New trends in nanoscale compounds for energy storage

Purpose: Mechanism of supramolecular complexes C formation and investigation of theirelectrochemical characteristics were the aim of this paper. Supramolecular complexes were created by insertingan organic receptor into nano/mesopores of activated carbon.Design/methodology/approach: Electrochemical studies of supramolecular complexes C werecarried 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 isproved. 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 athigher 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 promisingelectrode materials in devices of energy generation, storage and transformation.Originality/value: This work is of urgent importance for physics and chemistry of energy generation, storageand transformation, because it opens new possibilities to new highly effective electrode materials search andenables to reach a high values of functional characteristics.
