In February, Dr. Nicolas Murer, a leading expert in Electrochemical Impedance Spectroscopy (EIS) will present a series of webinars, in conjunction with PlugVolt. These presentations will help users working in both fields of applied and fundamental battery research optimize their EIS experiments by obtaining high-quality measurements as well as monitoring battery resistance parameters as a function of State of Health (SoH) and State of Charge (SoC).

The first webinar will explain which techniques to use and when. Dr. Murer will cover key themes in this training module such as GEIS (current-controlled EIS) and PEIS (potential-controlled EIS) techniques, describing their relative advantages and disadvantages as well as explaining how to optimize EIS measurements by choosing the right measurement technique for your experiment.

Another key theme covered by the webinar is the importance of linearity and stationarity of a system in EIS experiments. Dr. Murer will present key tools such as quality indicators, and demonstrate their value in the webinar.

The second webinar will cover indicators that accurately reflect the  SoC and SoH of a battery as a single cell or in packs. Battery parameters related to resistance are excellent candidates for such indicators. AC and DC methods can be used to determine resistance. The DC method is fast and simple, but it gives a composite parameter, whereas the AC method is more advanced and gives complete parameters. After giving examples of data on single cells, we will present three-electrode, battery packs, and modules measurements.

This webinar will focus on the following key topics:

Obtaining battery parameters via DC and AC methods
• The pros and cons of each method
• How these parameters can be used to indicate SoC and SoH
• Data examples
• Three-electrode single cell and measurements on battery pack or module
