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.
In the 1980s, the University of New South Wales in Australia started to develop vanadium flow batteries (VFBs). Soon after, Zn-based RFBs were widely reported to be in use due to the high adaptability of Zn-metal anodes to aqueous systems, with Zn/Br2 systems being among the first to be reported.
Besides sulfuric acid, there are other supporting electrolytes in the vanadium electrolyte. The electrolyte of vanadium batteries usually consists of sulfuric acid as the main component. However, to enhance the conductivity and stability of the electrolyte, other supporting electrolytes may be added, such as ammonium salts and chlorides.
