ABSTRACT

ABSTRACT: Electrochemical impedance spectroscopy is a measurement method for detailed investigations of electrochemical systems. The increasing number of recorded impedance spectra requires automated evaluations. Manual evaluations based on the visual comparisons of several impedance spectra in a Nyquist plot are subjective, time-consuming and thus no longer feasible. The challenge is to find quantitative, reproducible and therefore objective evaluation methods that coincide with visual impressions.
