Chemical processes, their equivalent circuits and common pitfalls

Further elaboration on the equivalent circuits for EIS measurements and how they are linked to the chemical processes. Johan also explained some of the pitfalls of using equivalent circuits to model the impedance response, as it is always possible to construct an equivalent circuit with the right output characteristics, but that might not be a …

General electrochemistry, equivalent circuit models and measurement techniques

Presentations on general electrochemistry such as electrode-electrolyte interfaces and basic electrochemical relations including the Nernst equations and the Butler-Volmer equation. Explaination of the background for equivalent circuit models and how the impedance response looks for these circuits in a Nyquist plot. To give a better understanding of EIS measurements a practical example is shown.  General …
