• reaction (HER) at the negative electrode [2][3][4]. The air oxidation of V2+ species can be completely prevented by keeping the negative tank under inert gas atmosphere. However, the HER at the negative electrode is almost unavoidable as the redox potential of V3+/V2+ (−0.26 V vs normal hydrogen electrode

• (NHE)) reaction is very close to HER (0 V vs NHE). To minimize the HER, the negative electrode surface structure should be tuned in such a way that it tends to preferably bind V3+/V2+ ions over H+ ions. Creating oxygen functional groups on the surface of the anode is one way to achieve this [5][6

• ]. Langner et al. have shown that on a functionalized electrode, in the presence of V3+, the HER is suppressed as the V3+ ions get preferentially bonded to the oxygen functional groups [6]. Furthermore, they proposed that it is essential to have at least 5% oxygen functionality on the surface of the carbon
