Technical FAQs 4

Can a vanadium redox flow battery be a high-performance battery?

Vanadium redox flow battery (VRFB) has garnered significant attention due to its potential for facilitating the cost-effective utilization of renewable energy and large-scale power storage. However, the limited electrochemical activity of the electrode in vanadium redox reactions poses a challenge in achieving a high-performance VRFB.

What is vanadium redox flow battery (VRFB)?

Vanadium redox flow battery (VRFB) has emerged as a key technology for addressing clean energy utilization issues, owing to its advantages of high safety, extended life, and high efficiency [19, 20]. In VRFB, the role of the electrode is essential for redox reactions, significantly influencing the battery’s overall efficiency [21, 22].

Can LA-based perovskite be used as a catalyst for vanadium redox reactions?

Herein, we successfully fabricated La-based perovskite of LaBO 3 (B = V, Cr, Mn, Fe, Co) as catalyst of graphite felt (GF) electrode for vanadium redox reactions (Fig. 1) and uncovered their underlying catalytic mechanisms. For perovskites, oxygen-containing functional groups are formed at B-O binding to boost the adsorption of vanadium ions.

Can graphite be used as a positive electrode for vanadium redox flow batteries?
