Challenges of VRB for Commercialization<br />

‣ poor electrolyte stability and less solubility lead<br />

to lower energy density<br />

‣ Low selectivity to the vanadium ions for ion exchange<br />

membrane lead to the Unbalance of vanadium ions<br />

and water , and the capacity degradation after long<br />

operation time<br />

‣ Low rated operation current density lead to high<br />

material cost<br />

‣ High cost of the ion exchange membrane<br />

Limited the RFB practicability seriously
