NASA Achieves milestone Solid State Battery

I think many people miss that energy density means no matter what we use, the more energy stored the greater the danger in an accident.

Fast "refueling" has always been the best method, with vehicles able to maintain about a weeks worth of range. As it stands if people can get 2-3 days worth from a vehicle it's just acceptable - but whatever is used, hot-swap fuel (such as filling a tank, replacing a cell or swapping your batteries) is going to be important.

At least lithium batteries charge really fast (especially when they're running flat) so quick chargers are a thing and a reminder that being 100% full doesnt matter - get 30% filled while you're shopping and who cares past that?
 
I would certainly use just over 200m/320km the entire working week, I believe most people don't differ much from that.

I don't understand the obsession with 1000m autonomy, it seems that suddenly everyone works in another state or is a taxi driver. To be honest, I would rather have the entire country connected by high-speed trains than drive or take a plane. It would be much less tiring.

Towing? Cold outside? Running the heater or AC? Been used for a few years? Particularly windy? All these significantly reduce range. That 320 km range can very easily become less than 150 in poor conditions. Suddenly having your car at less than fully charged in that scenario gives you clipped wings.
 
I don't understand the obsession with 1000m autonomy
It's a bad faith strawman generally brought up by those who have been raised to worship the internal combustion engine. Never mind that most of them never leave the city they live in; and if they do it's via train or plane. The handful of people who actually need to regularly travel hundreds of kilometers can stick with hydrocarbon-powered vehicles that allow them to do so, and the rest of us can switch to EVs and stop polluting the planet.

That is a common misconception. Chemistry matters. Sodium-Ion for example, will not act like napalm when exposed to the air, nor does it easily catch fire. Lithium does both of those, ridiculously easily.

I don't understand the obsession with 1000m autonomy
1000miles is silly, currently. But it is a nice goal to shoot for.

It's a bad faith strawman generally brought up by those who have been raised to worship the internal combustion engine.
However, 500miles isn't silly or a strawman argument. I current get a bit better than that with two of my vehicles. One is a Honda the other an Acura, both are 4cylinder and I generally get right around 500 miles per tank, more if I've been on the motorway a lot. EV can't currently come close to either the range or performance of those two vehicles. And until EV can match or exceed that range on a per-charge basis, it is not good enough. Full stop.
 
I'm talking about Norway not your country. So here emission is zero. Obviously, if you have your electricity from burning coal then the electricity you charge your car with, has already produced CO2.
safer does not mean safe but rather safer. You are talking about reading your post and yet you did not read mine :)
most of the batteries in cars are Lithium-Ion. I don't know a car that does not utilize lithium-ion in commercial use today. Tesla and Mercedes for instance.
Closing them up is the problem you know since they burn with extremely high temperatures. Especially if you are on a ferry.
About the O molecule, all batteries have it but some, may have less of it. All commercial cars use either LCO (Lithium cobalt Oxide) or NCA (Lithium Nickle Cobalt Oxide). Still burns as hell if you put fire to it. Still closing them up is a problem.


That thing has way less power than Lithium-ion batteries and thus burn less rapidly but also have way less capacity and dont hold the charge well.
I doubt car makers would have used it in a car. These types of batteries are inefficient for a car traction battery. These have been replacing Ni-Cd(cadmium) batteries since cadmium is very harmful to human lungs when inhaling it.


Are safer. Still use lithium still respond poorly to high temperatures and mostly cost a lot to produce. Not saying this direction is bad but as of today, everyone is using lithium-ion and it is not going to change tomorrow. So the prospect of using solid state batteries in cars is promising but we're not there yet and considering the complexity of the solid state batteries, we still have long way to go.
1st paragraph
Well, even Norway does not have 100% electricity from renewable sources. How? Check here: https://energifaktanorge.no/en/norsk-energiforsyning/kraftproduksjon/

Most of the EV are Li-ion, but not the same is true for hybrids. Which is why, most of the hybrids are safer - when you talk about their batteries. :cool:

If the Li-ion burns, it is indifferent if it is ferry or asphalt. As the heat & temperature would burn through both. :cool:
Only thing is, ferries are backed & very good insulated. So if 1 thing starts burning, most of those will end up burning. ;)

