Tailoring of surface topography of carbon electrodes for supercapacitors using plasma technologies

In this work, we address the issue of controlled modification of the surface topography of carbon materials when subjected to oxygen-based plasma treatment, and we investigate the resulting enhanced surface area as a mean of controlling the capacitance of supercapacitors. It is shown that carbon layers with porous of controllable nanoscale size can be tuned from nanoporous to mesh-like employing atmospheric plasma torch deposition technology and following appropriate plasma processing. The nanoscale carbon processing is optimized to form surface topographies that promote carbon wettability with electrolyte. Three dimensional structures fabricated on carbon are chosen as appropriate surfaces for the enhancement of the capacitance of supercapacitors. This fact underlines the potential application of the proposed technique for fabricating electrolyte-wetted carbon electrodes for supercapacitorsFizikos katedraVytauto Didžiojo universiteta
