EIS Workshop
Goal
This workshop is designed to provide a foundational understanding of Electrochemical Impedance Spectroscopy (EIS), with a focus on practical insights. Participants will learn:
- Develop a basic understanding of EIS and its principles
- Explore the physical origins of impedance (derived from measurements of electrical components)
- Learn how to model electrochemical systems through equivalent circuits (Fitting)
- Discover best practices for analyzing and presenting impedance spectra
- Understand both the potential and the limitations of the method
We will focus on delivering qualitative knowledge that supports intuitive understanding.
