| Annotation | The results of electrochemical studies of nanoporous carbon as an electrode material for electrochemical capacitors are presented in the work. Nanoporous carbon material (NCM) is obtained from raw materials of plant origin by its carbonization and subsequent activation in potassium hydroxide. It is established that there is an optimal ratio 1 : 1 between content of KOH and carbon material at chemical activation, while the maximum specific capacity of NCM is 180 F/g. An equivalent electrical circuit, which allows modeling the impedance spectra in the frequency range of 10 – 3-105 Hz, is proposed and a physical interpretation of each element of the electrical circuit is presented. |
