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.
To address this specific gap, Vanadium Redox Flow Batteries (VRFBs) have emerged as a powerful and promising technology tailored for large-scale energy storage , . The defining characteristic of a VRFB is the unique decoupling of its power and energy capacity.
Vanadium permeability Diffusion of the V ions from one half-cell to the other leads to discharge of the battery and, thus, determines the energy storage time of the battery. Extensive research has shown that the cationic membranes are susceptible to V permeability due to their attraction of the V species.
Exposure of the polymeric membrane to the highly oxidative and acidic environment of the vanadium electrolyte can result in membrane deterioration. Furthermore, poor membrane selectivity towards vanadium permeability can lead to faster discharge times of the battery. These areas seek room for improvement to increase battery lifetime.
Thus, the capacity decay of Iron-vanadium flow batteries can be mainly attributed to the ion diffusions across the membrane. In the main, the capacity retention ability of VFB is superior to that of IVFB, because the VFB capacity is not only higher after 500 cycles, but also without unexpected fluctuation during the whole testing.
When the battery is being discharged, active species on the negative side oxidize, releasing electrons that flow through an external circuit to the positive side, causing the species there to be reduced. The flow of those electrons through the external circuit can power the grid.
