NOVELTY - A thin graphene composite material is prepared by taking graphite materials as raw material, milling using milling equipment with superacid as milling aid, adding nanomaterial, milling for 48 hours, filtering graphene-containing mixture to obtain filter cake, washing, and drying. USE - Method for preparing thin graphene composite material (claimed) used for manufacturing lithium battery, electric conduction rubber, electric conduction coating, printing ink, and super capacitor electrode. ADVANTAGE - The method is short, simple, and low-cost.
