Battery 4.0: The Solid State Battery Revolution

Solid state batteries are just around the corner with most major battery and car manufacturers pursuing this technology. What does the future of battery production look like?

To be fair: Toyota has published a "2-3 years to market" article since about 2014. I'm not saying they won't get there, but just that it's very hard to know if they're actually making any progress at all.

[jsalsman]

A good friend works at a battery lab where they have several solid-state projects underway. She's very optimistic for the long term but questions the three year mass production timetable as a little too aggressive for what they're seeing.

[adilsongoliveira]

I can't help but to chuckle a bit every time I hear the name of Mr. Goodenough who, IMHO, should be called Excelentasheck :)

[charlesnathansmith]

"The Solid State Battery": "Cool!"
"The Baghdad Battery": "Ohhh noo..."

[JustATakit]

I didn't know that John Bannister Goodenough passed away I was really hoping he would live to see the way solid state batteries improved our lives. He never settled on being good enough always searching for perfection Thank you J.B.G. you'll be missed and always remembered.

I am in a rare age bracket in my mid 50s. Old enough to remember the days before the Internet and common rechargeable batteries, before cell phones and way before smartphones. But still young enough to expect to see the revolution that solid state batteries will bring. I get to see it all.

"Who shall we task with inventing a completely new type of battery that will change humanity forever?"
"Well, I guess John B. Goodenough"

[rayoflight]

The cost of a solid state Li-ion battery prototype is still prohibitive; because all the sintering and machining of the separator, requiring flatness at molecular level. Ions have a problem diffusing in solids but there isn't a single word on how that is achieved; but the most likely process utilised for the separator is the same doping method used in the production of semiconductors.
My impression is that the year 2025+ is an hope and not a certainty.
Thank you Prof. Miles

1:45 I'm sorry but for me you're losing credibility here, the Baghdad Battery is widely known to most likely be only a myth and what is sure is that of all people archaeologists reject the hypothesis that it was a battery

[diGritz]

I have an old (early 50's) Transatlantic Radio. The battery is rechargeable
weighs in at a bit over 6lbs. and can output 9v or 90v. It's a dry zinc-carbon
pile and it still holds a charge. Not exactly state of the art but then
I doubt anything made today will hold a charge after 70+ years.

Any article that starts with the 'Baghdad Battery' touted as the first ever battery is likely poorly researched overall and not worth watching further. The idea that the 'Baghdad Battery' was _actually_ a battery, or some form of electroplating apparatus, is overwhelmingly rejected by archaeologists.

[rtfazeberdee]

EVs aren't limited to 80% charge, its just that after 80% state of charge the speed of charge drops off a cliff and its not worth staying. Most bladders fail before the charge in the battery empties

[oleksiyprotas]

You're getting it wrong about 80%
- For slow charging it's the default charging target because staying for a long time at high SoC makes the battery degrade relatively faster, so there's an incentive to slow charge to 100% only it you really need it (not applicable to LFP and some other types of battery)
- For fast charge the safe charging power is gradually reduced as the SoC grows and then at one point transitions from CC to CV saturation charge phase where the current naturally is rapidly falling even if there was no safety limit in place. You can absolutely charge to 100% on a fast charger, it's just that the tail % usually take so much longer it's not worth it. Yet there's no damage in doing so.

The Baghdad battery is not a battery. It was a jar for prayers. Btw jar has now been lost, thanks to our war in Iraq. 1:12. Ref Miniminuteman channel.

This is actually super exciting, especially in combination with the upcoming solid state cooling. I'm imagining laptops, handheld PC's, and other small form factor devices that have not only cooling potential that is much greater, quieter, and smaller, but also lasts days at a time on a single charge while only taking 10-30minutes to fully charge. The future of hardware technology is definitely bright.

[Powermongur]

I remember many years ago Toyota told me I could buy their Solid State Battery car in 2022. Every time i went back to their website the launch year just increased.

[pixelpunchyt]

don't care, no amount of battery innovation will replace my desire for a roaring dino-powered V12 with 5 mpg

[dylanlasky]

John B Goodenough has had so much impact on modern technology in very varied fields it's crazy

[vitasartemiev]

The Baghdad battery is not a battery. Every credible archaeologist agrees on this. If you are going as far as dedicating an entire video segment to it, the least you could do is to not spread decades-old bogus claims.

[marsrocket]

I’ve been hearing about solid state batteries being the next big thing for years now. It’s not worth reporting on until they’re actually close to production.
