Note that in this electrolyte, effectively a mixture of two redox-active species (reduced and the adduct) has formed. As per our prior work on mixed organic redox-active species , when the potential separation between two mixed species is over 300 mV, the concentration of the first redox species is consumed before the second redox event begins. This means that for the present case, the capacity at each plateau can be directly correlated with the corresponding species concentration. If the potential separations were less than 300 mV, it is expected to have a certain degree of oxidation of the adduct from the start of the discharge phase. In such a case, a modeling scheme such as the one developed in our prior work must be used for the accurate prediction of the concentrations.
