▎ 摘　　要

NOVELTY - The structure provided with a structure electrode and a cement-based electrolyte (6) arranged on both sides of the structure electrode. The structure electrode is composed of a reducing oxidation graphene (3) and foam nickel (2). The cement electrolyte is made of solid waste, cement, water and water reducing agent. The reduction oxidation graphene is coated on the surface of the foam nickel. The reduction oxidation graphene is directly contact with a cement-based electrolyte. The solid waste provided with steel slag powder and glass powder. USE - Graphene capacitor coated with foam nickel/cement structure. ADVANTAGE - The reduction oxidation graphene foam nickel structure electrode has excellent conductivity, solid waste cost of the modified cement-based electrolyte is low, the comprehensive utilization of the resource and the harmless and resource treatment of the industrial waste are realized. The structure super capacitor not only keeps excellent mechanical property and high capacitance, but also is suitable for large-scale application in the building field, it is hopeful to realize structure-function integration of green building energy storage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene capacitor coated with foam nickel/cement structure preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a graphene capacitor coated with foam nickel/cement structure.
