NOVELTY - A manganese oxide/carbon nanotube/graphene anode composite material is produced by: (1) dispersing carbon nanotubes in a permanganate aqueous solution, performing a reflux reaction, naturally cooling, filtering, washing, and drying to obtain a manganese/carbon nanotube precursor; (2) mixing the manganese/carbon nanotube precursor obtained in the step (1) and a polycationic electrolyte aqueous solution, stirring, filtering and drying to obtain a modified manganese/carbon nanotube precursor; (3) dispersing the modified manganese/carbon nanotube precursor obtained in the step (2) in water, then mixing with an aqueous solution of graphene oxide, stirring, filtering and drying to obtain a precursor/graphene mixture; and (4) calcining the precursor/graphene mixture obtained in the step (3) in a protective atmosphere, and cooling to room temperature along with a furnace. USE - Manganese oxide/carbon nanotube/graphene anode composite material. ADVANTAGE - The manganese oxide/carbon nanotube/graphene anode composite material can be simply and industrially produced in an environmentally-friendly manner, and has high electronic conductivity and ionic conductivity, short ion diffusion channel and excellent rate performance.
