Why are there no flow batteries with symmetric ferrocyanide electrolytes?
If you have looked into flow batteries for any length of time, you will have found that the ferrocyanide/ferricyanide redox couple ( [Fe(CN)6] 4−, Fe(CN)6] 3−) is one of the most widely used in the field. This is because this redox couple has very high redox stability, great kinetics, significant solubility (0.7-1.2M depending on the exact salts used) and a redox potential that is lower to that of the Fe2+/Fe3+ redox couple (+0.22V and +0.5V respectively Vs saturated Ag/AgCl), with […]
