Are vanadium redox flow batteries viable?
Among these systems, vanadium redox flow batteries (VRFB) have garnered considerable attention due to their promising prospects for widespread utilization. The performance and economic viability of VRFB largely depend on their critical components, including membranes, electrodes, and electrolytes.
What is a vanadium redox flow battery (VRFB)?
Among the various RFBs, the vanadium redox flow battery (VRFB) has the specific advantage of deploying the same element, i.e., vanadium in different oxidation states in both negolyte and posolyte. However, its major unmet concern is the poor charge retention during cycling, attributed to cross-contamination of vanadium across the separator.
Are all-vanadium RFB batteries safe?
As an important branch of RFBs, all-vanadium RFBs (VRFBs) have become the most commercialized and technologically mature batteries among current RFBs due to their intrinsic safety, no pollution, high energy efficiency, excellent charge and discharge performance, long cycle life, and excellent capacity-power decoupling .
How do VRFB membranes improve battery performance?
In recent years, the membrane research community has adopted different strategies to counter the cross-contamination of the vanadium ions between the electrodes and boost the overall performance of the battery. In this review, we will focus on the various approaches developed for the advancement of VRFB membranes.
What is a redox flow battery?
Redox flow batteries (RFBs) are one of the hopes for grid energy storage applications. Among the various RFBs, the vanadium redox flow battery (VRFB) has the specific advantage of deploying the sam
Are redox-active vanadium species a suitable separator for VRFB?
Perfluorosulfonic acid-based cation exchange membranes (CEMs) are the preferred separators for VRFB. Nevertheless, for the negatively charged matrix of CEMs, redox-active vanadium species are the counterions and easily diffuse through, leading to capacity decay. To counter the crossover, the benefit of Donnan exclusion has been considered.