Not all batteries have Oxides, like example S-Sb (SSB) or Ni-MH batteries. So those can burn, but not by themselves. :cool:

2nd paragraph
Well if you think that charge burns, then you are greatly mistaken. Ni-MH burns less, as it is:
  1. not so volatile with elements like Li
  2. does not have Oxigen inside tu burn
Also, Ni-MH does hold a charge. You can't discharge it like Li-ions batteries (for extreme accelerations) & they don't have the power-to-weight ratio. But Ni-MH is several times more safer in a car, then Li-ion. So all our (my wifes & mine) cars have both Ni-MH batteries. The lesson I have learned from working in EV car industry.

3rd paragraph
Are they safer? Sulphur is the number one element used in gunpowder. :cool:
Are they cheaper? Sulfur & Selenium are not so much abundant elements. :cool:


50 cents more: still waiting to get Na based batteries into production, which can be get from natural sources without polluting environment (like from a sea). :cool:

I think many people miss that energy density means no matter what we use, the more energy stored the greater the danger in an accident.

Fast "refueling" has always been the best method, with vehicles able to maintain about a weeks worth of range. As it stands if people can get 2-3 days worth from a vehicle it's just acceptable - but whatever is used, hot-swap fuel (such as filling a tank, replacing a cell or swapping your batteries) is going to be important.

At least lithium batteries charge really fast (especially when they're running flat) so quick chargers are a thing and a reminder that being 100% full doesnt matter - get 30% filled while you're shopping and who cares past that?
1st paragraph: Well, not exactly. As charge does not influence the fire, only the energy it can release.
So, think of it this way: charged battery compared to discharged is like using a same gun, only one is with real bullets (charged) while other bullets are gas filled (discharged). They both fire, only difference is in the "volatility".

3rd paragraph: Yes, you can. But using them too frequently on charging port of ~30% charging will bring your total amount of charging down.
& you do not have unlimited times of charging on batteries... :cool:

I would certainly use just over 200m/320km the entire working week, I believe most people don't differ much from that.

I don't understand the obsession with 1000m autonomy, it seems that suddenly everyone works in another state or is a taxi driver. To be honest, I would rather have the entire country connected by high-speed trains than drive or take a plane. It would be much less tiring.
1000km is a silly argument from "diesel influenced drivers".

Any car needs to have 400km range on normal gas of tank. So everything more is an extra. :cool:

That is a common misconception. Chemistry matters. Sodium-Ion for example, will not act like napalm when exposed to the air, nor does it easily catch fire. Lithium does both of those, ridiculously easily.
Well, not exactly. Sodium will react with air & can burn. But it needs more energy to start burning, especially compared to Lithium.

But if we get out the Oxides from battery cells, we might stop the fires when they actually catch on one. :cool:
 
Sodium will react with air & can burn.
While true about sodium generally, Sodium-Ion batteries, as formulated, do not burn easily.

Your opinion is not a fact.
It's not wrong either. EV's need to compete with ICV's to be acceptable as a replacement.

EDIT:
Just watched a video, that while not directly about the NASA SSB, it's somewhat related to what we've been talking about.

Very interesting this!

Well, it is not my opinion, but "an industry standard". Which is why, petrol cars were made (in general) to be used with (standard engines) to have at least 400km range. Which became as a 700~800km range, when same car was made with diesel engine. And is the same 400km range, that people talk about, when they talk about "EV cars" - like on topic SSB one.

I happen to be working in car industry. Do you?

While true about sodium generally, Sodium-Ion batteries, as formulated, do not burn easily.
It depends, what is in that "-ion" part. So if there are some Sulphur, Phosphorus, Oxides or similar reactive element - yes, they would burn. Not as easily as Li, but once ignited they would burn.

Look at it this way: kerosine & diesel have lower volatility & higher flashing point then gasoline. But drop a plane from a sky & it will ignite. :cool:

Well, most of the mining to get the materials for the batteries isn't done in the most environmentally friendly way. And if you're recharging on coal/gas power, still polluting. It is what it is, we like things that are made possibly by energy, and usually there is pollution to varying degrees to get that energy.
Just read about the Congo and cobalt for LI-ON and other batteries.......scary stuff. Maybe solid state batteries might be a game changer???

