Thank you very much and God bless you.

The battery retained 76 percent capacity after 500 consecutive six-minute charging cycles.
Charging an electric vehicle fast without degrading the battery has been one of the harder problems in battery research. A team at Adelaide University says it has a way through it.
Six minutes. That is how long it took their new battery cell to reach 85 percent charge, while delivering an energy density of 240.4 watt-hours per kilogram.
The result comes from a team led by Professor Shi-Zhang Qiao, an ARC Industry Laureate Fellow in the University’s School of Chemical Engineering, working alongside researchers from Imperial College London.
Why fast charging has been hard to crack The issue with existing high-capacity batteries, silicon-anode and lithium-anode types, is that speed comes at a cost. Capacity fades quickly, and fast charging generates heat that accelerates that degradation and raises safety concerns.
“Current models also increase heat generation during fast charging, which can exacerbate battery degradation and safety risks,” Professor Qiao said. “Until now, achieving more than 90 per cent charge within 10 minutes without sacrificing energy density and cycle life has been a formidable challenge.”
Standard approaches involve reworking the electrolyte — the medium ions travel through inside the cell. But changes to the electrolyte affect the whole system and tend to compromise ionic conductivity elsewhere.
What this approach does instead Rather than modifying the electrolyte throughout, Qiao’s team targeted only the electrode surface. The method uses sulfur vacancies as catalytic sites that attract specific anions to the battery interface during charging, promoting the formation of a compact, lithium fluoride-rich protective layer (the solid electrolyte interphase) with fast lithium-ion transport pathways built into it.
“The catalytic sites on the electrode surface attract anions to the battery interface and promote the formation of a robust inorganic protective layer, which is critical for fast charging and long-term stability,” Professor Qiao said. “Unlike traditional electrolyte engineering, which often affects the entire electrolyte system, this strategy regulates reactions only at the interface, allowing fast charging without sacrificing ionic conductivity.”
The silicon anode achieved an average coulombic efficiency — how much charge put in can be drawn back out — of approximately 99.94 percent. At 10 minutes, the cells reached 91.4 percent.
How it held up over time After 500 consecutive six-minute charge cycles, the cells retained around 76 percent of their original capacity.
“Our test cell exhibited excellent performance, achieving about 76 percent capacity retention after 500, six-minute cycles,” Professor Qiao said in a press release. “The cells also exhibited excellent stability at 10 minutes of charging. The discovery could help enable electric vehicles that charge in minutes without sacrificing battery life or energy density.”
The team’s next step is scaling the technology and testing it under real operating conditions. Their findings are published in Nature Energy.

LOL, I never saw that episode...
NO ONE WANTS EVs
We got lots of them around here!...................
Electric Golf Carts have been working just fine for decades and decades.
You are in/near The Villages?
Let’s hope that toxic batteries are not the future... Our environment can’t handle it... Nor should it. We are destroying our planet to appease the followers of Al Gore’s tainted religion of global warming. In short order there will be tens of millions of toxic EV batteries littering our planet and the mess they make will be enormous. Add to that the completely useless plastic EV hulks that will be littering our waste dumps and that will not be a pretty site.
Hybrid’s do make sense... And they are more sensible vision for our future.
No, but my daughter is................
I’m in the panhandle, Destin/ft. Walton, under Alabama.............
You are wrong. That’s comparison is as A FUEL, not motive force.
But a car has to have MORE than fuel- it has to have motor, transmission, etc, which are heavy. Most of the energy in gasoline is lost to heat in the motor/tramission/braking, etc. Batteries are heavy, but so is a motor, transmission, etc.
So, 230-300k hrs/kg battery in an EV is better than a gasoline car - why? Because with a 4500 lb EV vehicle, you can drive 600 miles (more on how this is possible later). Right now, the range of a 4500 lb EV is only about 350 miles With a gasoline car, you need a 16-25 gallon tank to go 400 miles...
I have a Tesla model Y and a Ford Mustang GT. I drive all over Texas in both. My mustang has a 385 mile range, while my tesla has a range of 357 (i have the long range premium model Y). 2 weeks ago I drove from Dallas Texas, to Woodville Texas, in my Model Y. Just today I got back from the same drive in my Mustang GT.
Much cheaper in the Tesla. It now costs me ~60$ per tank on the Mustang. I charge at home at night so unless i supercharge for long travel, my max fuel cost per month is 15$ - that’s right 15$ to charge every night, unlimited.
I supercharged about 2/3 the way to Woodville (it cost me about 7.50$), and supercharged on the way back (that as about 8$) - grand toal 15.50$. it’s a 466 mile round trip - so the Mustang it cost me about 76$ in fuel (@ 4$ a gallon)
What’s funny is Tesla Model Y is on around 170-180 watt hr/kg and i get ~ 350 mile range.
Now DOUBLE that - because with the new generation batteries that are already in production the are getting 250-310 whr/kg. - which would give a range of 550-620 miles. And they charge FASTER, to boot, at the same vehicle weight.
You guys who don’t own and drive both types of vehicles should at least ask somebody who has practical experience.
With this latest battery improvements (By the way, they use sodium, instead of lithium), the game is over. You might want to hang onto your muscle car though, as it will be even more of a collectable. At least until they are antiques.
so, you don’t need 12000 wh/kg, do you?
Quite some years ago, I would drive through Surprise, Az.
Somewhere around there there used to be all sorts of enhanced golf carts driving on the streets.
Electric Golf Carts in a golf community have proven themselves as very effective mobility devices.
Yes, we have those here as well. They can drive only on streets that have a maximum speed limit of 35 mph or less. And they must have lights and signals...........
Good dose of reality!
We’re getting ready to buy a model Y premium, too, and we have roof top solar.
Do you use FSD mode much?
Another problem with batteries is deterioration with discharge cycles.
200 charge discharge cycles typically lose 20-25% of charge capacity
If you were to go to the dealer after 2 years and tell them “I can’t get any gas into the thing. The tank held 20 gallons when new, now i can get barely get 15”
And they tell you “the tank shrinks with avery fill. They all do that...”
LOL ! Come on !
If people had the sole priority to save money on gas, they would all drive a Toyota Yaris.
The market verdict is clear. People do not want these things.
The only people who want EVs are politicians, bureaucrats, environmentalists, tech goobers, and the woke.
