Abstract
Provided are a novel method for manufacturing a stack of carbon nanotube and graphene that can improve a capacitor characteristic, an electrode material including the stack of carbon nanotube and graphene, and an electric double-layer capacitor using the same. A method for manufacturing a stack of graphene and carbon nanotube includes a step of dispersing the graphene in an aqueous MOH solution (M represents an element selected from a group consisting of Li, Na, and K) to adsorb MOH on the graphene, a step of heating the graphene with MOH adsorbed thereon that is obtained in the adsorption step in vacuum or in an inert atmosphere in a temperature range of 400° C. or more and 900° C. or less to form pores in the graphene, and a step of dispersing the carbon nanotube and the graphene with the pores that are obtained in the step of forming the pores in a dispersion medium to stack the carbon nanotube and the graphene with the pores.
