Abstract
The article discusses the development of the technology for manufacturing supercapacitor electrodes from industrially produced carbon nanotubes with a specific surface area of 109.6 m2/g, with the aim of further application in the manufacture of carbon electrodes for self-charging supercapacitors. The electrochemical characteristics of carbon nanotube electrodes were studied in a symmetrical two–electrode cell using cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy. It was shown that the specific capacitance of the electrode in the organic electrolyte 1-butyl-3-methylimidazolium trifluoromethane sulfonate:propylene carbonate (volume ratio 3:1) was 9.1 F/g.
