NOVELTY - The preparation of conductive composite graphene involves (1) dissolving metal halide electrolyte salt in solvent to obtain electrolyte solution, (2) placing graphite material into electrolyte solution, leaving stand, inter-penetrating metal ions of electrolyte solution into graphite material layer to form intercalated graphite, (3) placing intercalated graphite at 700-900 degrees C, reacting metal halide salt with solvent, decomposing to obtain metal oxides and gases, cooling to obtain metal oxide intercalated graphite, (4) heating intercalated graphite, reducing metal oxide, and cooling. USE - Preparation of mechanical peeling type highly conductive composite graphene (claimed). ADVANTAGE - The method enables preparation of mechanical peeling type highly conductive composite graphene with uniform metal particles distribution, safety, reliability, reduced cost, and is environmentally-friendly and suitable for large scale production, and avoids the use of highly active alkali metal. DETAILED DESCRIPTION - The preparation of conductive composite graphene involves (1) dissolving metal halide electrolyte salt in solvent to obtain electrolyte solution, where solvent is aqueous solution of organic acid or organic acid salt, (2) placing 10-200 mg/l graphite material into electrolyte solution, leaving stand for 1-5 days, inter-penetrating metal ions of electrolyte solution into graphite material layer to form intercalated graphite, (3) placing intercalated graphite at 700-900 degrees C for 0.5-1 hour under protective gas conditions, reacting metal halide salt with solvent, decomposing to obtain metal oxides and gases, increasing the distance between the graphite layers, cooling to obtain metal oxide intercalated graphite, (4) heating metal oxide intercalated graphite under protective gas conditions at 900-1500 degrees C for 0.5-1 hour, reducing metal oxide, and cooling to obtain metal intercalated graphite.
