▎ 摘　　要

NOVELTY - The electrode has a graphene carrier that is provided with a spiral 24 hedral gyroid structure and a manganese dioxide layer is grown on the graphene carrier. The UV curable resin is composed of hexanediol diacrylate and ethoxylated trimethylolpropane triacrylate and a volume fraction is composed of 2% trimethylbenzoyl phosphine oxide diphenyl 2,4,6 trimethylbenzoyl oxyphosphorescent initiator. The silica superstructure template is put into the quartz tube of the tube furnace, and passes argon for 0.5 hours to remove other gases in the quartz tube. The tube furnace is heated at a heating rate of 6 degrees C/min. The ethanol is introduced. The carrier gas of the ethanol is argon, the gas flow is 200sccm, and the reaction is 60min. The graphene sheets are formed on the surface of the template. The hydrofluoric acid solution is drawn out and changed to deionized water to rinse out the remaining solution. USE - Manganese dioxide and graphene superstructure electrode. ADVANTAGE - The spiral tetrahedral structure has a continuous curved surface on which the manganese dioxide layer is deposited uniformly, and has a high specific surface area, and the active material load reaches 20-100mg cm-2. The electrochemical performance is improved. The electrode is kept in working condition under pressure, which solves the poor mechanical performance and low pressure strength of the gel ink printing electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a manganese dioxide and graphene superstructure electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the working condition of the manganese dioxide/graphene superstructure electrode.
