▎ 摘 要
NOVELTY - The method involves covering polymer layer on a spherical template surface. Graphene oxide solution is coated on the polymer layer of the spherical template surface. Vacuum filtering and drying process and composite filter film peeled off process are performed. Composite film high temperature annealing process is performed to obtain porous structure-shaped thin film. Water heat reaction process is performed in the porous structure-shaped thin film by utilizing potassium permanganate solution to obtain final porous graphene/manganese oxide composite film product. USE - Method for manufacturing porous graphene/manganese oxide composite film of a super capacitor (claimed). ADVANTAGE - The method enables reducing adhesive and electric conduction agent adding requirement, improving machinery property, charging and discharging property, high multiplying power property and operation performance of a super capacitor and prolonging circulation service life of the super capacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a super capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a porous graphene/manganese oxide composite film.
