2024年8月20日 · In this work we propose a generalization of this network by considering the non-ideal fractional capacitive element, also known as constant phase element (CPE), as the energy storage component. The CPE’s impedance is given by Zc(s) = 1/(Cαsα), where Cα > 0 and 0 α ⩽ 1, and offers an extra degree of freedom compared to the ideal ...

In electrochemical impedance spectroscopy (EIS), constant phase elements (CPE) are used to model imperfect capacitive behavior of electrical systems. The impedance of a constant phase. Here, is angular frequency and and are frequency-independent constants. . is imaginary number called iota. Also 㘆⯾. Here, is the capacitance.
In this case, the double layer capacitance is replaced by a constant-phase element (CPE) attributed to RC transmission line effects, since it is distributed along a porous electrode/membrane interface.

Several techniques can be used to experimentally determine the interfacial capacitance of an electrode, which is a crucial parameter used for quantifying the efficiency of supercapacitors. However, the values obtained from cyclic voltammetry can be significantly different from those extracted from electrochemical impedance spectroscopy analysis.
Here I present a formula which converts a constant phase element (CPE) to its equivalent capacitor. Electrochemical imped-ance spectroscopy is capable of resolving a complex electrochemical processes into its faradaic and non-faradaic elements, and the non-faradaic process is frequently described as a CPE in place of a capacitor due to the non ...
