Fig. 4 presents the low and high temperature stability of the four types of the vanadium electrolytes (V 2+, V 3+, VO 2+ and VO 2+) with different total vanadium concentrations (0.4–2.2 M) and sulfuric acid concentrations (initial VO 2+ electrolyte, 1.5–3.0 M) over a wide temperature range from −35 °C to 60 °C.
Based on the data of static temperature stability tests, the vanadium concentration range in which the V (II), V (III), V (IV) electrolytes can be stable at −20 °C and the V (V) can be stable at 50 °C simultaneously with different sulfate concentrations (1.0–5.0 M) and chloride ion concentrations (3.0–8.0 M) are shown in Fig. 2.
Vanadium flow batteries (VFB) offer an ideal solution to the issue of storing massive amounts of electricity produced from intermittent renewables. However, the historical challenge of high thermal precipitation of V 2 O 5 from VO 2+ (∼50 °C for 1 day) represents a critical concern.
In the static temperature stability test, we found that when the vanadium concentration is 1.2 M or 1.6 M, a relative broad temperature stable range and an acceptable energy density can be achieved. Such a conclusion led us to explore the vanadium concentrations between 1.2 M and 1.6 M.
Vanadium concentration ranges in which the V (II), V (III), V (IV) and V (V) electrolytes can be stable at −20 °C and 50 °C respectively with different sulfate concentrations (1.0–5.0 M) and chloride ion concentrations (3.0–8.0 M).
