Original Abstract

Vanadium has several soluble oxidation forms which can be used as the oxidized and reduced side of an electrochemical cell. This is the basis of the so called redox flow battery. A redox flow battery is an applied technological system from which electrical energy is derived using the electrochemical reaction of the higher and lower oxidation state of a pair of solutions. Our aim was to carry out more fundamental studies of the redox processes on graphite electrodes in solutions of vanadium salts. The experimental setup was using a rotated disk electrode and voltammetric, and impedance measurements were performed.
