EIS Workshop 2025
Over the past two days, the GS-EES hosted the EIS Workshop 2025 – a focused, practice-oriented training on Electrochemical Impedance Spectroscopy (EIS) with the instructors Sandro Haug and Thomas Zubiks from Metrohm Deutschland.
The workshop provided participants with:
💡 A solid foundation in the physical origins of impedance, and the principles behind EIS measurements.
💡 Training on hardware and software implementation – giving insight into the measurement setup, as well as hands-on experience with conductivity measurements of battery electrolytes and determination of the MacMullin number.
💡 Guidance in modelling electrochemical systems using equivalent circuits, routines for data fitting and evaluation, and best practices for analysis and presentation of impedance spectra.
💡 A balanced view of both the potentials and limitations of EIS – highlighting that while EIS is a powerful tool for battery research, careful execution and critical interpretation are essential.
We were pleased to welcome researchers from all our partner institutions Karlsruhe Institute of Technology (KIT), Ulm University and Justus Liebig University Giessen – coming together in Ulm for improving and sharing their knowlegde and skills in EIS.
