摘要

PROBLEM TO BE SOLVED: To provide a method for producing a laminate of graphene and carbon nanotubes for improving capacitor characteristics, an electrode material comprising a laminate of graphene and carbon nanotubes, and an electric double layer capacitor using the same. SOLUTION: A method of manufacturing a laminate of graphene and carbon nanotubes includes dispersing graphene in an MOH aqueous solution (M is an element selected from the group consisting of Li, Na, and K), and adsorbing MOH to graphene. Heating the graphene adsorbed with MOH in a vacuum or in an inert atmosphere at a temperature range of 400 ° C. to 900 ° C. to form pores in the graphene; and graphene and carbon having pores A step of dispersing nanotubes in a dispersion medium and laminating graphene having pores and carbon nanotubes.
