Modeling and applications of Electrochemical Impedance Spectroscopy (EIS) for Zinc-ion batteries

Electrochemical Impedance Spectroscopy (EIS) has emerged as a valuable tool for evaluating secondary batteries due to their efficiency and accuracy. However, interpreting the multifaceted impedance spectra derived from EIS demands a comprehensive grasp of the electrochemical context. This study focuses on devising and applying an Electrochemical Impedance Spectroscopy (EIS) model customized specifically for deciphering the intricacies of zinc-ion batteries. The model construction is tailored to the battery's complexities, enabling extraction of circuit elements that faithfully depict the system's dynamics. Moreover, this research investigates the relationship between parameters of the governing equations. Through experimental validation employing real-time EIS measurements from a zinc-ion battery prototype, the reliability and efficacy of the proposed model are confirmed. This validated model not only enhances our understanding of zinc-ion battery behavior but also propels advancements in utilizing this technology across various energy storage applications.
