Реферат: Electrochemical characteristics of nanocomposites synthesized using carbon black and a pyrocarbon matrix were analyzed. The study was carried out by means of cyclic voltammetry in a three-electrode cell with a 1 M solution of sulfuric acid as the electrolyte, and commercial porous carbon Norit DLC Supra 30 as the reference sample. At lower specific surface areas of the materials under consideration, nanocomposite samples had higher specific capacitance values. The electrodes prepared using carbon nanocomposites were shown to possess good cyclic stability and a higher rate capability as compared to the electrode based on the commercial porous carbon. When the potential sweep rate was raised from 5 to 120 mV/s, the specific capacitance of nanocomposite samples decreased by 44%, whereas the sample containing commercial carbon lost more than 75%. In addition, it was found that nanocomposite with a higher content of pyrocarbon has a higher capacitance at a smaller specific surface area.
