Behavior of electrodes based on activated carbon P2 (Ener G2) wih additions of plain carbon black, as well as carbon black doped with silver nanoparticles have been studied. Depending on potential range and polarization direction the electrodes were found to reveal a capacitance close to double-layer or pseudocapacitance.

In this review electrochemical and structural data for the electrodes made of certain of perspective materials for supercapacitors are considered. These electrodes were made on the basis of high-dispersed carbon materials. The following materials were used: singlelayer and multilayer carbon nanotubes; reduced oxide of graphene; the carbide type activated carbon; polyacrilonitrile fibers treated by carbonization and activation; the activated carbon fibrous material; the activated carbon cloth; a composite of polyporphirine on carbon black; polyporhine of magnesium, electrodeposited on carbon paper; and a polyaniline composite with the singlelayer nanotubes, electrodeposited on carbon paper. The short review of techniques of synthesis of these electrode materials is presented. Comparison of capactance characteristics of these electrodes for the purpose of the recommendation of their use in certain types of electrochemical supercapacitors is carried out.
