Welcome to Electrochemical Impedance Spectroscopy – Theory, Measurement and Analysis


The course is a full-week course held in week 40.
Monday, Sepember 28th (7,4 hours):
Topic: General introduction to impedance spectroscopy.
Short description: This part of the course provides an introduction to concepts such as impedance elements, equivalent circuits, time-frequency domain relations, Fourier and Laplace transform and measurement methods. This part explains what creates impedance in electrochemical systems and how the impedance can be measured.
Lecturer: Søren and Samuel

Tuesday, Sepember 29th (7,4 hours):
Topic: Measurement optimization and Lab session
Short description: This part discusses possible sources of measurement errors and noise. Various methods for error minimization will be presented. Students will form groups of 3-4 persons where at least one person in the group have previous experience with impedance measurements and ideally have a running experiment/test setup. The groups will visit existing test setups, examine the impedance measurement conditions and discuss if there is anything that can be done to improve the impedance measurements.
Lecturer: Søren and Samuel

Wednesday, Sepember 30th (7,4 hours):
Topic: Impedance Modeling
Short description: The goal of the modeling is to get the most information out of the measured impedance spectra, with due respect to the measurement uncertainties. Various equivalent circuits will be examined and used to model the impedance spectra provided by the students. Modeling tools will be introduced such as ZsimpWin, Zview and Elchemea.
Lecturer: Søren and Samuel

Thursday, October 1st (7,4 hours):
Topic: Advanced electrochemistry, measurement and analysis methods
Short description: This part of the course provides an introduction to various advanced measurement methods such as 3-electrode setups, rotating disc measurements, higher harmonics, and systematic test variations. This part also present various advanced analysis methods such as DRT, ADIS and bulk fitting.
Lecturer: Søren and Samuel

Friday, October 2nd (7,4 hours):
Topic: Online diagnostics and trends
Short description: This part of the course discuss examples of online diagnostics of electrochemical devices and adaptive control thereof. The focus is on opportunities and challenges for further scientific and commercial applications of electrochemical impedance spectroscopy.
Lecturer: Søren and Samuel

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
