NASA EIS Lithium Ion dataset: are phase measurments consistent?

Fiorentino Valerio Conte @Fiorentino-Valerio-Conte

03 March 2023 1 2K Report

We are analysing such dataset and it seems that such EIS measurements are not fully consistent. The phases are scattered and very limited in absolute value. The Magnitude values look a little better but still not satisfactory.

Has someone also investigated this dataset and would like to discuss shortly with me about it?

Notice about the frequency measurements : we try to distribute the frequency values in linear as well as in logarithmic mode. But the Nyquist or bode does not look consistent.

Suggestions? Opinions?

Surajit Sengupta

Yes. It is happening to me and resistance data is not consistent when I am using Biologic EIS equipment. The suggestion is to use Faraday Cage to avoid magnetic wave in the lab.
