The structural, morphological and electrochemical properties of porous carbon materials obtained by carbonization of saccharides (glucose, lactose, sucrose) at 400 °C and their subsequent thermooxidation activation at 800 and 1000 °С were investigated using methods of small-angle X-ray scattering, low-temperature porometry, galvanostatic cycling and cyclic voltammetry. It is set that the materials obtained have developed porosity (more than 0.6) and high specific surface (from 350 to 657 m2/g). The specific capacity of the electrochemical capacitors formed on their basis is 94-160 F/g at discharge current of 10 mA.
