How stable is a vanadium electrolyte?
The stability of the vanadium electrolyte is also highly dependent on the temperature. Temperatures above 40 °C in the positive electrolyte and below 10 °C in the negative electrolyte commonly induce formation of solid V 2 O 5 and VSO 4 precipitates, respectively. [ 2]
Why does the concentration of vanadium vary during battery operation?
This dependence is of critical importance during battery operation; since the SOC of the solution for each half-cell electrolyte could be changed, the vanadium concentrations may differ accordingly because of the ionic diffusion processes across the membrane and thus the solution conductivities vary.
