The carbonaceous nanocomposite according to the present disclosure has excellent adhesivity to the substrate and can be attached to the substrate without undergoing a pasting process. Since a two-directional current flow is generated, the electrical resistance of the graphene and carbon nanotube is considerably reduced. In addition, the graphene allows the carbon nanotube to have a high current density and a high specific surface area, thereby accelerating a redox reaction. The excellent heat-radiating property of the graphene sheet allows fast transfer of heat generated in the carbon nanotube to outside, thereby avoiding degradation of the carbon nanotube. Thus, when employed as an electrode for a battery or a field emission display, a higher current density and an extended lifespan can be achieved when compared with the existing art.08-02-2012
