Purpose: Mechanism of supramolecular complexes C formation and investigation of their electrochemical characteristics were the aim of this paper. Supramolecular complexes were created by inserting an organic receptor into nano/mesopores of activated carbon. Design/methodology/approach: Electrochemical studies of supramolecular complexes C were carried out by means of impedance spectroscopy, cyclic voltammetry and galvanostatic cycling. Findings: The possibility to combine the capacitive storage with faradaic energy generation in one unit is proved. It can be reached by means of active electrode formation as a supramolecular complex C. It is shown that faradaic generation of energy occurs at low positive potentials, whereas the capacitive one at higher potentials. Method of synthesis of blue graphite is developed. Research limitations/implications: This research is a complete and accomplished work. Practical implications: Supramolecular complexes, obtained in this work, could be regarded as promising electrode materials in devices of energy generation, storage and transformation. Originality/value: This work is of urgent importance for physics and chemistry of energy generation, storage and transformation, because it opens new possibilities to new highly effective electrode materials search and enables to reach a high values of functional characteristics.