Any car needs to have 400km range on normal gas of tank. So everything more is an extra. :cool:
Uh, just gunna say that 99% of aussie cars won't achieve even 400K
They might in biased tests on flat highways for the entire tank, but in city driving they wont.

These things vary a lot between countries, but the USA does have a trend towards large and wasteful. Probably because some parts of the country do indeed have giant flat spaces of nothing between state lines, and others just had vehicle envy and needed something as big and 'manly' as their neighbours.

Anyone who thinks this tech isn't improving steadily hasn't paid attention, Li-Ion to Lifepo4 was a massive change, yet people think all lithium batteries are the same. I keep seeing "HURR FIRE RISK HURRR" anytime lithium is mentioned like gasoline isn't flammable.

Lithium batteries need to be compared to a gasoline vehicles fuel tank - because it is the fuel tank now. Neither one should be punctured or set on fire.

Having a 120AH Lifepo4 battery for camping here now, i've got more first hand experience with how utterly different the technology is - the main issues come from peoples demand for super fast charging to top up when not at home. Slower at-home rates with cheap electricity have no heat issues and no danger.


My view is they need to standardize optional generators for these vehicles - put a standardized space in the trunk dedicated to them (with ventilation and a high current connector) and let people run what they want or need to keep their vehicle going. Be it gasoline, Diesel, hydrogen - it doesn't matter. It's a top up device and not powering your drivetrain, and being swappable means it's not tying the vehicle down to any one technology and would allow smaller, cheaper batteries in the first place. I ran a hybrid LPG/Petrol car for a decade, and it's no different to that IMO - 90% of the time I ran off LPG, and then I'd use the petrol only when that tank ran out because I couldn't get a refill wherever i was.

Lithium Sulphur Iodide solid state batteries, more energy dense and fixes their longevity issues.
 
Let's talk some basic math, and understand what truly matters here. I can do a simple stack, and show you why hydrocarbons are amazing.
Current Li-ion : 200-300 Wh/kg
2040 projected Li-ion: 750 Wh/kg
Maximum chemistry limitations of Li-ion: 1250 Wh/kg
Basic hydrocarbon: 12000 Wh/kg

Hydrocarbons are easy to fill, and you can go from 0% to 100% of a tank in minutes. There's risk of combustion...but exposure to oxygen is not inherently risky. There's no limit to the amount of mileage a tank of hydrocarbons produce...and maintenance is relatively easy with most components that need replacing being non-rare earths...unlike the average motor that uses a ton of rare earths. Toyota is pushing for hydrogen because it's an inherent middle ground between battery and hydrocarbon. Honestly, I agree that it's better...assuming you can make the fuel not constantly leak. EVs are not a permanent solution, and anyone who believes they are is obviously not accounting for replacing batteries, the environmental impact of rare earth mineral extraction, or the inherent trade-off between needing less mass to offset lower energy densities to have the same range. Materials science, including solid state batteries, is great. That said, it's trying to find a science answer to a basic math problem.
 
Honestly, I agree that it's better...assuming you can make the fuel not constantly leak.
It's not better, it has the worst of all worlds: lower energy density than hydrocarbons, far more expensive and dangerous to store, inherent losses, the list goes on...

EVs are not a permanent solution
This nonsense again.

and anyone who believes they are is obviously not accounting for replacing batteries
We are.

the environmental impact of rare earth mineral extraction
As opposed to the environmental impact of global warming?

or the inherent trade-off between needing less mass to offset lower energy densities to have the same range
Fallacy of believing that range of EVs needs to be the same as ICEs.

Materials science, including solid state batteries, is great. That said, it's trying to find a science answer to a basic math problem.
Same fallacy as above.

Current Li-ion is actually more like 600 Wh/kg.

Besides, internal combustion maxes out at around 50% efficiency, but modern cars are more like 20-40%, so that's more like 2400/4800 Wh/kg.

Furthermore, there's really not much left to research and improve with ICE cars, whereas battery technology improves every year.

You guys are really willing to drink the Green Kool-aid, aren't you.

