1. Introduction

· What is impedance?

· What can we learn from impedance spectra?

· How to measure impedance spectra?

· How to analyze impedance spectra?

2. EIS: Impedance spectroscopy of electrochemical systems

· How to measure impedances of electrochemical systems?

3. Miscellaneous important issues:

· How to design cells for impedance measurements?

· How to build up models? How to fit model parameters to measured spectra?

· How to present data?

· What should impedance spectroscopy be used for?
