Abstract
Official abstract text for this publication.
The present invention relates to a three-dimensional graphene composite, a preparation method for the same, and a supercapacitor including the same, and more particularly to a three-dimensional graphene composite including at least one electrode material nanoparticle selected from a transition metal hydroxide, a transition metal oxide and a conducting polymer as adsorbed onto the surface of a three-dimensional graphene foam, a preparation method for the three-dimensional graphene composite, and a supercapacitor including the three-dimensional graphene composite.
First claim
Opening claim text (preview).
What is claimed is: 1. A three-dimensional graphene composite comprising: a graphene foam having a three-dimensional structure with a plurality of pores; and an electrode material nanoparticle adsorbed onto the graphene foam, wherein the electrode material nanoparticle is a transition metal hydroxide, wherein the transition metal hydroxide is at least one selected from the group consisting of copper hydroxide (Cu(OH) 2 ) and manganese-aluminum hydroxide (Mn—Al(OH 2 ). 2. A supercapacitor having an electrode using the three-dimensional graphene composite as claimed in claim 1 .
