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

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

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.

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.

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

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.

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

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

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.

…so still 10 years away 😂

Anthropologist here: some archaeologists suggest the ancient batter was used to apply metal plating to jewelry or other ornamental objects.

The 80% myth, you can only fast charge to 80%. However you can totally charge to 100%, it just has to be done slowly. (Strike 2)

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.

The only problem with the Bagdad Battery being any but an accidental battery is the copper had no external connection as it was originally made. To be a battery it has to have external connections for both + and -. Any experiments being done today modify the original Bagdad Battery design by adding an external connection for the copper bottle inside the device.

Sad to hear John is no longer with us. I remember reading and watching videos about his research, how determined he was.

Something not addressed: getting that much power into the battery quickly. Does it use DC, like L3 charging on Li-ion batteries today? Are we going to need 880A charging stations? What's the risk/effect on local grid?
OTOH, if they're reliable enough to be treated like giant capacitors, maybe we can just leave our cars plugged in to assist with power requirements during peak load times, and charge when the load is low, and get a credit from one's power management company.
OTO*O*H, I watched a conventional capacitor (that kept the clock in a timer "alive" even when unplugged,) lose its ability to hold a charge over a decade. How does the new tech hold up to hundreds of cycles?

I honestly hope we are "at that point" and EVERYTHING will shift to this better battery in a few years!

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.

I thought a barrier to solid state was cycle life. I haven't heard of anyone overcoming 300 -400 cycles.

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.
