Abstract
U ovom radu konstruirani su simetrični superkondenzatori od ugljikovih elektroda u dva različita organska elektrolita: tetrabutilamonijevom tetrafluoroboratu (TBA–TFB) i tetraetilamonijevom tetrafluoroboratu (TEA–TFB) u acetonitrilu. Pomoću platinske pseudoreferentne elektrode simultano su praćeni procesi nabijanja i izbijanja na individualnim elektrodama kao i na cjelokupnom superkondenzatoru. Korištene su metode kronopotenciometrije i cikličke voltametrije. Iz dobivenih rezultata dobiveni su specifični kapaciteti superkondenzatora. Pokazalo se da superkondenzator s elektrolitom TEA–TFB ima veći specifični kapacitet od supekondenzatora s elektrolitom TBA–TFB zbog toga što je kation manji i dublje prodire u pore aktivnog materijala.
Abstract (english)
In this work, symmetrical supercapacitors made of two identical carbon electrodes in two different organic electrolytes: tetrabutylammonium tetrafluoroborate (TBA–TFB) and tetraethylammonium tetrafluoroborate (TEA–TFB) in acetonitrile, were constructed. By inserted platinum pseudoreference electrode, the charging and discharging processes were simultaneously monitored on the individual electrodes as well as for the whole supercapacitor cell. Specific capacitances of supercapacitors were obtained from testing of the individual electrodes by chronopotentiometry and cyclic voltammetry. It was demonstrated that the TEA–TFB electrolyte supercapacitor has a higher specific capacity than the TBA–TFB electrolyte supercapacitor because of the smaller cation that penetrates deeper into the pores of the active material.
