Carbon electrode materials for electric double-layer supercapacitors have been investigated. A technology of atmospheric plasma torch in the mixture of C2H2+Ar gases was used for the deposition of 200 – 300 cm thick coatings of activated carbon with a high effective surface area on the surface of stainless steel 1X18H9T substrates. The ratio of Ar/C2H2 was verified in the range 15 – 55. The electrical characteristics of supercapacitors were correlated with the properties of carbon coatings registered by X-ray diffraction, scanning electron microscopy and Raman scattering spectroscopy analysis techniques.

Badano materiały elektrod węglowych dla dwuwarstwowych superkondensatorow. Zastosowano technologi. palnika plazmy atmosferycznej w gazowej mieszaninie C2H2+Ar do osadzania powłok aktywnego węgla o grubości 200 -300 cm na powierzchniach substratow ze stali nierdzewnej 1X18H9T. Stosunek Ar/C2H2 zosta. ustalony w zakresie 15 - 55. Charakterystyki elektryczne superkondensatorów zostały skorelowane z właściwościami powłok węglowych zarejestrowanymi przy użyciu dyfrakcji rentgenowskiej, skaningowej mikroskopii elektronowej oraz spektroskopii ramanowskiej.
