NOVELTY - Modified graphite carbon material comprises a graphite carbon material, a dispersant, an aqueous solution and an organic carbon source liquid. The preparation of carbon material comprises (i) heating graphite, water-soluble solution, coating agent, dispersant, and organic carbon source solution, and stirring to obtain slurry; (ii) introducing graphite carbon material into a high-speed mixer for crushing, and mixing graphite and carbon material at 120-180 revolutions/minute, adding dispersant and coating agent for mixing, and drying to obtain mixture A; (iii) mixing mixture A with aqueous solution and organic carbon source solution, and stirring at 10-20 revolutions/minute to obtain mixture B; (iv) placing mixture B into a dryer for concentration and drying to obtain a gel phase, and air-cooling gel phase to room temperature; (v) sintering carbonizing dried gel phase to obtain graphite carbon material powder; (vi) crushing graphitic carbon material, and ball milling. USE - Used as modified graphite carbon material. ADVANTAGE - The carbon material is easy to realize industrial production, and has uniform particle size and good dispersibility.
