Basics of Electrochemical Impedance Spectroscopy (EIS) I A Comprehensive Overview

We provide an overview of the basics of electrochemical impedance spectroscopy, highlighting key topics that may require further review. Links to the corresponding videos are included for deeper exploration. This compilation of summaries from our 'Basics of EIS' series supports the Electrochemical Impedance Spectroscopy lectures for the Master's program in Chemistry and our research student interns at Ruhr University Bochum (RUB) in Germany.

We provide detailed explanations of the key terms and experimental examples to help viewers understand the concepts, fill in gaps, and promote connections within their knowledge maps. In this way, we hope to prepare our students and interested electrochemistry enthusiasts for more advanced topics in EIS, such as those covered in the Electrochemistry I and II courses at RUB. #EIS #impedance #electrochemistry #education written and presented by Sebastian Reinke and Julia Linnemann filmed and edited by Christian Wunderle Website: https://shape-ec.ruhr-uni-bochum.de/ Acknowledgements: We are grateful for financial support from the Stiftung Mercator (project [e-Speicher]3, project ID 18023) and the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under CRC 247 project-ID 388390466 (project A09).