1) Hydrogen, as I stated, has a storage issue. You claim that the energy density is lowest...based on what exactly? The storage medium is not set, therefor your claims are remarkably ignorant. STP hydrogen is extremely low energy density...but that's a hugely stupid assertion.
2) EVs are stupid. Period. You name me the company that's recycling the batteries, and I'll name you a company that's deep into governmental incentive programs. Don't believe me, then go ahead and try. I'll wait, but not hold my breath.

3) Let's just look at the price of EV battery replacement. Not the Musk BS, but the real cost. 13k USD. Cool. You replace them at about 70% capacity...so let's just give you a 10 year lifespan. What's the cost of a new engine and transmission for a regular ICE engine? Let's assume high at about 3,400 for the transmission...or about 6k for the transmission and engine. That's for a BMW...so about half the cost. Cool.... Let's also do the math on that lithium recycling instead of a basic steel and aluminum recycle...wow. It's great that this is a "better" solution. It's better in the same way that an EV is better in the snow...or heat...or really any inclement weather.
4) You...are...an...idiot...if...you...think...ICE...is...worse...for...the...environment....overall. I said it slow, so you can let it sink in. If you don't get it, let me explain it. Neodymium, copper, and gold. Rare earths that are insanely difficult to remove from the earth, primarily harvested in China. To be fair, ICE uses platinum in the catalytic converter...in quantities so small that it's a joke. Once you combine most energy being generated from hydrocarbon sources, you suddenly see that ICE is evil...but less evil than EV. Excuse me, but the "feel good" math required to make EV look awesome is also the admission you are incapable of critical thinking. Period.

5) You are reading words into what I say that aren't there. This is called a strawman...I figure that I have to explain this because you're either acting in bad faith or not thinking. I'd like to assume bad faith, as it's not assuming ignorance. Now, lower energy density requires lower weights to create the same range...you're making up an argument. My wording was that decreased energy density was a problem... If you want to assume that lower ranges are fine then you've had golf carts for decades. Buy one of those, and stop talking. I assume my vehicle's range because travel is required. There are already people who use electric vehicles exclusively, and have been doing so for decades. If you want an example go to Florida, and see one of the golf course communities. No car, but an electric golf cart, and everything is fine. In the adult world, where travel is expected, having to stop every 4-5 hours for multiple hours is what we like to call burning money.
6) On the other side of 5, trucks. The semi kind. Where is the Tesla semi in use? That's where the extensive charging network is. Cool. It's a bunch of opportunity...unless you're a trucker. Note that the average trucker is bound to an amount of hours...so pulling to the side and charging something is burning money. It's expected they can drive for hours without stopping...and it's why extended volume tanks exist. Still, you want to make a strawman that "electric doesn't have to have the range of ICE..." and all I can ask is how you expect OTR trucking to function with an EV replacement.

7) "It's a fallacy" is a great argument against your strawman. Against what I said, this is baby putting both fingers in their ears and screaming they can't hear me. EVs are a great patch for people who want government to make things affordable, or for those who are within the limited window of viability for their use. Florida is living proof that it's fine...and I even think there's a city in Georgia that does the same. That said, it's not a solution. It's a crutch. Crutches are fine...unless you actually want to solve the issue. Thing is, you don't need to believe me. Our very left leaning higher learning institutions are already highlighting this...so it's not about politics. It's about reality. Read here: Harvard article about Rare Earth Extraction

______________

1) Current Li-ion, in labs, is that high. Not so much everyday sources. That's, in fact, 269 Wh/kg: Tesla Battery Article
2) It's great you want to bring up efficiency. Let me do the real math. Hydrocarbon burned, to heat steam to supercritical temperature, to turn turbine. Most of heat vented to outside world...turbine has efficiency. Power is converted...which is about 98% efficient. Power is sent along lines...which vary wildly in efficiency. Power is received and transformed, again losing efficiency. It then feeds into a charger, that loses efficiency, which charges a battery, that loses efficiency, which then feeds into a motor that loses efficiency. Note the hydrocarbons most often used to create electricity are still part of the chain...you are just ignorant of the efficiency. The counter is energy is used to pump fuel, fuel is used to transport fuel, an ICE engine combusts fuel, and a transmission converts linear pressure into circular movement at an inefficiency. You failed to do all the math, and thus failed to answer why EVs are more feel good than do good.

