PACS numbers: 68.37.Hk, 68.43.Mn, 81.05.Rm, 82.45.Fk, 82.45.Gj, 82.45.Yz, 82.47.Uv

The article presents the results of electrochemical and morphological investigations of nanoporous carbon as an electrode material for electrochemical capacitors. Nanoporous carbon material is obtained from raw vegetable materials via carbonization and subsequent activation by sodium hydroxide. The optimum conditions of activation of nanoporous carbon are set, at which the maximum specific capacity of electrochemical capacitors formed on its base is 140 F/g. As shown, the state and morphology of the developed surface greatly affect the value of specific capacity.

Keywords: nanoporous carbon, aqueous electrolyte, capacity, voltage drop
