You joke but I literally pictured a super long battery for a solid bit before it clicked. I was thinking maybe it was coiled and technically really long like a spool of wire

It’s such a dumb metric for batteries. I wish people would stop using it.

I know you jest, but Samsung is a massive battery supplier.

These will be plain old dumb batteries

Its a battery that'll be used by other manufacturers

…and will probably explode.

A couple things: solid state batteries weigh much less. Solid state batteries are 30-50% lighter per kWh. The initial ones will probably be closer to 30% lighter. A 100 kWh battery weighs about 1400 lbs (635 kg). Shaving off 400 lbs is pretty significant and results in much better range for the same battery capacity. The battery pack is likely closer to 150 kWh.

Second thing would be the charge rate. Yes, a supercharger can 250 kW output (not kWh BTW) but a few factors means that they often do not. First thing would be heat. If the charging cable or the battery gets too hot, the the rate slows down. The next thing would be the fact that current batteries have to start at a slow rate and end at a slow rate. Solid state batteries do not have those issue nearly as much and can more consistently hit that 250 kW output for a longer period of time.

This thing, they are likely using 350+ kW chargers. Higher than 350 kW is pretty rare but the odd 400 kW and 450 kW charger does exist.

And doing some more digging, I found that it is from 8% to 80% in 9 minutes. And even then, it does not say it is the same 150 kWh battery that is being charged that fast. This could be marketing crap where it is giving numbers for a ~85 kWh battery to compare it to EVs today. An Ioniq 5 takes about twice as long to go from 10-80% at 350 kW.

The current Tesla "superchargers" put out 250kWh

kW

My wall outlet charger puts out 250 kWh, if you leave it in for 2 weeks straight...

So each supercharger will need it's own miniature fusion power plant. Great, now fast charging solid state batteries will always be 30 years away.

Yes, Teslas can charge at 250 kW, but they do not sustain that charging rate for long. As the battery charges, its charging rate drops. If newer battery technologies can sustain the higher charge rates longer, they could theoretically store more charge in less time.

This is the big reason why solid state batteries aren't an EV miracle. Pack density and charging speeds these days are already limited by cooling capacity. Trying to pump a few MW of power into a battery pack to get 600 miles in 9 minutes is going to melt the car, or require lugging around a huge cooling system.

FTA:

Apparently, they are also rather expensive to produce, since it warns that they will first go into the "super premium" EV segment of luxury electric cars that can cover more than 600 miles on a charge.

So yes. Expensive initially.

Basically, yes. The big issue with solid state batteries is figuring out how to mass produce them at a price where someone will actually buy them.

The process for recycling solid state batteries is more complicated at the moment:

Today's EV's batteries will already outlast the car.

Not this one. It’s 600 miles long

I like this comment, because Samsung in other areas does indeed get confused about batteries being consumable.

I mean, the headline does say 20 years soooo...

Also, Teslas are approaching 10 years old and as far as I know their batteries are still going strong (yes, I know their quality control is otherwise sketchy). The Nissan Leaf batteries are getting pretty sketchy, but they don't have any battery conditioning - just air-cooled. That's not doing longevity any favors. All other major EVs have battery management systems and seem to be holding up ok. They're also generally warranted for 8 years. I don't think they'd only have a 2-year buffer between warranty and expected life.
