On the physical interpretation of constant phase elements

Solid State Ionics, 2009
Abstract Complex impedance spectra of ion-conducting lithium borate network glasses are used to study the deformed shape of impedance semicircles which are usually described by a parallel circuit of an ohmic resistor and a phenomenological Constant Phase Element (CPE). Based on the Concept of Mismatch and Relaxation (CMR) of Funke et al.

Designing constant phase elements of complement order

Analog Integrated Circuits and Signal Processing, 2018
Once designing analogue fractional-order function blocks, the capacitive and/or inductive fractional-order elements (FOEs), also referred to as constant phase elements, being defined with their fractional order $$\alpha$$

Experimental technique for estimating the dispersion coefficient of a constant phase element

2011 20th European Conference on Circuit Theory and Design (ECCTD), 2011
We report an experimental technique for estimating the dispersion coefficient α of a constant phase element (CPE). The method employs using a setup to excite the impedance under consideration via a periodic triangle-wave current I(t). Measuring the 50% rise time of the developed voltage V (t) then enables finding α using a pre-calculated Table ...

Constant-Phase-Element Behavior Caused by Resistivity Distributions in Films

Journal of The Electrochemical Society, 2010
CPE behavior may be attributed to the distribution of physical properties in films, in the direction normal to the electrode surface. Numerical simulations were used to show that, under assumption that the dielectric constant is independent of position, a normal power-law distribution of local resistivity is consistent with the Constant-Phase Element ...

On the efficient simulation of electrical circuits with constant phase elements: The Warburg element as a test case

International Journal of Circuit Theory and Applications, 2018
SummaryThe constant phase Element (CPE) concept naturally emerges as a model for describing a range of electrical phenomena where ionic diffusion is involved. We suggest a new method for modelling the transient behavior of electrical circuits that contain CPE elements.

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/
