USE - Three-dimensionally ordered macroporous structure type graphene-like carbon material for use as electrode material or electro-catalyst (claimed) in lithium-ion battery. ADVANTAGE - The graphene-based material prepared by the method has a Three-dimensionally ordered macroporous structure, high porosity, high specific surface area, extensive structural defects and high conductivity. The lithium-ion battery has excellent energy storage performance and electro-catalytic performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) three-dimensionally ordered macroporous structure type graphene/metal or metal oxide hybrid material which comprises three-dimensional ordered macroporous structure, and has primary pore diameter of 200-300 nm and secondary pore diameter of 100-150 nm. The pore walls are composed of nitrogen-doped graphene-like carbon and metal crystals or metal oxides. The thickness of the pore wall is 30-50 nm; (2) method of producing graphene/metal or metal oxide hybrid material with three-dimensionally ordered macroporous structure, which involves (i) weighing the orderly array of poly(methyl methacrylate) microspheres to form a hard template impregnated in a metal nitrate solution, drying by suction filtration at room temperature to obtain precursor, (ii) placing the resulting precursor in a tubular furnace, and calcining in an inert atmosphere to obtain a corresponding three-dimensionally ordered macroporous structure of graphene/metal or metal oxide hybrid material; and (3) method for three-dimensionally ordered macroporous structure type graphene charcoal material, which involves removing metal crystal or metal oxide in the three-dimensionally ordered macroporous structure-graphene/metal or metal oxide hybrid material by chemical etching, or by high-temperature evaporation method to remove metal components, where chemical etching uses corrosive solution to corrode metal crystals or metal oxide.
