The most common application of highly ordered nanoporous carbon materials is electric double-layer capacitors (EDLCs): EDLCs are extensively used in electric vehicles and other industrial fields. There are two important prerequisites for achieving efficient EDLCs. First, a high surface area of carbon materials is required to achieve EDLCs with high energy density, as Sg and Sv are directly related to the gravimetric and volumetric capacities, respectively. This can be realized by high porosity and small pore size because EDLCs can be charged in principle through the physisorption of electrolyte ions onto the nanopore surfaces of a carbon electrode. Importantly, this often causes a lower efficiency of mass transportation within nanostructured materials because the ions have to be transferred from the outside into the porous architecture of the electrode materials before physisorption in the EDLC process can occur. 3D structural regularity helps overcome these issues. For example, despite their microporous structure, ZTCs facilitate the efficient conveyance of ions under electrochemical conditions owing to their highly ordered architecture. This results in a high gravimetric capacitance of 140-190 F g -1 even at a high current of up to 20 A g -1 . Ideal 3D graphene materials with such structural regularity and a continuous graphene architecture will realize highly efficient EDLCs in terms of energy efficiency and stability.
