Does concentration of vanadium affect electrolyte stability?

Wen et al. state that the electrolyte stability is most strongly affected by the relationship between the concentration of vanadium and H 2 SO 4 and that an increase in the concentration of H 2 SO 4 attenuates the precipitation of the V (V) ions but that a very high concentration impacts on the precipitation of the ions.

Do vanadium ions have high coulombic and energetic efficiencies?

The data obtained, in general, agreed with those of Sun et al. and Zhang et al. , which pointed to low permeability of vanadium ions, which resulted in high coulombic and energetic efficiencies, higher than those obtained for Nafion membranes.

Why are innovative membranes needed for vanadium redox flow batteries?

Innovative membranes are needed for vanadium redox flow batteries, in order to achieve the required criteria; i) cost reduction, ii) long cycle life, iii) high discharge rates and iv) high current densities.
