Vanadium ion concentration, supporting electrolytes concentration, environmental temperature, and even the difference between positive and negative solution can all impact the viscosity, thus influencing the battery performance.
For the above reasons, the temperature window is limited in the range of 10–40 °C, with a concentration of vanadium limited to 1.5–2 M. Skyllas-Kazacos et al. recommended a suitable concentration of vanadium at 1.5 M or lower, and that the SOC should be controlled at 60–80 % when the concentration of ions was higher.
Skyllas-Kazacos et al. utilized physical methods for electrolyte but had unsatisfactory results (Fig. 16 a), which suggested that the capacity decay is not controlled only by vanadium crossover but side reactions.
The results showed that 2.4 M vanadium remained stable for 10 days in a mixed acid electrolyte containing 6.0–7.0 M Cl − and 2.0–3.0 M SO 42− (Fig. 6 e), with no chlorine gas observed at 1.7 V cut-off voltage.
