Larger-scale pilot plant for VRFB electrolytes preparation
Original language description
Engineering development of new local storages of electricity as a modern tool of energy management tailored to efficient and smart electricity distribution is extensively required. It has been proven that the vanadium redox flow battery (VRFB), using different vanadium ions (oxidation state II, III, IV and V) in both half-cells, excels as the stationary energy storage in its sufficient capacity (kWh) proportional to the electrolyte volume, long lifetime and high efficiency. The specific capacity of vanadium electrolytes is low (in order of 100 Wh/L). Thus should be noted that the development of electrolyte production unit with sufficient daily capacity appears as very important step allowing scale-up and wider commercialization of the VRFB. V2O5 is inthe first phase dissolved in solutions of VII or VIII sulfates and H2SO4. Mostly the VIV is than reduced in membrane electrolyzer to lower oxidation states. The negative half-cell is very similar to the half-cells of VRFB (i.e., electrode
