I feel like this is one of the big breakthroughs people have been looking for in electric manufacturing. Off the bat this is going to be sold at a costly markup but once production evens out then potentially it would become the norm for electric vehicles and at that point yes, but the question is now who wants to be part of that initial round of consumer product testers?

And if it does scale up would quite literally make fossle fuel power obsolite as wind solar has the potential to constantly power and store entergy.

Nah, the blocking issues for renewable / battery combinations isn't having a limited charge rate, it's having limited total capacity, and a high cost per kWh of capacity. Although if this allows a more rapid discharge rate it might help with handling peak loads, which would make the grid more efficient

No, it doesn't. No one wants a light duty truck that weighs 9000lb and needs to be recharged once an hour or thereabouts just so they can tow their work or travel trailer. It's going to be a while before EV's are the solution for all things transportation related.
The most important innovations are going to be weight and size reductions. EV batteries are fat pigs taking up a lot of space and adding tons of weight.
The F150 lightning weighs 600lb more than my similarly equipped truck, but can only go for an hour and a half with a trailer. That's just not an option when an ICE driveline will give you over 4 hours with that same load between refills.

Good thing everyday people dont need super duty road queens and just use small cars for transport. Just because its got little utility for one industry doesnt mean it wont solve a problem in another.

Yeah towing and hauling are going to be the last places that electric overtakes ICE's. But they'll likely get there eventually.
bigflamingtaco t1_is5naga wrote
I agree, it's just not going to happen by 2025 or even 2035. Most of the amazing improvements to batteries that get announced take at least a decade to put into use, when they don't come up against conflicts that prevent them from making it to market, like an inability to scale and bring the cost down.
We've also got some infrastructure woes that need to be resolved. The amount of throughput needed to have corner electric stations that can recharge vehicles like they fill gas tanks is insane, almost no cities have anything close to that kind of power capability, and we know infrastructure takes forever to get updated. Even if everyone were to sign contracts right now, there aren't enough works to make all the components and to install everything within a decade.
EV's are advancing at a great pace, but ICE is still going to be around for some time.

Yikes didn’t know it was that dramatic. Luckily battery tech will keep incrementally gaining. This is why a lot of people are way too (soon) optimistic. It’s the future yes. But we’ll play it like the internet. 1995 internet to 2022 internet wasn’t overnight . But I’m sure going from 2015-2035 will be similar for electric vehicles. Isn’t density increasing about 5% a year. It adds up. And I don’t know if that 5% is accurate. Up or down.
Anyways I didn’t know the hauling was that poor on the lightning. Maybe the big semi’s can make it work sooner?
Kelsenellenelvial t1_is3sdsc wrote
Yep, the energy density of batteries is a long way from hydrocarbons, where most of your reactant can be pulled from the atmosphere on demand. To some degree you save some weight on drivetrain and ICE, which can go into a bigger battery, but you get a lot better range increase by upsizing a gas tank than a battery.

Check out TFL's tests on YouTube. You aren't getting 3hrs of towing on the extended battery with anything but a small trailer. Their larger trailer cut it to 150 miles. If you're dragging a travel trailer through the wind, will probably see 100-120 miles.

I read a review by insideev's where they towed a campervan, that's where the number came from, that may be better aerodynamically though, apparently weight is not such an issue, but simply enclosing a trailer then would give enourmous range benefits
bigflamingtaco t1_iscttde wrote
If you can find that, I'd appreciate a link, didn't see anything on their website.
Geeky Schmidt towed a small Airstream camper, and it cut his range in half. Unfortunately, that's not the typical camper as those things are ridiculously expensive, and they also sit low to the ground, which limits where you can go with them.
I average 20mpg unloaded, 10mpg with a 7ft wide cargo trailer. Although I wouldn't tow a camper at 70mph like in the above situations, a typical hard side camper is 8-8.5ft wide and sits about two feet higher at the roof. At 60 mph, it's also going to cut the range in half, or worse, depending on the trailers actual dimensions and amount of junk attached to the exterior.
Camp-inn did an aero study of their teardrops and found their trailer that curves at the corner side walls in the front cuts through air better than the traditional teardrop style of cutting at the top and bottom. Probably has to do with how the air becomes turbulent exiting the sides of the vehicle's. Would like to see more mfg's try alternate designs for better aero, including stuff like lower skirts and those things the truckers put on the rear of their trailers.

