Exactly! Read this morning that Zinc/Air may be the next future battery! I didn't think those were rechargeable, but I guess new developments in chemistry allow them to be. No rare earths, no fire hazards.

Supposedly extremely high capacity so the fact it looses half its capacity every time you recharge doesn’t matter as much.
Yeah still a primary cell in my mind
I saw one of these live at a tv station in Dallas. A flywheel battery,
A giant high speed rotor/stator genset on a magnetic bearing in a vacuum.
Capable of enormous momentary loading.
I can only imagine an unconfined event as I could feel the thing shaking the room.

That's a sycon (synchronous condenser). They are often used at the termination points of HVDC links because that conversion (HVDC to AC) prevents there being any inertia in the link, so when you are moving a lot of juice over HVDC, having sycons there provides some inertia in the event of a trip or grid disturbance.
The Muskrat Falls HVDC link to Newfoundland has two large sycons where it terminates on the island for this reason.
The basic technology has been around for years, but wasn't terribly practical with the technology at the time.

San Francisco Municipal Railway (which is also a bus system) thought of trying it out a while ago.

They were supposedly just trolleybuses where they were hoping to be able to charge up the flywheel and travel short distances where there were no overhead lines. But modern trolleybuses have batteries and I've been on some that travel off the wires. In San Francisco they've got the 30 Stockton that goes all the way to the Presidio, where it has to travel about 3 miles off the lines.
No. And probably never unless superconductors are invented.
Another day another high pressure room temperature superconductor paper is retracted
No lk99 for you
Of course, we can move electrical power effectively without superconductors, although it would certainly be nice to move, say, 5000 amps, through a charge cable small enough to be plugged in by the average guy. The battery cell is always the limiting factor. There will have to be some serious changes to battery chemistry to take a full charge in say, 3 minutes.
With all these overlapping technologies and approaches, it just seems rather iffy’ to invest in an electric vehicle today. The spontaneous combustion thing is also a tad concerning.

In 200 years the world will have moved on to nuclear (fusion - not fission, though fission will have it's place). When it does, I'm going to tell everyone I told you so!
"the all new 2224 Blororp Traveler - range of 374 light years"
Just about the time they really get battery tech dialed in to the point where ICE can actually start being phased out - and I'm confident that they will within the next 2 decades - it'll be closer to obsolete than ever.

I was thinking that thermally speaking something in the battery is heating up rapidly on a quick charge, which is leading toward premature failure. If one wants to charge quickly reliably, finding a way to do that without generating more heat than the battery can quickly dissipate is going to be necessary, hence my superconductor reference.
You are correct but also for another reason, we don’t produce any electricity to replace petroleum. We don’t have enough in todays world with less than 2% EV penetration how would we even get to replacing 25% of the vehicles?
It won’t be batteries and if it is it will take 30 years to get to 25%
The public lives in a world void of reality and critical thinking, they react after the fact.
Sodium Ion battery charge rate is half that of LifePO4, for even slower refueling.
Anything regardless of the material being flammable or not is going to be a hazard if it has high energy density and shorted to ground, which can be done by damaging the battery still. It could be less likely, but I wouldn't take that as not having any form of fire hazard.
Sodium batteries have been the next big thing since like 2015.
If they do come out it will be like a buying brand new lithium battery in like 2005.
