THREE-DIMENSIONAL GRAPHENE COMPLEX, MANUFACTURE MATHOD THEREOF, AND SUPER CAPACITY USING THE SAME

摘要

The present invention relates to a three-dimensional graphene complex, to a manufacturing method thereof and to an ultra-high-capacity capacitor including the same. More particularly, the present invention relates to a three-dimensional graphene complex having transition metal hydroxide, and more specifically, nickel-cobalt transition metal hydroxide with nickel and cobalt combined in an optimal stoichiometric ratio, impregnated on three-dimensional graphene foam and adsorbed to the surface; to a manufacturing method thereof; and to an ultra-high-capacity capacitor (super-capacitor) including the same. According to the present invention, nanostructures can be grown effectively via chemical bath deposition, which is relatively simple and economical, based on current collectors having light weight and high conductivity owing to a foamed resin structure with a thin graphene skeleton to be applied usefully for an ultra-high-capacity capacitor electrode with high energy density or the like, which has capacitance increased significantly.
