All-vanadium redox flow battery (VRFB), as a large energy storage battery, has aroused great concern of scholars at home and abroad. The electrolyte, as the active material of VRFB, has been the research focus. The preparation technology of electrolyte is an extremely important part of VRFB, and it is the key to commercial application of VRFB.
Moreover, in comparison to a commercialised vanadium redox flow battery, the synthesized flow battery based on ionic liquid excels in the replacement of acid–base (H 2 SO 4, HCl) systems, with a novel, green ionic liquid based electrolyte.
Currently, commercial vanadium electrolytes are primarily H 2 SO 4 (2.5–3.5 mol/L) solutions dissolving 1.5–2 mol/L vanadium, with energy densities typically around 25 Wh/L, significantly lower than Zn mixed flow batteries, which can achieve energy densities up to 70 Wh/L [10, 20].
