NOVELTY - Super capacitor preparation involves mixing three-dimensional porous graphene composite material, acetylene black and 15% polytetrafluoroethylene emulsion in a weight ratio of 76-84:12-18:5-8 to form a mixture. The formed mixture is ground to form dubbed electrode paste, which is uniformly dispersed in absolute ethanol, and then uniformly coated on surface of nickel foam to form a sheet. The formed sheet is dried in vacuum to form an electrode sheet. USE - Method for preparing super capacitor (claimed). DETAILED DESCRIPTION - Super capacitor preparation involves mixing three-dimensional porous graphene composite material, acetylene black and 15% polytetrafluoroethylene emulsion in a weight ratio of 76-84:12-18:5-8 to form a mixture. The formed mixture is ground to form dubbed electrode paste, which is uniformly dispersed in absolute ethanol, and then uniformly coated on surface of nickel foam to form a sheet. The formed sheet is dried in vacuum to form an electrode sheet. The formed electrode sheet and polypropylene porous membrane are immersed in an electrolyte solution, and then placed in button battery housing package to form super capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation depicting different electric current density. (Drawing includes non-English language text).
