▎ 摘　　要

NOVELTY - The method involves mixing a graphene oxide with deionized water. A reaction kettle is filled with a cobalt product, where reaction temperature of the reaction kettle is120-180 degrees Celsius. A room temperature is obtained with deionized water and ethanol solvent. The cobalt product is coated with a graphite nano-composite material, where dosage ratio of deionized water is 10-30 mg: 5 ml. A cobalt and graphene nano-composite material is formed with a nano-rod stacking structure. USE - Cobalt and graphene nano-composite material manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows XRD pattern of cobalt and graphene nano-composite material.
