Venhryn B. The influence mechanisms of fractal structure and impurity energetic topology of nonporous bio carbons on the effectiveness of energy accumulation at their boundary with electrolyte

The results of research of influence of a fractal structure and impurity energy topology of nanoporous carbons on efficiency of accumulation of energy at their boundary with an electrolyte are presented in dissertation. Intercalation and ultrasonic activation modifications were used to change the fractal structure and impurity energy topology of nanoporous carbons. It was found that the effect of ultrasonic irradiation on the processes of polarization of the bulk charge of a double electric layer formed at the nanoporous carbon and electrolyte interface can be considered as direct redistribution of impurities and intrinsic defects, and as a consequence in the modification of the impurity energy topology and in the effect on percolation mobility through ultrasonic modification of the fractal structure. It was found that the influence of ultrasonic irradiation on the pseudo-capacitive energy accumulation depends on the process conditions: cavitation or precavitation. The inclusion of 3d or 4f metals into carbon materials causes a drastic increase of the free carriers concentration, which due to the reduction of the Thomas-Fermi screening radius, causes the growth of specific capacitance and the decrease of series resistance. The physical mechanisms of unlocking the "perfect" polarized carbon-electrolyte interface, which allowed to develop the supramolecular design of desired structures.
