## Summary

In this tutorial review by Subrata Karmakar, the focus is on the fundamental theoretical foundations, operational principles, and practical applications of impedance spectroscopy in both electroceramics and electrochemical research. The technique allows for the disentanglement and independent characterization of various contributions to the impedance, admittance, dielectric properties, and conductivity characteristics of electroceramic materials across different frequencies and temperatures. Specifically in polycrystalline materials, factors such as bulk or grain resistance/capacitance, grain boundaries, and sample-electrode interface effects contribute to the overall impedance profile. Electrochemical impedance spectroscopy (EIS) plays a crucial role in investigating charging kinetics, diffusion processes, and mechanical impacts within various electrochemical systems used in energy storage (e.g., supercapacitors, batteries), corrosion resistance, chemical sensing, bio-sensing applications, diagnostics etc. The understanding of kinetic control mechanisms,mass transport phenomena,and diffusion control through EIS spectra is essential for practical implications in these fields. The review underscores that impedance spectroscopy techniques are effective tools for explaining and simulating complex behaviors observed in electroceramic materials and electrochemical systems.By deconvoluting these contributions through detailed analysis,researchers can gain a comprehensive understanding of the functionality of polycrystalline electroceramic materials. Overall,this comprehensive review aims to provide valuable insights for senior researchers engaged in interdisciplinary fields involving both electrochemical and ceramics research while also serving as a foundational resource for junior researchers entering these areas of study.
