Today we celebrate the 9th Open Access Publication from project PULSELiON, by presenting the journal article “Enhanced Porous Electrode Theory Based Electrochemical Model for Higher Fidelity Modelling and Deciphering of the EIS Spectra”, which has been published already some time ago in the #Journal of The Electrochemical Society, Volume 171, Number 8 on 27 August 2024.
Electrochemical impedance spectroscopy (EIS) is essential for non-invasive battery characterization. This paper addresses the challenge of adequate interpretation of EIS spectra, which are often complicated by overlapping internal phenomena occurring on similar time scales.
The work presents, for the first time, a high-fidelity numerical time-domain electrochemical model that can virtually replicate experimental EIS spectra with three superimposed high-frequency semicircles, a transition to the diffusion tail at elevated imaginary values, and a tilted diffusion tail at low frequencies.
We are proud of this achievement within project PULSELiON, thanks to the authors Igor Mele, Klemen Zelič and Tomaž Katrašnik of the University of Ljubljana, Faculty of Mechanical Engineering.
