Samsung delivers 600-mile solid-state EV battery as it teases 9-minute charging and 20-year lifespan tech

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

One could hope that the designs get leaked and the tech becomes widely available without the corporate shitbags.

Wait, which company had their battery blowing up ? And were not safe for flight. If these battery blew up then it would be devastating.

...then it will catch fire.

…and will probably explode.

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.

Remember the Note 7 recalls?

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.

EE here. Chargers put out power in units of kW, while batteries store energy in units of kWh or MJ or what have you. Otherwise, you're absolutely correct.

Typically Distributed Generation (DG) scale solar PV and battery storage sites are sized anywhere from 1 to 10 MW.

At 1 MW, you could run (1) charger at a speed of 1 MW, or (2) at 500 kW, etc. Usually need just (1) transformer for that size installation too.

At 10 MW, you can run each charger at 1 MW or so, but you're also talking about probably (4-10) transformers @ $250k USD a pop. Installation prices go up the more you demand in power transfer.

Then you need to consider that most DG projects need to pay for the upgrades to their downstream grid architecture, meaning reconducting or upsizing cable, breakers, switches, transformers, reactors, sensors, relays, etc.

Not saying it's impossible. You could co-locate and DC-couple solar PV or Wind parks next to charging points to get around some of the grid upgrades, but most people live in areas that require homes and grocery stores and other buildings than flat land meant for solar PV or Wind.

When it comes down to it, it's so much easier to just trickle charge your EV at night via arbitrage and when you're sleeping so all of this infrastructure doesn't have to been upgraded - and I'd argue upgraded needlessly because we need to save that copper and iron and materials for upgrades to the parts of the grid meant to interconnect renewables.

But there is no silver bullet to these things so we'll likely see more, larger chargers come through unless regulators stop it from happening.

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

Who cares that’s ages away /s

There are companies that claim to be ready to recycle most car batteries, but there are just not many old ones yet

Things which oxidized.

Seriously I hate articles like this.

Unfortunately the source does not seem to indicate what Samsung is using.

https://www.thelec.kr/news/articleView.html?idxno=29222

It does say that LG will be producing a sulfide based electrolyte.

Also, what is a "solid state" battery anyway? A capacitor?

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

Thankfully solid state batteries save 30-50% weight compared to current ones so batteries can be a bit smaller than they otherwise would be. This one will likely be 150 kWh.

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.

Yes

TL;DR: Depends on what you mean.

Long version:

Disclaimer: I’m not an expert by any means, I haven’t vetted the links properly (or at all), they’re mostly there for illustration and if you want to read further. Also, the last time I actually read up on this is quite some years ago, so stuff may have changed in the industry and/or my memory on specifics is foggy. Many of the links lead to Tesla sources since I first looked into this topic back before Musk made it known to the public that he’s an insufferable human being.

Batteries are usually structurally integrated into the chassis with modern EVs, since that means space (and often small weight) savings, and is easier/faster to do in manufacturing.

With that knowledge, it is safe to assume that replacing a car’s battery is a difficult or next to impossible task, outside of end-of-life reuse.

But this is actually where it gets interesting, since EV batteries last many years anyways: What happens when the car’s time has come?

Well… the batteries can be reused. It’s not a trivial process, there’s several ways to do it, but the best intuitive explanation I’ve found is this: In raw ore, lithium and other metals are present at maybe 0.1 or 1%, per tonne of material. In batteries, it’s maybe 99% of reusable, expensive material. Even if you let it be 90 due to inefficiencies in recovery, or whatever, it’ll still make way more sense financially to work with old batteries – once you have the process figured out and automated machinery to get it done in place.

All that is assuming total destruction of the existing cells, which, depending on their state, may not even be necessary at all. In fact, it looks like all of that may not be needed for as much as >80% of batteries. Wow!

And we all know the best way to ensure companies are doing something is if the financial aspect aligns with their goals. It’s in their best self-interest to be able to and actually do this.

So: Replaceability per car – eh, doesn’t look to great. Replaceability across the industry? Perfect.

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.

Not to worry, there's lots of other parts they can cheap out on.

Battery replacement after ten years is for very old EVs shrub much shorter range. The old model Nissan Leaf is what makes these stories. More recent cars have already outlasted the usage that the old pretty bad ones had by a significant amount. Your criticism is like saying you don't want a mobile phone because the buttons are so fiddly.

Huh

solid-state battery

They can't do what you describe.

Solid state has zero possibility of doing either of those. That is one of the big selling points. The others are that they are 30-50% get, they last longer, and they can charge faster.

from what i understand, most vehicles use LiFe (i think this was wrong actually, i think most modern EVs use li-ion batts, they really should be using LiFe though.) battery technology, which is almost innert compared to LiPo technology, phones use Li ion batteries which are different from both of those.

Lithium batt technology sucks.
