The electrical and chemical characteristics of nanocomposite materials based on carbon black for double-layer supercapacitors were investigated. It was shown that the highest values of the specific capacitive characteristics were obtained for carbon material SP4 which has the largest specific surface area (total capacity 228 F/g, reversible capacity 162 F/g). The results obtained in the work show the relevance of the problem under consideration and the necessity to continue the research to supplement the obtained experimental data for the pore distribution of materials in order to determine the influence of porosity on the physical and chemical characteristics.
