Dear Elias, Thank you very much for your exceptional presentation on the EIS!!!
Thank you so much for this lecture on EIS. It was a very thoughtful, well-organized talk and I am heavily benefitted from this tutorial. I am so thankful. All the best wishes for your research
You are amazing. You are gifted in teaching and you will be a great Professor if you choose to be one. Well done Elias!
Really find a great 👍 video to learn eis never had such a organised and detailed video on this topic
Thanks you so much for your efforts. I really appreciate it.
This video helped me in so many ways. I tried figuring out EIS for a while and this solved it so easily and quickly
Thank you for creating and posting!
Great video! I learned a lot! Thank you so much for posting this video!
Very useful! Thank you very much for your explanation
Excellent explanation. Thanks.
hey, very well explained, bravo. Now I have to learn from your lectures. Well Done.
Very enlightening lecture......
Thanks
much thanks from CAS-china about your lectures
Excellent explanation thank you
Wonderful. It is veyr informative. Thank you for sharing this knowlege
thank you so much, that was very helpful
a big big big love for u to upload this one !!!
😀☺☺☺☺☺☺☺☺
Exceptional presentation!
Thank you for the nice explanation
the easiest and descriptive explanation of EIS🤩
very good explanation......i am new to the field still i can get the things ......
thank you for your geat seminar
thanks so much. I am much clear on eis now. have been struggling for four days
How to find R trapp
I would like to learn more from you about NMR and XPS if you would like to make more videos! So excellent!
Hi Sally! Thank you so much; I'm glad you learned. I have videos on XPS (czcams.com/video/_Vf_6Y8CcnU/video.html) and NMR (czcams.com/video/6KWY2zhNzsU/video.html) in battery research. I hope these help you
Thanks for sharing! Big help ^_^
Hi Good content, Have a question: you explained how to correlate the 2 semi circles with SEI and positive electrode, but can you explain what is the linear correlation at very low frequencyies (what is warburg impedence referring to)
Excellent Lecture ...... Thank you so much. I am also working in the field of Energy Storage Devices and Materials.
Me too
Can u be of some help regarding data interpretation?
Hi, can you please tell me if we want to do EIS for a battery at ocp, do we also need to use a reference electrode?
Thank you a lot professor
Just a lowly grad student here, but I'm happy to see this is useful!
@@eliassebti9253 Hi Elias, thanks for your well-explained videos, could you explain how can separator prevent the transport of electrons? At around 38'. I'm curious is because the pore size should allow for Li to pass through but why no electron? Is that because the separator itself is non-conductive?
@@sallyju9999 Hi Sally, the blocking electrode you are referring to is made of polyethylene glycol which has extremely poor electronic conductivity. It does, however, allow for the conduction of Li ions through complexation/decomplexation of Li-ions and ethylene oxide (EO) structures (onlinelibrary.wiley.com/doi/full/10.1002/advs.202100736). The pore size is not the reason for conduction.
Thank you so much!
Thanks a lot professor.
Have you any ohter video pour spectroscopy impedance complex (SIC)?
Just a graduate student here! Sorry no videos on the topic :( Good luck
how to calculate IR drop from GCD curve?
I'm 3/4ths of the way through looking for magnetic effects?
Hi thank you very much for tutorial, do you have zview, yet? with demo version only can graph 15 points is unsifficient.
Regards

Hi Ambbar, I have used ZView and EC-Lab but both are licensed softwares. I can recommend impedance.py as well, a free python package for EIS analysis. There are functions for converting inputs from many different company EIS file formats (I.e. .z, .mpt, etc…)
hi, im having trouble finding this
quote from the shapes of impedance A.R west et al. Adv. Master. 2. 1990 No 3, can anyone pls help me?
so it's like coulometry but AC and more sophisticated
AC Green' s functions response
