Abstract

Results of the study of micro-mesoporous carbonaceous materials with characteristic turbostratic carbon structure and specific surface area of 1000 - 2000 m2/g were shown. These materials were derived by use the method of chemical activation of plant fiber represented by apricot and walnut shells, and also by the rice husk. Derived carbon-containing samples were used to manufacture composite electrode materials, which were subsequently subjected to electrochemical testing in the composition of capacitors with a double electric layer. The possibility of using these electrode materials assembled as a part of composite electrodes of supercapacitors was studied; the maximum specific electric capacity of which amounted to 160 F/g.
