Solid-state batteries - The science, potential and challenges

Interested in learning more?
Here are some books which I recommend to learn more about the history of batteries and how they've impacted the world

Solid-state lithium-metal batteries have the potential to be more energy dense, safer and faster charging than traditional lithium-ion batteries but what is the science behind them, potential of the technology and challenges.

Here in this video we'll cover how solid-state lithium-metal batteries work, the different configurations/materials and reflect on practical considerations towards understanding how feasible the technology actually is.

Your video is by far the best on the fundamental physics of SSB

[linkedinroger]

With no discernible academic capability...I somehow manage to the gist of what you show and tell Billy. Thanks! 👏

[sharmila]

Prof. this is one of the enlightening lectures. Thanks a lot. I would ask if you could make a presentation on actual lab fabrication along with Dos and Don't and any calculations precautions etc that would be more helpful for graduate students... In case you have links of those practical demo of Battery fabrication and testing you could share here... Thank once again...

[phamgiangson]

Thank you Prof. Wu. Have followed you recently. It is thorough and easy to comprehend

[dillipkumarmishra]

Prof. Wu, thanks for sharing. Very well made and extremely informative.

[AlsoDave]

Your videos are always really informative and engaging thanks. Just, is it possible to increase the volume in the audio mixing please, you're much more softly spoken than the website seems to expect!

[gleambrite]

Great video. We seem to have the energy density and chemical engineering down. The biggest issues seem to be the pesky anodes. If you made a battery pack you could replace anodes like we do oil filters. Thank you for showing the differences between cell and pack. I do think we could improve on the issues with battery packs. Catode could be 70% of a solid state battery. Easy manufacturing. Replacement of anode and maybe even electrolyte. Make one big 3 part pack for EV, s.

Thank you very much - a very informative and well done summary. Lithium anodes would require significantly more lithium than current lithium-ion batteries. Lithium shortages are already predicted in scenarios for 2030 and 2040. Therefore, this ASSB type is the most critical for me. Maybe solid state sodium batteries would be a solution.

ACCORDING TO MY RESEARCH I noticed that in electrochemistry it is the migration of bonds which is at stake rather than that of ions, this is where the secret of the solid electrolyte lies

[zamba]

Hello Dr. Quite some elaborate explanation on the subject, so much appreciated. Just one question, could you clariffy on the mechanism for the movement of ions in an all solid state battery? That wasn't clear to me considering how this hapens in a liquid electrolyte. Other reading materials on all solid state batteries will also be so much appreicated, thanks once again. Zamba

[deshaganisathish]

Prof Billy, thank you for sharing, nice video. It is very useful.

[Janamejaya.Channegowda]

Thank you for sharing, greatly appreciated.

[change_of_game_energy]

Very fine video Billy!
I have worked more on making energy that goes into the batteries

[tatchkult]

Very informative presentation Billy
So what BTRL stage for ssb is in right now? I’m View from Weeks hall if you remember 😄😄

[lizzyventura]

Dr. Wu's videos on basic batteries and this last one are very interesting, the way he explains it is very didactic and instructive, thank you for sharing it. Which is to invite you to my country to implement an experimental solid battery manufacturing plant that you know about and expose in your videos. We have all the raw materials available for manufacturing such as lithium in solid state, graphite and anthracite mineral carbon, Manganese, cobalt, aluminum, copper, nickel, cadmium, and other rare earths and aluminas that could be used in its manufacturing, reducing transportation costs. and time. Peru is the second largest producer of copper in the world and a mining country par excellence with all the mineral resources to give it added value that needs to further develop its industry in different economic and energy generation areas. My cordial greetings and I hope that you study the proposal and gather investors in development technologies to invest in Peru, South America, in all types of scientific and technological projects.

Hey, I would like to use this as a source for my research paper, is it possible I use this as a citation?

[doobiescoobie]

Why dont they make fleet vehicles that have swappable batteries? If they did, when new technology replaced lithium it would be a quick swap for battery vehicles without replacing the body of the vehicle.

[davidvennel]

This was great, I learned a lot. Thanks Prof. Wu!

[breakhart]

I always wonder are solid-state battery a battery or a super-capacitor? 🤔

[eriknordqvist]

I have already seen factories in China that manufacture Solid-State batteries.
