Abstract:
A method for preparing a three-dimensional graphene structure, and an energy storage device are provided, the method including forming a graphene precursor by heating a carbohydrate and a gas generator, forming a graphene structure having a cavity therein by carbonizing the graphene precursor, and forming nanopores in the graphene structure, wherein the nanopores pass through an outer surface and an inner surface of the graphene structure, and are connected with the cavity.
