Electrochemical Impedance Spectroscopy (EIS) in the Range 1000 Hz to 0.1 Hz
Presentation of the spectrum of different purchasable cells and technologies. Evaluation via modelling and modell parameters. Interpretation by means of application relevant values. Specifics while determining the spectrum, Nyquist Plot, especially dependencies of temperature and SOC. Aptitude of the method 1) for single cell application, 2) for series application with limitation in time.
