EDLC electrodes which exhibit both high power and high energy densities have been developed. The target structure was "ordered mesoporous carbons composed of single graphene walls". First, it has been successfully demonstrated that the target structure offers a fast ion-transfer, thereby realizing a high power density. Moreover, we attempted to decrease the pore size as small as possible with keeping a high power performance to increase a volumetric energy density. As the result, it was found that even 1.2-nm micropores exhibit a high power performance if they are three-dimensionally arrayed and mutually connected.
