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)

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 (kzfaq.info/get/bejne/lbyWkpmKnanHnok.html) and NMR (kzfaq.info/get/bejne/bLGHjJWrzbTeo4k.html) in battery research. I hope these help you

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?

@@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?

@eliassebti9253 2 жыл бұрын

@@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.

Hi thank you very much for tutorial, do you have zview, yet? with demo version only can graph 15 points is unsifficient. Regards Ambbar

@eliassebti9253 5 ай бұрын

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…)
