Abstract: 

In this paper we investigate carbon materials prepared from different organic raw materials of vegetable nature by the method of pyrolysis. Properties of obtained carbon substances are established by the methods of impedance spectroscopy, voltamperometry, and chronoamperometry. Starting from the data of electron paramagnetic resonance, impedance spectroscopy and an analysis of the Regon diagrams it is concluded that the obtained carbon materials contain carbon nanostructures in the form of bungles of multiwall nanotubes. On the basis of the obtained vegetable-based carbon materials laboratory patterns of supercapacitors with an aqueous alkaline electrolyte were fabricated and investigated.
