Review of the I−/I3− redox chemistry in Zn-iodine redox flow batteries …
One of the key parameters for RFBs is the volumetric energy density (E, W h L −1), meaning the capacity of storing energy in per liter electrolyte can be measured by the equation: (1) E = N C a F V n Where N is the number of electrons transfer in the redox couple transformation, C a is the lower concentration value in the cathode-side or anode …
