The Future of Lithium-Ion Batteries

Batteries power all of our modern electronics and increasingly our automobiles. What is in them? How do they work? What is keeping them from being better and how could they be made to hold more charge and last longer? This video explains all of that including some new exciting research in lithium-sulfur batteries at Illinois in conjunction with the company LYTEN. (Note: Car batteries have sulfuric acid in them, not hydrochloric -- I misspoke near the beginning of the video. Also, some internal combustion engines can last 300,000 miles, I just never have owned a car that long.)

I love how the Professor makes complex subjects (1) understandable and (2) fun & interesting. Fantastic work.

The legend is back when we needed him the most. Great to have you back with us professor. Love from India.

As a note: lead acid batteries have Sulfuric acid as the electrolyte, not Hydrochloric.

Thank you for making these videos. The general public knows so little about these technologies that we all interact with every day. This helps us understand these, which is important!

I always turn on the notification so I don't miss what the professor would enlighten us . *For Freeee*

I agree that IF a 3x or more battery tech could be commercialized it would change everything but I have seen so many companies promise that they were just about to do it only to never hear from them again over the last 20 years.

Revolutionary battery tech is always just a few years away. However getting out of the lab has been a stumbling block time and time again. I hope this time is different, but I'm quite skeptical.

I just wish my profesors were this engaging and briliant! As always, amazing video Prof. Ružic

[GearHeadLyfe]

Awesome a new video from my fav Prof! I'm all charged up! :)

main problems lithium sulfur battery: Lithium plus sulfur is a pretty decent bomb. This is in part a tautology, all batteries contain a lot of energy, but this one will explode 3x better than lithium ion batteries- in the event of a failure these batteries will melt through everythng like thermite, and stink of burning sulfur. 2) volume change. One of his electrodes, has to move through the separator. Unless the separator is movable, the battery will just well and go pop! Movable separators have all sorts of problems. 3) one of the electrodes is sulfur. An electrical insulator.

None of this is new, LiS batteries have been around for decades. An improvement in the separator isnt pointless, but it in no way makes these batteries viable.

I'm in the UK so woke up to this and left the notification there all day so I could watch when I got home.
Comfy pants on, bum in seat, cast to main TV, enjoy!

[Quakester]

Great to see you back was worried you had left this behind as it had been 7 months. Always great to learn new things and understand how they work.

[illinoisenergyprof]

The key is to be able to make graphene pure and cheaply. That is what Lyten is doing. It is very exciting to work on! How long to mass production? A few years perhaps? Lyten would have to comment on that directly. I am on the research end.

Professor "I've never had an internal combustion engine last more than me 300k miles." Me, laughs in Toyota Camry.

[iowaphotos]

Great to see you again sir love the explanation of different battery options. The continued research on this will be a big deal in the future. Never stop learning!

[Matt-dkwl]

Wasn't expecting the last 3 minutes there. That's pretty phenomenal technology!

[chasa]

Very nice explanation. Working in the petroleum industry for 30+ years and seeing it nearing the end over the next couple of decades, I enjoy seeing what the future might bring. I've taken baby steps, a 2017 Chevy Volt with 60, 000 miles, 50, 000 on EV and just purchased a 750-watt e-bike, great exercise and a viable commuter.

[gabrielskater]

Thank you so much for these expansive and very well explained videos! No one else like you making this content on the internet, Professor!

[munashedov]

I would have appreciated a bit more coverage of how solid these new batteries are, as in, how close to being mass produced. Are they just in the concept phase, a few working prototypes, or just around the corner from initial production runs? (Also having the references in the video matched in the description as actual links would be nice)
