Summary. Since the original all-vanadium flow battery (VFB) was proposed by UNSW in the mid-1980s, a number of new vanadium-based electrolyte chemistries have been investigated to increase the energy density beyond the 35 Wh l −1 of the original UNSW system. The different chemistries are often referred to as Generations …

The following chapter reviews safety considerations of energy storage systems based on vanadium flow batteries. International standards and regulations exist generally to mitigate hazards and improve safety. Selected standards are reviewed, especially where they give explicit advice regarding flow batteries.
Early government and industry funding led to a large research and development effort at UNSW that formed the foundations of the vanadium battery industry that we see today. This paper presents an historical overview of the research, development, and early field trials of the All-Vanadium Flow Battery at UNSW from 1983 to 2020.
Among them, the VRFB is the most well-studied and developed flow battery technology for large-scale energy storage due to the use of vanadium in its two electrolyte solutions. This therefore prevents cross-contamination of electrolytes, a major challenge, which is seemingly unavoidable in other flow battery chemistries.
