600 miles? Call me when they make one small enough to fit in a car
heyooooo
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 mean its a more a metric for the over vehicle. It can move its self that distance on a charge.
The battery would kWh but that alone is insufficient for evaluating the vehicle
kWh/Kg is really all that matters, maybe max charge/discharge rates too.
But they aren’t clickbatey enough for commercial news.
It’s what people care about.
An EV that can only travel 300 miles on a charge is a complete nonstarter for me. It’s simply not enough for trips I take with regularity.
But it it’s stupid because it doesn’t really relate to anything. Different cars have different ranges with different sized batteries and different efficiencies, at different weights and different volumes, so I have no idea what it means.
Wouldn’t it be both more straightforward and more meaningful to phrase it like: x% more power for the same weight as current LfPO used in Tesla standard range
Most importantly, batteries will always be expensive, so most manufacturers will prefer fewer/smaller for a cheaper and lighter car of similar range. Aside from trucks, I don’t see why we’d ever see many 600mile range EVs, especially if we get truly fast charging
How about the 2024 Ford Escape PHEV. 37 mile range on electric, which will cover most of dialy driving, and then it switches to gas. Should work out that you can pay 1/3 cost for fuel most percent of your driving, and not have to worry about long range trips. Base price is like 41k, meaning a used vehicle would drop quick.
Edit: apparently the 2025 now starts at 38k. So price came down didn’t find range.
How so, I’m curious? Do you drive into no mans land hundreds of miles away from civilization or are you a robot that never needs to take a break?
Even with a 10-15 mins recharge? A couple of times a year I do make a 500 mile journey and if there wasn’t a sea in the way I would happily do it all in one sitting. But as a teeny tiny compromise I wouldn’t mind stopping to charge once or twice along the way! It would add about 20 mins to the journey sure, but seems like it’s worth the benefits to me.
If it were any other company I would be thrilled. With Samsung, this is going to be internet enabled, you’ll need an app to turn your car on and off, and it’ll probably play ads at high volumes constantly while driving.
I know you jest, but Samsung is a massive battery supplier.
These will be plain old dumb batteries
I dunno man, my 21700 cells just got an OTA update and now my flashlights wont turn on without watching an ad blinked out in mores code first.
One could hope that the designs get leaked and the tech becomes widely available without the corporate shitbags.
I am 100% certain that Samsung is currently in litigation regarding exactly this kind of thing at this very moment. These companies have massive arms for corporate espionage and the like, and because of patent laws, it’s always worth spending time and money protecting your tech.
Are solid state batteries having issues with catching fire? I thought that was liquid batteries? Or is this just like saying everything bad that ever happened with lithium ion batteries will happen with everything else?
It was just a joke, ffs.
Samsung devices & appliances are notoriously prone to catastrophic failure - as a matter of fact, I actually had a Samsung TV melt itself - which turns out is a common issue (Google “Samsung tv melting corner”).
Then there’s the Samsung battery fire issues, Samsung refrigerator safety lawsuits, etc.
So what’s the catch? Is it the price?
Remember the Note 7 recalls?

For a smaller EV It would take around 200kWh worth of battery for a 600 mile range. The current Tesla “superchargers” put out 250kWh. So whatever is going to charge this battery will have to output roughly an order of magnitude more power in order to charge the battery in 6 minutes. That’s an impressive and scary amount of energy transfer.
Edit: I don’t know where I got 6 minutes from. So not quite 10X the power for charging, but a LOT more than current chargers.
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.
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.
Standardized interchangeable batteries would be neat. Pull into a battery station, a machine swaps out your packs and you’re on your way faster than a fill-up.
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.
20 years is very nice, how recyclable are they after that though?
The process for recycling solid state batteries is more complicated at the moment:
But really, who cares. Landfills are a negligible amount of land usage and land used for them can be repurposed after closing the landfill. As long as you bury it enough to keep it out of the biosphere the environmental impact of not recycling is negligible. Recycling is preferable for lowering resource extraction sure but as long as its still more resource efficient than a gas car that’s irrelevant.
To me this is the same as oil industry propaganda over wind turbine blades not being recyclable, like oh no it’ll occupy a few cubic yards of a landfill in 15 years, better build a new coal/gas plant instead.
