摘要：

The redox reactions of vanadium ions in sulfuric acid, which are used for anolyte and catholyte in a redox flow battery, have been investigated on a GRC (graphite reinforcement carbon) electrode. Two types of carbon fiber electrodes (GF-20 and BW-309) have been evaluated for the battery electrode. As a result, the BW-309 was found to be best. Cyclic voltammetry has been used to estimate electrode reaction rate constants of the ions on a GRC electrode and two carbon fiber electrodes and to determine the suitable concentration of sulfuric acid for vanadium redox reactions in the battery. A charge-discharge experiment of V-V system in 2 M (mol dm-3) sulfuric acid solution has also been carried out on the carbon cloth (BW-309) electrode.
