The vanadium flow battery (VFB) as one kind of energy storage technique that has enormous impact on the stabilization and smooth output of renewable energy. Key materials like membranes, electrode, and electrolytes will finally determine the performance of VFBs.
Unlike other RFBs, vanadium redox flow batteries (VRBs) use only one element (vanadium) in both tanks, exploiting vanadium’s ability to exist in several states. By using one element in both tanks, VRBs can overcome cross-contamination degradation, a significant issue with other RFB chemistries that use more than one element.
In an attempt to combine the advantageous features of the VRFB and ICRFB systems, in this work, an innovative vanadium-chromium RFB (V/Cr RFB) by adopting the V (VI)/V (V) with the low-cost Cr (III)/Cr (II) redox couples has been designed and fabricated.
By using one element in both tanks, VRBs can overcome cross-contamination degradation, a significant issue with other RFB chemistries that use more than one element. The energy density of VRBs depends on the concentration of vanadium: the higher the concentration, the higher the energy density.
A 1 kW/1 kWh VRB stack has been successfully demonstrated using the new mixed-acid electrolyte, showing significantly improved energy density and temperature stability. In addition, a low-cost separator for VRB applications has been successfully developed, which can further reduce the cost of VRB systems.
