  • Course 1: Electrochemical Impedance Spectroscopy (EIS) – Fundamentals and Principles

    Wednesday, September 6, 2017 | 10:00 a.m. EDT USA

    Electrochemical Impedance Spectroscopy (EIS) will be described from a theoretical point of view. Various representations (Nyquist, Bode, etc.) of impedance data will be introduced. Guidelines on how to interpret the data will also be provided.

    This webinar will focus on the following key topics:

    • Definition of impedance
    • Various representations
    • Impedance interpretation: the deductive and the inductive way

    A PDF copy of the presentation will be sent to all attendees after the event.

  • Course 2: EIS at Higher Frequencies for Battery Studies – Good or Bad Indicators for SoC and SoH?

    Wednesday, September 20, 2017 | 10:00 a.m. EDT USA

    Impedance data at higher frequencies can be used, to some extent, as indicators of the State of Charge (SoC) or State of Health (SoH) of the battery. A discussion of the relevance of this indicator, as well as the most accurate way to determine this value, will be discussed.

    This webinar will focus on the following key topics:

    • Typical shape of an impedance graph on a battery
    • How can it be used for battery monitoring, optimization, and sorting ?
    • Various ways to measure this value and our recommendation

    A PDF copy of the presentation will be sent to all attendees after the event.

  • Course 3: Lower Frequency Impedance Measurements – What Information Can we Get on a Battery?

    Wednesday, October 04, 2017 | 10:00 a.m. EDT USA

    In batteries involving intercalation of species, by using the impedance response at lower frequencies, it is possible to extract the diffusion coefficient of the intercalated species and monitor its change during discharge and charge.

    Low frequency impedance can also be used to estimate the capacity of a battery. Several strategies are given to perform reliable measurements.

    This webinar will focus on the following key topics:

    • Impedance data at lower frequencies that can be used to extract diffusion parameters of intercalated species
    • Several possibilities that are available, depending on the type of impedance graph obtained

    A PDF copy of the presentation will be sent to all attendees after the event.

  • Course 4: Factors Affecting EIS Measurements – How to Check and Correct

    Wednesday, October 18, 2017 | 10:00 a.m. EDT USA

    When performing an impedance measurement, it is necessary to ensure that the modulation is low enough such that the behavior of the system is linear. It should also be confirmed that the system does not vary in time, and that its stationary state is reached. Several strategies are given to check and correct these phenomena.

    This webinar will focus on the following key topics:

    • For reliable EIS measurements, it should be checked that the response of the system is linear, time-invariant and stationary
    • Several strategies are presented to perform reliable impedance measurements

    A PDF copy of the presentation will be sent to all attendees after the event.