A quick search shows a nice (non-ac) fiberglass buggy costs 7,000$ and a Standardbred race horse (whatever that means) is 3,000$. The harness is another 500$. So all in you're at 10,500$. The average new car price in the US is 47,000$. So it seems as though horse and buggy is still way cheaper than an automobile. I'm not sure that your example works well in this situation.
madd0cc t1_is7i3tp wrote
Sure you're right but what I meant is that while a car is still more expensive than horse and buggy, you still choose the car. You're paying for convenience or practicality of the times. Meaning you don't have to take care of a horse and you get more distance out of a car than a horse, etc. Also I'm sure the differential between a car and horse at that time period was way larger than it was today. Not to mention, you'd have to adjust for inflation, standards of living, etc. You can do the math but I'm not disagreeing that they should cost less.
I think electric cars should cost less than ICE car. There's way less parts but with raw materials market the way they are now, not sure what's going to happen. Almost all the manufacturers are supposed to release cheaper electric cars but they keep adjusting the price with the damn subsidies the gov provides which is plain f'd up.

It says that quicker charging will allow for smaller batteries. But I don't want to stop to charge my battery every 125 miles, even if it's quick. So...but quick charging is definitely good. I am under the impression, perhaps wrong, that battery life is related to the number of charging cycles which would defeat some of the saving from using a smaller battery.

Adding a nickel foil layer is inevitably going to increase the size and weight of a battery cell, so they're arguing that you don't need as many cells because charging more often is not as big of a deal if each charge is shorter.

I think what they are saying is that this specific system would be used on a vehicle with a smaller battery so the heat would be less of a factor. Maybe something like a delivery vehicle that makes short trips and might sit often. If you never intend on taking the vehicle on a long trip then the larger battery wouldn't be necessary and an unneeded cost.

pseudopad t1_is1d2j1 wrote
Super-fast charging is going to require some pretty beefy cables eventually. If you want to charge a 50 kWh battery in 10 minutes, you'll need something like 300 kW of power supply to that single charger. And that's if it's charging at constant power, which it likely won't, because it'll slow down towards the end. Serving 4 cars at once will require 1.2 megawatts. Not saying it's impossible, but it certainly requires some planning.

Their efforts are very much just a delaying tactic, though, as the economics have shifted decisively in favor of clean energy, with renewables now virtually all net new electricity generation worldwide and EVs projected to be a majority of the global car market by 2034 or even 2030.
Still, each year of delay is that much more cumulative emissions and warming, so pushing to accomplish the transition to clean energy sooner rather than later will still have tangible benefits.

I largely agree -- EVs started getting mainstream when batteries started getting cheap. No amount of online astroturfing is going to change the fact that EVs will be cheaper than ICEs in most major markets within a few years (source), or the fact that wind and especially solar are increasingly cheaper than fossil fuel power generation.
The economic forces propelling our transition to clean energy are almost inevitable at this point.
Their delaying tactics -- doomism and hopelessness -- are causing significant psychological distress to vast numbers of people, especially young people. As a result, even if their propaganda is not causing any delay in the energy transition it's still worth combatting for the mental health benefits alone.

