Resistor-capacitor (RC) pairs, i.e. a resistor in parallel with a capacitor, represent a basic circuit element for such an ECM. To account for distributions of parameters while keeping the number of elements low, the empirical ZARC circuit element, where the capacitor in an RC element is replaced by a constant phase element, has been proposed . Nonetheless, such an empirical ECM still contains only a subset of the parameters necessary for obtaining accurate physical properties of the different materials and interfaces. Alternatively, a more data-driven approach can be followed for an improved ECM parametrization. It has been shown that the electrochemical circuit elements commonly used to describe batteries in ECMs can be modelled accurately as distributions of RC elements . Thereby the impedance response of an RC element is used as a kernel for the deconvolution of EIS spectra to obtain a distribution of relaxation times (DRT). DRT is often used as a substitution of ECM. The supplemental use of DRT and ECM is rather uncommon despite the evident complementarity of the two techniques .
