▎ 摘　　要

NOVELTY - The method involves applying the graphene oxide on a capacitor electrode material and a cobalt precursor. The mixture mixing the iron precursor and the solvent is prepared. The prepared mixture is annealed. The iron precursor consisting of the graphene and the cobalt iron oxide is mixed in mole ratio of the iron. USE - Manufacturing method of composite containing crumpled graphene and cobalt-iron oxide. ADVANTAGE - The thermal process is made simple and the series processing is made possible. The electrical characteristic is improved and the surface area of the graphene structure is increased. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a composite; and (2) a super capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of manufacturing method of composite containing crumpled graphene and cobalt-iron oxide. (Drawing includes non-English language text)
