IDTechEx Issues a Report on RFB Technologies

IDTechEx has published a report on the detailed analysis of the main RFB technologies currently available or under development, beginning with the most adopted and investigated Redox Flow Batteries (RFB), the Vanadium Redox Flow Batteries (VRFB).

IDTechExInitially studied by NASA, and further developed in the 1980s by the research group led by Maria Skyllas-Kazacos at New South Wales in Australia, the Vanadium redox flow battery (VRFB) are today the most studied and manufactured technology within the redox flow battery technology. Besides the different type of RFBs, the vanadium technology (and similarly the All-Iron RFB) employs the same electro-active species (vanadium) in both electrolytes, with different oxidation states. The following reactions take place during charge and discharge of VRFBs:

The low round-trip efficiency and the high cost of vanadium (directly affecting the cost of electrolyte) are two of the main VRFBs’ drawbacks. The electrolyte alone accounts for 30% to 40% of the overall technology cost. To reduce the effect of vanadium cost on the overall system, an increasing number of companies started collaborations with vanadium mining companies. The collaborations aim to improve the vanadium electrolyte performances by increasing the vanadium concentration (moles of Vanadium per liter of electrolyte). This would allow reaching the higher energy density of the battery, and the reduction of the cost.