3) ICE tech is literally evolving at the same speed as batteries. Cylinder idling, ammonium burning, hydrogen burning, and a litany of other tech is out there. Battery tech is evolving incrementally as component are improved with materials science. Note that 1250 Wh/kg is a calcuable maximum value. It's because the chemistry, something as old as Ancient Egypt, is an easy electrochemical potential. You want to claim ICE is dead end...well maybe you should do a little more research.
4) Your efficiency is stupid. Don't misread...I'm actually making an argument for you. NASA - engine efficiency ICE engines are up to 37% efficient (diesel), and EVs are (assuming our mostly hydrocarbon based current electrical infrastructure) 27%. This is why I note all of that stuff in point 2...and the funny thing is that more energy dense batteries don't fix this...and NASA never covered losses due to weather...and a litany of other things. Neither EVs nor ICE are greatly efficient...but 37% of 12000>>27% of 600. Simplistic math.


______________

You both seem to want to pretend that nothing is easier than EVs. Could I ask you how that's going in a country that basically mandated them, and produced them in enough volume. Specifically China. Insufficient charging infrastructure, so people fight over chargers. Insufficient safety...so cars regularly combust. Cheap price due to subsidies, so you've got more people pulling more power. Just search the term "happy grandpa" and see what a truly EV based solution is.
Me, I'm banking on less stupid feel-good. Amonia, hydrogen, and a few other ICE technologies are the future. They aren't an expensive band-aid to make the rich stupid people feel better, or a governmental program away from viability. This is the same reason I believe ethanol is stupid, bio-diesel is another stepping-stone technology towards a real solution, and the way forward for tech is higher efficiency and lower power, instead of a bigger and more dangerous battery. The literal only exception is if these solid state batteries can perform as promised at affordable levels...in which case we have another better stepping stone...and that's it.

I'll be glad to hear the next whining about how "global warming" is something you're fighting with this. It's extracting rare earths...so it's causing plenty of polution. If your argument is EVs, and by extension the batteries that power them, are better than ICE while primarily powered by burning hydrocarbons then you're just silly. Now if we were all near a nuclear reactor, hydroelectric dam, or some other renewable that wasn't rare earth intensive I'd eat crow...but even NASA's paper above conveniently stated (without calculating transmission losses) that an EV powered this way would reach 40-70% efficient...without citing how they came to that conclusion.
My idea of fighting climate change isn't feel good...I want nuclear. I want sustainable wind and solar. Unfortunately people are squeamish about nuclear and most of wind/solar is either from China or not viable in most locations. Life's a beach...maybe it's time we learn to swim with the nuclear sharks instead of remaining "safe" on the beach where parasitic worms in the sand enter the soles of our feet. Yeah, that's a pained metaphor...but no less painful than the wail of tree-huggers who cannot fathom reality beyond the apparent "goodness" of their message. There's a reason the guy who founded Green Peace left and disavowed them. Biznews article on Patrick Moore


Let me also state a few things.
1) If high speed rail existed in the US, I'd choose it.
2) If I could get away without using a car, I'd be happy.
3) If Green Energy could supply the power we needed I'd embrace the up-charge.
4) If you ignore anything that isn't in your line of sight Green Energy tech is great...but I'm not an idiot.
5) Increasing battery energy density is great. You should be the first to strap a moltov cocktail to your pants. Me, I like not having a bomb in my pocket.
6) If electric didn't suck so bad, or if I didn't live in a temperature range between 0-100 F, I'd see the value in an EV. As it stands, I see them as large golf carts for the rich. They are not beholden to me on how they spend their money, but if they start trying to shame me I'll call them out on their hypocrisy. Like I've done above. Funny that. You are the one who picked a fight...maybe instead of pretending there's no counter-point you can educate yourselves, and come to the table with a real argument instead of a useless dismissal and feel good propaganda. From one engineer in manufacturing, to you, I suggest that feeling good is stupid unless you're actually doing good.
 
This thread is about solid state batteries. It's not an EV versus ICE debate.

