Is a vanadium redox flow battery a promising energy storage system?

Perspectives of electrolyte future research are proposed. The vanadium redox flow battery (VRFB), regarded as one of the most promising large-scale energy storage systems, exhibits substantial potential in the domains of renewable energy storage, energy integration, and power peaking.

What is vanadium oxide?

Vanadium oxide (VO 2) is one of the phase change materials used as thermochromic smart window coating to cut off the energy consumption for regulating room temperature due to its near room temperature metal-insulator transition (MIT) and has attracted attention from academia and industry.

What is a suitable concentration of vanadium?

For the above reasons, the temperature window is limited in the range of 10–40 °C, with a concentration of vanadium limited to 1.5–2 M. Skyllas-Kazacos et al. recommended a suitable concentration of vanadium at 1.5 M or lower, and that the SOC should be controlled at 60–80 % when the concentration of ions was higher.

Does vanadium crossover control electrolyte capacity decay?

Skyllas-Kazacos et al. utilized physical methods for electrolyte but had unsatisfactory results (Fig. 16 a), which suggested that the capacity decay is not controlled only by vanadium crossover but side reactions.

Which term describes the migration law of vanadium ions?

The second term describes the migration law of vanadium ions, which is dominated by electric filed and ions concentration. The third term represents the migration flux caused by electrolyte convection, where v → is electrolyte convection velocity.

How much does a vanadium electrolyte cost?

The specific operational energy density of a VRFB cell is such that there is rational power density; hence, it is lower than the theoretical energy density. Therefore, the cost for the vanadium electrolyte lies in the range of 270 € (kWh) −1 mentioned to the useable capacity (König 2017).
