Lithium-Ion Batteries: Enabling a Greener Future

Brief talk on the how lithium-ion batteries work and their role in today's energy landscape
Exceptional presentation!
Hi thank you very much for tutorial, do you have zview, yet? with demo version only can graph 15 points is unsifficient. Regards Ambbar
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?
No room for miracles?
Likes indeed attract likes!
I'm 3/4ths of the way through looking for magnetic effects?
This video helped me in so many ways. I tried figuring out EIS for a while and this solved it so easily and quickly
how to calculate IR drop from GCD curve?
so it's like coulometry but AC and more sophisticated AC Green' s functions response
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?
lmao I'm either doing something extremely wrong or extremely right in life that this is what is recommended to me on my youtube home screen. Hey thanks for uploading though. I'm always down to learn even if some of this is slightly above my current level
Great video! I learned a lot! Thank you so much for posting this video!
the easiest and descriptive explanation of EIS🤩
hello, thank for video. Can you show me any ways for make plot voltage &x in LixPNb9O25?
Excellent!
Wonderful. It is veyr informative. Thank you for sharing this knowlege
thank you for your geat seminar
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.
Introduction to the most useless spectroscopy in the history of mankind.
😂😂 sure?
very good explanation......i am new to the field still i can get the things ......
a big big big love for u to upload this one !!! 😀☺☺☺☺☺☺☺☺
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)
You are amazing. You are gifted in teaching and you will be a great Professor if you choose to be one. Well done Elias!
hey, very well explained, bravo. Now I have to learn from your lectures. Well Done.
much thanks from CAS-china about your lectures
Very useful! Thank you very much for your explanation
Glad I found this. great job
Dear Elias, Thank you very much for your exceptional presentation on the EIS!!!
Thanks for the video, I have to do a Presentation on Mößbauer spectroscopy at Uni!
Which computing facilities you have used? And how much time it took?
We have a cluster associated with UCSB that we use for our calculations
Thank you for the nice explanation
Kindly , explain what each parameter means in EC and BT lab software
thanks so how to find all positions for lithium storage? could you share the technics , such as applying supercell software?
화학/화학공학과 전공 관련 강의 동영상이 제 RUclips 채널에 많이 있어요. 공부하는데 많은 도움이 되었으면 좋겠네요
Very enlightening lecture...... Thanks
Thank you ! Good video !
Thanks for sharing! Big help ^_^
Excellent explanation. Thanks.
doctor can you make video for explaining how to use EC lab software to test battery from beginning
You can watch vedio entitles, how to use EIS spectrum analyzer by Ayan sarkar, hope it work for you
thanks so much. I am much clear on eis now. have been struggling for four days
How to find R trapp
Which software is used for DFT?
At UCSB, the most common software for running DFT on structural energetics is VASP. With that said, there are many other codes that are better suited for other applications (i.e. calculation of NMR parameters on diamagnetic and paramagnetic systems are best accomplished with CASTEP and CRYSTAL, respectively).
@@eliassebti9253👍
@@eliassebti9253 I am also using DFT calculations for diffusion barrier calculations in Li-ion battery materials (in quantum espresso). May I know you linked in id/ google scholar profile to connect?
@@SantoshKumarBehara feel free to email me at esebti@ucsb.edu
@@eliassebti9253 have you heard of Wien2k? that's what my professor uses. He's primarily interested in spin dynamics, though we did use the software to study high-order harmonic generation. I'm still an undergrad so I only understand so much, but I worked with him over the summer so I got to learn a little bit.
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 (ruclips.net/video/_Vf_6Y8CcnU/видео.html) and NMR (ruclips.net/video/6KWY2zhNzsU/видео.html) in battery research. I hope these help you
thank you so much, that was very helpful
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
Excellent explanation thank you
Thank you for creating and posting!
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
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!
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?
