Abstract
A comparative study of the characteristics of high-molecular organic matter (cotton lint) subjected to pyrolytic carbonisation under conditions of high-intensity microwave radiation in various gaseous media (N2, CO2, Ar) has been conducted. The methods employed included the determination of adsorption activity through the use of a methylene blue indicator, X-ray fluorescence analysis, transmission electron microscopy with microanalysis, and X-ray phase analysis. Electrodes derived from carbon materials produced through microwave carbonisation with varying gases were constructed, and symmetric cells were assembled in accordance with the two-electrode configuration. The electrochemical properties were investigated using cyclic voltammetry and galvanostatic charge-discharge methods. The results demonstrated that the materials obtained using a CO₂ gaseous medium exhibited the most optimal characteristics.
