10.4 Summary
The properties of the negative half-cell solutions are critical in the design and
optimisation of the vanadium redox battery, especially for low-temperature
operation where the solubilities of V(II) and V(III) sulphates will inuence
the maximum practical vanadium ion concentration in the VRB electrolyte.
The selected composition of the VRB electrolyte will determine the solution
properties such as density, viscosity and conductivity and these in turn are
also inuenced by temperature.
Accurate knowledge of solution density is important in calculating theo-
