Second HarmonicNonlinear Warburg Admittance AnalysisEliminates Information Loss from Linearization in Traditional EIS:Theory and Experimental Validation

Abstract Low-frequency impedance or admittance experiments of reversible redox couples in well-supported quiescent electrolyte are normally analyzed using a linearized semi-infinite Warburg element with a single lumped parameter. Because each species of a redox couple has a disti...