Please heed that when posting, especially if taking the time to post a long discussion.

Solid state batteries, please.

Power is received and transformed, again losing efficiency. It then feeds into a charger, that loses efficiency, which charges a battery, that loses efficiency, which then feeds into a motor that loses efficiency. Note the hydrocarbons most often used to create electricity are still part of the chain...you are just ignorant of the efficiency. The counter is energy is used to pump fuel, fuel is used to transport fuel, an ICE engine combusts fuel, and a transmission converts linear pressure into circular movement at an inefficiency. You failed to do all the math, and thus failed to answer why EVs are more feel good than do good.

3) ICE tech is literally evolving at the same speed as batteries. Cylinder idling, ammonium burning, hydrogen burning, and a litany of other tech is out there. Battery tech is evolving incrementally as component are improved with materials science. Note that 1250 Wh/kg is a calcuable maximum value. It's because the chemistry, something as old as Ancient Egypt, is an easy electrochemical potential. You want to claim ICE is dead end...well maybe you should do a little more research.
4) Your efficiency is stupid. Don't misread...I'm actually making an argument for you. NASA - engine efficiency ICE engines are up to 37% efficient (diesel), and EVs are (assuming our mostly hydrocarbon based current electrical infrastructure) 27%. This is why I note all of that stuff in point 2...and the funny thing is that more energy dense batteries don't fix this...and NASA never covered losses due to weather...and a litany of other things. Neither EVs nor ICE are greatly efficient...but 37% of 12000>>27% of 600. Simplistic math.


______________

You both seem to want to pretend that nothing is easier than EVs. Could I ask you how that's going in a country that basically mandated them, and produced them in enough volume. Specifically China. Insufficient charging infrastructure, so people fight over chargers. Insufficient safety...so cars regularly combust. Cheap price due to subsidies, so you've got more people pulling more power. Just search the term "happy grandpa" and see what a truly EV based solution is.
Me, I'm banking on less stupid feel-good. Amonia, hydrogen, and a few other ICE technologies are the future. They aren't an expensive band-aid to make the rich stupid people feel better, or a governmental program away from viability. This is the same reason I believe ethanol is stupid, bio-diesel is another stepping-stone technology towards a real solution, and the way forward for tech is higher efficiency and lower power, instead of a bigger and more dangerous battery. The literal only exception is if these solid state batteries can perform as promised at affordable levels...in which case we have another better stepping stone...and that's it.

I'll be glad to hear the next whining about how "global warming" is something you're fighting with this. It's extracting rare earths...so it's causing plenty of polution. If your argument is EVs, and by extension the batteries that power them, are better than ICE while primarily powered by burning hydrocarbons then you're just silly. Now if we were all near a nuclear reactor, hydroelectric dam, or some other renewable that wasn't rare earth intensive I'd eat crow...but even NASA's paper above conveniently stated (without calculating transmission losses) that an EV powered this way would reach 40-70% efficient...without citing how they came to that conclusion.
My idea of fighting climate change isn't feel good...I want nuclear. I want sustainable wind and solar. Unfortunately people are squeamish about nuclear and most of wind/solar is either from China or not viable in most locations. Life's a beach...maybe it's time we learn to swim with the nuclear sharks instead of remaining "safe" on the beach where parasitic worms in the sand enter the soles of our feet. Yeah, that's a pained metaphor...but no less painful than the wail of tree-huggers who cannot fathom reality beyond the apparent "goodness" of their message. There's a reason the guy who founded Green Peace left and disavowed them. Biznews article on Patrick Moore


Let me also state a few things.
1) If high speed rail existed in the US, I'd choose it.
2) If I could get away without using a car, I'd be happy.
3) If Green Energy could supply the power we needed I'd embrace the up-charge.
4) If you ignore anything that isn't in your line of sight Green Energy tech is great...but I'm not an idiot.
5) Increasing battery energy density is great. You should be the first to strap a moltov cocktail to your pants. Me, I like not having a bomb in my pocket.
6) If electric didn't suck so bad, or if I didn't live in a temperature range between 0-100 F, I'd see the value in an EV. As it stands, I see them as large golf carts for the rich. They are not beholden to me on how they spend their money, but if they start trying to shame me I'll call them out on their hypocrisy. Like I've done above. Funny that. You are the one who picked a fight...maybe instead of pretending there's no counter-point you can educate yourselves, and come to the table with a real argument instead of a useless dismissal and feel good propaganda. From one engineer in manufacturing, to you, I suggest that feeling good is stupid unless you're actually doing good.
If you're done with the essay, let's get back on topic, thanks. Feel free to start your own thread that is ICE vs EV.

