▎ 摘　　要

NOVELTY - The method (100) involves reacting graphene oxide with reductive agent (120) to obtain a first composition. Chemical activation agent is reacted with reduced graphene oxide (130). A portion of particles is removed from the first composition (140) to obtain a second composition. The second composition is heated under reductive atmosphere (150) to obtain a third composition. The third composition, first salt with divalent cation and second salt with trivalent cation are combined (160). The second solution is heated under solvothermal conditions sufficient to obtain a graphene composite (170). USE - Method for making a graphene composite for forming an electrode in a graphene composite capacitor device (claimed). ADVANTAGE - The method enables heating the second solution under solvothermal conditions sufficient so as to obtain the graphene composite for forming the electrode in the graphene composite capacitor device in an efficient manner. DETAILED DESCRIPTION - The particles comprise a polyolefin, polystyrene and acrylic, silica. The salt comprises magnesium ion, zinc ion, copper ion, manganese ion, calcium ion, iron ion, aluminum iodide, chromium ion, Cobalt ion, Gallium ion, Cerium ion and Lanthanum ion.
