The main aim of this research is to show influence of different hydroxides, applied in carbon materials activation process on the electrochemical properties of activated carbon samples. The carbon material samples were prepared by hydrothermal treatment of sucrose and thermally activated using KOH, NaOH and LiOH by chemical activation method. The electrochemical properties of the obtained carbon material samples were examined by cyclic voltammetry and electrochemical impedance spectroscopy and correlated to their physicochemical properties. Investigated samples showed characteristic capacitor-like behavior. The best result of specific capacitance was obtained for the sample synthesized treated by KOH, while the increase in capacitance follows the arrangement of the growth of ionic radius of a metal from an alkali which is used for activation. Dependence on the type of hydroxide is due to differences in the radii of a metal. The alkalis with larger radii of metal produce wider pores and... consequently the structure of a porous layer become more accessible and available to the charge transfer of capacitive response.
