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.
Vanadium redox flow batteries (VRFBs) can effectively solve the intermittent renewable energy issues and gradually become the most attractive candidate for large-scale stationary energy storage. However, their low energy density and high cost still bring challenges to the widespread use of VRFBs.
In 1984, Skyllas-Kazacos and co-workers proposed the vanadium redox flow battery (VRFB). [26 - 28] To date, the VRFBs stand as the most commercially developed RFBs. [29 - 32] Generally speaking, a single battery system mainly consists of two electrodes, a membrane, two pumps, and two electrolyte tanks (Figure 1b).
As mentioned earlier, the penetration of vanadium ions through the membrane can trigger side reactions, resulting in decreased CE and a corresponding reduction in the cell's capacity. While the capacity loss per cycle may be minor, the cumulative irreversible capacity loss is significant, which can ultimately result in failure of VRFB.
Abstract: Vanadium redox flow battery (VRFB) systems complemented with dedicated power electronic interfaces are a promising technology for storing energy in smart-grid applications in which the intermittent power produced by renewable sources must face the dynamics of requests and economical parameters.
Subsequently, the vanadium ions participate in redox reactions on the electrode surface (Figure 1c), [27, 44 - 46] while electrons and protons transfer along the external circuit and the membrane, respectively, to ensure the electroneutrality of the overall system.

Because of their high capacity and appropriate structure, vanadium (V)-based materials make up a large proportion of the research on cathodes for rechargeable aqueous zinc–ion batteries (AZIBs). Unfortunately, as a result of catastrophic structural instability and the participation of highly active water, V-based batteries typically suffer from rapid capacity …
That arrangement addresses the two major challenges with flow batteries. First, vanadium doesn''t degrade. "If you put 100 grams of vanadium into your battery and you come back in 100 years, you should be able to recover 100 grams of that vanadium — as long as the battery doesn''t have some sort of a physical leak," says Brushett.
Vanadium batteries are nevertheless more cost efficient in the long run, considering their longer life cycle compared with other storage batteries. "A lithium battery can normally work for around 10 years, but a vanadium battery can run for 20-30 years," the battery raw-material analyst said. If calculated for the whole life cycle, the cost of a vanadium battery …

Commercial systems are being applied to distributed systems utilising kW-scale renewable energy flows. Factors limiting the uptake of all-vanadium (and other) redox flow batteries include a comparatively high overall internal costs of $217 kW −1 h −1 and the high cost of stored electricity of ≈ $0.10 kW −1 h −1.
Performance optimization and cost reduction of a vanadium flow battery (VFB) system is essential for its commercialization and application in large-scale energy storage. However, developing a VFB stack from lab to industrial scale can take years of experiments due to the influence of complex factors, from key materials to the battery architecture.
Aqueous zinc-ion batteries (AZIBs) are favorable competitors in various energy storage devices due to their high energy density, reassuring intrinsic safety, and unique cost advantages.
