It could help deal with the Tesla problem. Which in the words of Jeremy Clarkson are “a bit burn-ey”.

With the typical electric car being powered by a lithium-ion battery, why would I want to drive around waiting for the battery to play detonate like a bad cell phone of laptop battery?
Los Angeles to Seattle on a single charge, anyone?

Going over the passes at the speed limit will be a challenge to say the least ... don’t even think of it in the winter ...
“As compared to lithium-ion, it is still limited on charge rate,”
Aye, there’s the rub.
I see the real problem being the ability to deliver X kW/h, at home, overnight. I was able to recharge a 26kWh battery from a standard 110V outlet between getting home and leaving for work; dropping that to 4 hours required installing a 220V line. The 200kWh battery mentioned (top-end Tesla) would take 40 hours to fully charge with the latter source; that’s mitigated by most drivers rarely depleting the battery completely, and likely having sufficient time between long (>300mile) drives to top it off.
All that said: “As compared to lithium-ion, it is still limited on charge rate” is a serious problem. The aforementioned Li-Ion rates are acceptable in practice, but taking any longer quickly becomes a problem for users. You have to, on average, be able to recharge faster than normal use depletes power.
And however a well-funded supercharger works, it _must_ reach 80% charge within 30 minutes. Any longer, and nobody will want to use the charger; they’re using such a station for compelling reason.
Always glad to hear about new battery tech.
Never hear anything about it afterwards.
In the long term, plan for cross country drive. You pull over for food for 30 minutes or more and the charge if fully charged for another 300 miles.
You regularly sit on 20 gallons of gasoline without concern. What are you worrying about Li-Ion for?
Dang that Thermodynamics Law!
We must get that repealed, pronto!...............
Exactly my point. 30 minutes for an 80% charge is fine. Take any longer than that, I’m gonna get ticked off pretty quick. (Or more like my wife is going to get really upset about cumulative delays beyond already-annoying food & potty breaks.)
Li-ion tech is functioning pretty comfortably within thermodynamics laws.
However, it’s still close enough to the limit that any other tech that takes longer is just plain unacceptable.
they used to recommend stop every 2 hours for a snack and rest room and stretch. i used to go 4-5 or until I almost ran out of gas.
They just need a steady supply of element 115.
“You regularly sit on 20 gallons of gasoline without concern. What are you worrying about Li-Ion for?”
But that Gasoline does not randomly explode and catch fire.
The car that randomly exploded and caught fire in front of me at rush hour on a 10-lane freeway (one direction) seemed to.
Oh, and that repair truck that burst into flames as I walked past, the driver puzzled why it stopped running.
And then there’s “carbecues” mentioned on the morning traffic report several times a month.
Almost forgot: there was the time I brought my car in for repairs, and the repair guy commented “I don’t see this problem often - usually the car just burns up first.”
again?
Indy 500 is a rather specialized use, calling for specialized tools. You don’t drive an Indy car to the grocery store.
If you really do want to race electrics, there’s the Formula E.
