎ 摘  要

NOVELTY - The porous anode material structure comprises an integral three-dimensional (3D) graphene-carbon hybrid foam including multiple pores with a pore volume, and pore walls. An anode active material is coated with a coating volume on surfaces of the pore walls. The pore walls contain single-layer or multi-layer graphene sheets chemically bonded by a carbon material. The multi-layer graphene sheets have 2-10 layers of stacked graphene planes with an inter-plane spacing. The non-pristine graphene is selected from graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination. USE - Porous anode material structure for a lithium-ion battery for use in the battery anode of a battery(all claimed). ADVANTAGE - Porous anode material structure provides a graphene/carbon foam-protected anode active material coating and a cost-effective process for producing highly conductive, mechanically robust graphene-based foams that can support and protect an anode active material coating bonded to pore walls in the foam. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the 3D graphene-carbon hybrid foam.
