Abstract
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.
Claims2
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(OH2).
