In this work, we report sub-nanoporous carbon which is synthesized for the first time by means of supramolecular engineering methods for efficient energy storage at the electrode/electrolyte interface. The achieved value of the differential capacitance more than twice exceeds the corresponding value for the known carbon structures. Based on the constructed impedance model and microscopic theory, the physical mechanisms of the investigated processes are suggested.