I wonder if having a large supercapacitor as part of each public charger might allow for a feasible solution. The supercapacitor's charge time could be much longer than 10 minutes, but its high discharge rate could then allow for fast charging of a vehicle.
Not my field, so feel free to laugh if this is implausible. How large would a supercapacitor have to be to store 100 kWh?
edit: copied from below
100 kWh in 10 minutes would mean 600 kW supply per charger.
A standard house service provides 24 kW, so each charger would have to supply equivalent power to 25 houses. Let's assume a charging lot has 10 chargers - that's 250 houses equivalent in one small location (6 MW), corresponding to one 'gas' station.
A little searching seems to show the Tesla V3 charging locations have 8 stalls at 250 kW each, or 2 MW per location - and even these don't exist in most of the country. Sorry for trying to help.
edit2: That house equivalence is way off since groups of houses aren't pulling max load all the time. 6 MW should service much more than 250 houses. (600 homes per 1 MW is commonly cited, so ~3600 homes)

Maybe capacitors play a role some when, somewhere, but it's not required.
Right now a simple 250kW+ charger will have to slow down because of the car battery heating up....

The issue here isn't so much about kWh, but kW. Charge rate, i.e. time spent charging on a trip, seems to be a commonly cited operational obstacle causing so many to keep buying ICE vehicles. People don't want to have to charge for an hour or more every 200-300 miles.

You might be confusing combined theoretical peak loads with working demand loads in the real world.
Actual electric cars don't have 100 kWh packs, for starters. Most people are fine with half of that, 50kWh.
Also, very few people go to fast chargers with a 0% battery state. Most people also don't leave the fast charger with 100% battery state. In practice, it's more common to assume most drivers will charge 50% of the battery capacity, which for the sake of argument let's say is 25kWh.
Finally, the actual fast charge rate is proportionate to how close to empty the battery pack is.. a Tesla at 25% SOC topping up to 75% SOC might only start the charge at 100-150kW, tapering down below 50kW.
Yes, a very busy supercharging station in a dense city needs a fair bit of power (and may "peak shave" actual grid demand with on-site battery storage). For most cities however, it's actually not a huge load in practice, and easily implemented (which is why so many cities around the world have already installed them, even cities below 300,000 population like mine).

By Adrienne Berard
UNIVERSITY PARK, Pa. — A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today (Oct. 12) in the journal Nature.
“The need for smaller, faster-charging batteries is greater than ever,” said Chao-Yang Wang, the William E. Diefenderfer Professor of Mechanical Engineering at Penn State and lead author on the study. “There are simply not enough batteries and critical raw materials, especially those produced domestically, to meet anticipated demand.”
In August, California’s Air Resources Board passed an extensive plan to restrict and ultimately ban the sale of gasoline-powered cars within the state. By 2035, the largest auto market in the United States will effectively retire the internal combustion engine.

Good for them publishing their findings now, but I'd hardly call two year old science a "breakthrough" in the way this article suggests. If it were that transformative, a ton more cash would have been dumped into this over the last two years. Look at the funders - DOE, DOD and US Air Force. They're funding basic science research (which is not uncommon) in hopes of getting a breakthrough tech that can be commercialized and sold to the government. The breakthrough was years ago, scale is the challenge, and since it isn't scaled today I question whether it could be. Also, academic researchers are notoriously bad at commercializing their inventions, and government orgs are not in the business of commercializing tech. Maybe a third party manufacturer will swoop in and go for it.

I hate these articles. I work in the pharmaceutical industry and they remind me of the articles about some amazing cancer treatment that worked in a mouse. Until someone can reproducibly make a million of them at a competitive price, they don’t exist.

Hasn't it already been shown a number of times that fast charging of batteries is bad for the batteries in the long run? Unless there is new techniques or something that doesn't damage the battery in the long term that I have yet seen/heard about idk why people get so excited about fast charging all the time if your gonna have to replace the batteries much sooner.
Like maybe if it's an emergency and you need to charge your battery quickly to get to some appointment early or something than yeah. But seems like so many idiots want to fast charge their batteries ALL the time cause they don't want to sit around for an hour or so.

its becoming a non issue, your car will wear out before the battery will now.
GoblinKing22 t1_is38drq wrote
Is it still Lithium based? Because that's a long term issue as well. We need to get these new Aluminum Sulfur batteries up and running to really bring the cost down.

