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.
The membranes employed in vanadium flow batteries can be grouped into ion exchange membranes and physical separators; however, this topic will only focus on ion exchange membranes .
All-vanadium redox flow batteries use V (II), V (III), V (IV), and V (V) species in acidic media. This formulation was pioneered in the late eighties by the research group of Dr Maria Skyllas-Kazacos as an alternative to the Fe/Cr chemistry originally proposed by NASA.
Skyllas-Kazacos et al. developed the all-vanadium redox flow batteries (VRFBs) concept in the 1980s . Over the years, the team has conducted in-depth research and experiments on the reaction mechanism and electrode materials of VRFB, which contributed significantly to the development of VRFB going forward , , .
As an important branch of RFBs, all-vanadium RFBs (VRFBs) have become the most commercialized and technologically mature batteries among current RFBs due to their intrinsic safety, no pollution, high energy efficiency, excellent charge and discharge performance, long cycle life, and excellent capacity-power decoupling .
It adopts the all-vanadium liquid flow battery energy storage technology independently developed by the Dalian Institute of Chemical Physics. The project is expected to complete the grid-connected commissioning in June this year.
