      Just one request
      Your were talking about the increase of impedance over the period of time
      But didn't mention the cause
      It would be useful if you mention one or 2 of them

    It was a great introductory video! I had a few more questions to ask: 1) Is knowing the value of R the only purpose of performing EIS?
    2) What is the significance of the diameter of the semi-circle and its radius ("height")?
    3) Why do we apply just AC load to perform this experiment and not DC?
    4) Which parameter does the y-axis signify?

    • @AcrosstheNanoverse
      @AcrosstheNanoverse  4 года назад +3

      1. No, 2. Magnitude of “capacitance” - I put it in quotes because it depends on the system you are studying as to what that means exactly, 3. Look at the equations.. the phase shift between incoming and outgoing AC signal is important + we are using it to look at super fast processes. 4. Imaginary impedance.

I am a Master's student working on EIS of a li-ion battery for my thesis. It would be really helpful if you could share some references specific to EIS of a li-ion battery or another video going into more detail about this process.

      @AcrosstheNanoverse  4 года назад +1

      Thank you for watching! I’m not sure what you’re asking specifically, but you do typically need a potentiostat for performing electrochemical techniques like EIS. Gamry and Biologic are 2 companies that are known for selling these devices. Once you have one and know the theory behind how the technique works, you can do EIS! 😊

    Why charge transfer occur at only low frequency ?

    • @AcrosstheNanoverse
      @AcrosstheNanoverse  3 года назад

      At high frequency because it is a fast process. Electron exchange is very fast compared to other processes like diffusion.

    spectroscopy term is used for study of interaction of radiation with matter. So, in case of EIS,How is spectroscopy term is justified?

    • @AcrosstheNanoverse
      @AcrosstheNanoverse  3 года назад

      Good question! Spectroscopy is often associated with measurements of the light spectrum (or electromagnetic radiation spectrum); however, there are other spectra too! For EIS the spectrum that is being referred to is the spectrum of AC signal frequencies (Hz) that is being applied to/measured from the sample