I saw one on here yesterday where they had it down to five minutes on an EV. Its kinda like coming out with a video for 30 minute abs when there’s already one for five minute abs.
GeniusEE t1_is3wgru wrote
This is complete nonsense as it relates to their improved battery: " it is now possible to build a 90 kWh electric vehicle (EV) pack with a 300-mile cruise range."
How on earth do these pass peer review?
Coolmikefromcanada t1_is3zayd wrote
does it speed the rate of damage
Jonherenow t1_is40nvz wrote
I don’t understand how it could charge faster. Isn’t the charge rate limited by the wattage of the charging station?
NasderTheFirst t1_is4fhig wrote
Keep in mind that faster charge means higher power and potentially more network cost. Still useful for long travels though.

Wider utilization of EV's require advancement in Battery tech. It isn't that EV motors are competing with the internal combustion engine, it's that batteries are competing with the stored energy in a conventional vehicles fuel tank. Similarly, broader utilization of current alternative energy sources requires the development of large format energy storage. Both technologies must advance simultaneously.

5EAM is involved in mining boron used in EV batteries because the company has a large deposit of the mineral, and it's a strategic resource for the production of electric vehicles.
Boron is a key ingredient in lithium-ion batteries, which are used in electric vehicles.

The faster a battery is charged though the greater the capacity loss over time. I am curious how that issue can be addressed.
40for60 t1_is5qk3k wrote
that isn't how it works, speed of charge is about resistance heat and keeping the battery and charger cool the number of times that you charge has been historical the issue with wearing out the batteries cathode but that is becoming less of a issue as cathodes are getting better.
snake_eyes21458 t1_isaepfj wrote
I think we are both saying the same thing, you are just getting more into the details. The faster chargers generate more heat which is what causes that loss in capacity. My statement was based on the SAE EV Engineering program which presented several studies showcasing number of cycles to 10% loss in capacity and when going from .5C to 1C the cycles went from 5000 to 200 cycles.
snake_eyes21458 t1_isafmmi wrote
After doing some more digging it looks like the study I mentioned used Nissan Leafs which don't have a robust thermal management system for their batteries (they are air cooled) so newer EVs probably perform much better.
40for60 t1_isaggkk wrote
right, the heat would be a issue if they weren't managing the thermals and since batteries are getting much bigger the cycles are going down so there is less strain on the cathodes along with cathodes just getting better. I think most batteries will far out last the suspensions and bodies of cars.

Electric vehicles are cool when you rent one, not buy them on your own. Because the cool factor drops when you have to replace a worn battery with a new one for... freaking $20'000. I don't remember, but replacing a fossil fuel tank doesn't cost an owner $20K, not even a 1% of that, and it doesn't wear in 5 or 10 years. It's a lifetime car part.

if you break a fueltank in an accident, most of the time it will spill out and nothing happens if there is not any firesource. if a battery is hit in an accident, how high are the chances, that the stored energy will instantly explode?
rwz t1_is45llr wrote
This is a super weird take. Punctured fuel tank is a huge fire/explosion risk, orders of magnitude more dangerous than punctured battery, that can catch fire slowly.
Battery is much larger, for sure, so it has more chances to get damaged, but overall flammable fuel is a bigger risk still.
S-Markt t1_is482gi wrote
its not weird at all. how often do you hear about exploded car tanks? nearly never. if a car starts to burn, it mostly happens at the engine.
a fuel tank can never explode or burn only by itself, it always needs a firesource while a battery can burn by itself simply from a shortcut.

>The researchers developed a new battery structure that adds an ultrathin nickel foil as the fourth component besides anode, electrolyte and cathode. Acting as a stimulus, the nickel foil self-regulates the battery’s temperature and reactivity which allows for 10-minute fast charging on just about any EV battery, Wang explained.
Increase in cell complexity means increase in processing cost. Does it scale?
