New Alkalescent Electrolyte Chemistry for Zinc-Ferricyanide Flow Battery.

Alkaline zinc-ferricyanide flow batteries are efficiency and economical as energy storage solutions. However, they suffer from low energy density and short calendar life. The strongly alkaline conditions (3 mol L-1 OH-) reduce the solubility of ferri/ferro-cyanide (normally only 0.4 mol L-1 at 25 oC) and induce the formation of zinc dendrites at the anode. Here, we
