The electrochemical properties of C/MnO₂ composite materials in 1 M sodium sulfate solution were investigated using the methods of cyclic voltammetry, galvanostatic charge-discharge and impedance spectroscopy. It was shown that the capacitive characteristics of the electrodes depend on the nature and the method of obtaining manganese oxide nanoparticles. It was established that the material containing manganese oxide obtained using isoamyl alcohol as a reducing agent has high electrochemical characteristics.

The electrochemical characteristics of the electrode material based on activated “NORIT B Test EUR” carbon in 1 M sodium sulfate solution were evaluated by cyclic voltammetry, galvanostatic charge-discharge curves, and impedance spectroscopy. It is established that this material has low resistance, and the specific capacity of the electrode was 45 F/g.
