Note on the parameterization of the constant-phase admittance element

Solid State Ionics, 1984
Abstract Some background is presented on the constant-phase admittance element, frequently used as part of a circuit for fitting immitance data on solid electrolytes. Several alternate ways of writing an expression for the constant-phase element are discussed and compared, and it is suggested that one particular parameterization seems preferably to ...

Effect of Electrolyte Contaminants and Surface Roughness on the Constant Phase Element

ECS Meeting Abstracts, 2020
The origin of constant phase element (CPE) to explain electrode/electrolyte interface is subject of debate in the literature. CPE behavior is generally attributed to the presence of reactivity, surface inhomogeneity, various crystal planes and atomic scale defects in the crystal; all these may lead to dispersion of local capacitance at the electrode/

Constant Phase Element in the Laplace Domain

Journal of The Electrochemical Society
The constant phase element (CPE) has long stood as an empirical construct bridging the gap between ideal capacitors and the complex reality of electrochemical phenomena. Despite its universal use in the modeling impedance spectra, the time-domain behavior however remains ambiguous yet, particularly under non-stationary ...

A generalized procedure for the coulostatic method using a constant phase element

Electrochimica Acta, 2017
Abstract The coulostatic method has been successfully used in the study of electrode processes. In the literature, the technique is explained on the premise that the step-charge is transferred to an ideal interfacial capacitance. Here, for the first time, we have generalized the coulostatic test method by considering a non-ideal interfacial ...

Relaxation spectra of the Warburg impedance and the constant-phase elements

Russian Journal of Electrochemistry, 2000
It is shown that there is indissoluble connection of impedances of constant-phase elements (CPE) with the presence, in a system, of a continuous spectrum of intrinsic frequencies inside a region where an impedance of CPE is observed. Such a connection exists in objects of any nature.

Analysis of Nonexponential Transient Response Due to a Constant‐Phase Element

Journal of The Electrochemical Society, 1994
To characterize electrical losses of fuel cells or batteries, impedance spectroscopy (IS) or current interruption (CI) can be used. Analysis and parameter determination of impedance data is widely used. The system under study is usually represented by an equivalent circuit from which the system parameters can be determined.

Constant phase elements, depressed arcs and analytic continuation: A critique

Journal of Electroanalytical Chemistry, 2008
The connection between the constant phase element (CPE) and the depressed arcs often observed in the Nyquist plane is critically analyzed using the analytic continuation principle enunciated earlier by the author. A major inconsistency is pointed out in a model presently used to explain these depressed arcs.