You're making a lot of arguments based on "current" tech that's in the field. What's in labs and what is yet to be discovered is another story. Most of the factories for building the batteries that will power the next generation of actual mass market EV haven't even been designed yet, let alone built. So unless you also have the skill of predicting the future, let's avoid speculation and "simple math" when we don't have the actual figures.

On a simplistic note, nuclear powered electricity going to clean solid state batteries is going to be better for the environment than any combination of burning hydrocarbons, regardless of the efficiency.

The people ridiculing the first gasoline powered cars and lauding the perks of horses made many similar logical arguments, yet here we are, enjoying streets free of horse dung.

So...let's talk for a minute.

What is the point of a battery?
Where is it used?
What is the primary motivator?

The point of bringing up ICE was energy density...and if you read the attached article it's focused on that. Most of what we would need increased energy density for is...movement technology. Talking about energy density improvement in a vacuum is great...it's how articles like this get started and gain huge traction. Note that NASA's goal here is to power landers and rovers...which are EVs...
I'll do you one better though. How long has this been going on? 14 years of this at least: Toyota in 2010....

It's hard to have technology inextricably linked to something...and then pretend that it can be removed. But fine. Let's forget about the reason that energy density is a huge focus...and the industry that is driving it forward.



You want to talk about lab technologies...it's been 14 year. There are people who weren't born when this started being talked about...who now are in their teens. I want to talk other sources of power...and how they are practical...because this is a freaking joke. Let's get our clown shoes and make-up out...'cause Bozo's always want to pretend to be genius.
How so?
1990 - Sony - Li-ion at 100 Wh/kg
2010 - Commercial cells - 200 Wh/kg
2024 - Tesla - Li-ion at 269 Wh/kg

34 years to, very charitably, triple energy density. When your competing technologies are literally magnitudes of order better than your lab grown non-production announcement then we've got a problem.

If you'd like to be but hurt about "what will happen in the future" then please explain this to me. 34 years. 200% (actually 169%) more capacity. At that rate the practically available tech will be at the 1250 Wh/kg by oh wow...231 years. Praise be...in 2221 we'll finally have technology that is great after the death of our children's children's children.

Oh, but lab technology is 600 Wh/kg... So we're clear, that's not an argument. What that is, is the admission that infinite money and no scalability can produce results... So...are you going to provide the infinite money? NASA's budget is complained to be small...but they throw around millions of dollars regularly.



You want a TL;DR? Fine.
At current rate of production tech development you will be able to compete with its mathematical maximum energy storage medium in 200 more years. Hope you invest in cryogenic storage. You can't even argue it's a power function instead of linear...because that's easy to map out. Also, when your primary sources are Toyota, NASA, and Tesla it's hard to not see battery, and know it's for exactly one thing...

Those who have a goldfish's memory might not see the pattern here...but if you're an adult in age, then you should know this is a repeating story. Even ARS has identified this in a graph...tech is linear, but cost is a power function...and it's why today seems so bright...not because the tech is evolving in leaps and bounds. It's because manufacturing is making it cheaper to have the tech: ARS - Li battery tech





Please note that that final dig is stupid and shows your extreme ignorance. The sterling engine was around and causing issues before ICE...and you started this off-topic. People had issues with it because it was hugely expensive and performed worse than a horse, just like your current Lithium ion tech. Your battery tech started in ancient Egypt. Canopic jars and a lead-acid solution. If you want a strawman, congratulations. I won't say more...because you tend to not want critical thought...but if batteries are thousands of years old...

I'm not interested in arguing with you. Post about solid state batteries and their development or take it somewhere else.

You're entitled to your own opinion, share it in the appropriate place with people who want to engage.
