Advanced secondary batteries have been developed as electrical energy storage systems for use in electrical utility load-levelling and stand-alone photovoltaic installations. Among them, the redox flow system based on aqueous iron and chromium redox couple is one of the most advanced. An important key to its feasibility is electrode fabrication. Woven and non-woven fabrics of carbon fibers have been used as thin but three dimensional electrodes of the redox flow system in view of their electric conductivity, chemical stability, and economy. One of the electrochemical problems of iron-chromium redox battery related to the electrode is the slow reaction rate of reduction and oxidation of chromium complex ion. As the electron transfer rate of chromium complex ion is lower than that of iron ion, the voltaic efficiency of the battery tends to decrease.
