Vanadium redox flow batteries (VRFBs) have emerged as a leading solution, distinguished by their use of redox reactions involving vanadium ions in electrolytes stored separately and circulated through a cell stack during operation. This design decouples power and energy, allowing flexible scalability for various applications.
The report highlights that thermal runaway remains a critical risk and that 72% of system-level defects involve fire safety components. In contrast, vanadium flow batteries, which are non-flammable and thermally stable by design, offer a safer and more predictable option for stationary energy storage applications.
A vanadium/air redox flow battery (VARFB) was designed utilizing vanadium and air as the redox pairs to enhance weight-specific power output. Operating at 80 °C, the VARFB achieved both high voltage and energy efficiencies.
Additionally, a higher mass flow rate can improve the utilization of vanadium ions, further contributing to the observed increase in VRFB capacity as the stoichiometric number rises. This relationship highlights the significance of optimizing both stoichiometric factors and flow dynamics to enhance the performance of vanadium flow batteries.
