In the superheated market for batteries, promising lab developments often get overhyped by startups. ‘Liar, liar, battery supplier.’
Given what’s at sake, it’s easy to chalk up exaggerated claims about new battery breakthroughs to the tech industry’s propensity for hyperbole and grandstanding. A typical example: Researchers invent a tweak to a type of battery that has long shown promise but has never come close to commercialization. That gets spun into claims that an electric car with a 2,000-mile range is within reach.
“People like a breakthrough, but when we write papers we try to avoid using these kinds of words,” says Xin Li, a researcher at Harvard University whose team recently published a paper on a new kind of higher-capacity solid-state battery in the scientific journal Nature. “There are too many battery ‘breakthroughs’ in my opinion in the past 5 years, and not many can be implemented in a commercial product.”.
“When we started Tesla in 2003, the batteries were just good enough, but what we had noticed was that they got better at about 7% to 8% a year, and had for a long time,” says Marc Tarpenning, a co-founder of the company. “It’s been 19 years, and we still haven’t had a step change in battery capacity—it just ticks along at 7% to 8% per year.”
At Harvard, Dr. Li’s team has worked out a new way to make solid-state batteries last longer. In theory, this could make the current combinations of elements that go into batteries yield a product with much higher capacity, and way down the road, it could be used in concert with other novel chemistries, like lithium-sulfur, to take auto- and gadget-makers to some sort of high-performance battery nirvana.
But Dr. Li cautions that commercializing his team’s technology will take years...

“ The “filling stations” would just replace your battery”
Ther was a video from Tesla some time ago where they demonstrated this very thing. You pull into a bay like at jiffy lube. They unbolt the battery core from the bottom of the car and swap it out with a charged core. They showed it in split screen alongside a normal car filling up with gas. The battery swap was about a minute quicker than the fill up. Pretty cool. I can’t imagine what it would take to set up enough of these stations. Of course back in the day you didn’t have gas stations on many corners like now. Maybe in a few years there will be such a system in place.
And still no USA profits. Plus, I don’t know what the total NOL is at the federal level. So it will take a while to be profitable with no subsidies, and he liable for fed taxes.
“To save the erf, EVs must be made only from naturally occurring material. Think Flintstone car. Hmmmm. No battery.”
Other than one scene in Barney’s car (which used a small dinosaur), we never saw how the Flintstones powered their cars. About the only thing we know is that they didn’t have transmissions, because they had to kick-start to get them moving.
SaxxonWoods wrote: “Should be faster than filling with gas easily.”
A battery pack weights at least 1000 pounds. I find it difficult to believe that battery packs can be swapped out in less than the few minutes it takes to fill with gas.
“We’ve cut auto air pollution to nothing compared to 40 years ago. What’s the problem?”
The Democrats don’t approve of gasoline anymore.
“My actual Rocket Scientist BiL has been saying that for years.
My addition was that the manufacturer doesn’t even provide a battery. You lease the right to use batteries from a separate company that specializes in batteries and “Switch Stations”.”
The reason why even Tesla doesn’t discuss it is because you’d have to depreciated the cost of the batteries with each swap-out, and that cost is about twice the cost of the power to charge them...and roughly makes their per-mile driving cost no different than gasoline engines, thereby losing its main advantage (other than bragging rights at parties).
So, not going to happen.
“How long you figure to replace ‘your battery’?”
Not to mention the labor charge and capital investment required...all for a new charge that otherwise costs $5 to $10 for the electricity.
“How long you figure to replace ‘your battery’?”
And then the inventory required. How many types, sizes, and forms of batteries, and how many to stock of each? Batteries weigh close to 1000 lbs (or maybe more in some cars), tougher than changing, say, wiper blades.
My thought is that it’s one thing to store a flammable material in your vehicle for as a power source (gas), but it’s quite another to store both the flammable material and the oxidizer together (bomb).
—”Think of those people riding around in the self-driving models as test pilots. Dangerous job.”
Late Saturday night it is believed that more than a third of the drivers are impaired.
Better they were all in FSD autos.
And as a young septuagenarian, my RT (reaction time)can easily be measured on a kitchen clock.
Relax and enjoy the ride.
video is about poster's Y zeries but the self drive package is common across offerings.
Aren't the batteries to run an EV 100s if not 1000s of pounds. And they are quite large. It would still be a huge hassle to switch them in and out.
On Teslas the battery is actually hundreds of small batteries a little larger than a AA.
The biggest lie they tell is they “Lie by Imply”.
Every article on EVs as well as Solar & Wind make it sound as if EVs, Solar & Wind are like what computers were in the 1980-1990’s, that is they imply these are some brand new technologies on the verge of incredible breakthroughs and quantum leaps, just only if those nasty Republican buggy whip manufactures would get on board and we just spend more money investing in them then the future is unlimited.
Wrong, the 1st Electric Car was invented in 1829, fifty years before the 1st gasoline powered car (Benz). The 1st Roof top Solar installation was in the 1860’s twenty or so years before the 1st Coal fired electricity generating plant, and Wind power is so old it is mentioned in the Bible.
These are not new technologies with an unlimited future, these are old outdated technologies already at or near their maximum potential and were passed over for fossil fuels for very good reasons.
Battery Weight by Telsa Model
https://themotordigest.com/how-much-do-tesla-batteries-weigh/
Roadster: 992 lbs (450 kg).
Model 3 Standard Range: 1054 lbs (478 kg).
Model 3 Long Range: 1168 lbs (530 kg).
Model Y: 1168 lbs (530 kg).
Model S: 1377 lbs (625 kg).
Model X: 1377 lbs (625 kg).
You wouldn’t be replacing individual AA sized batteries
Well. No.
You need to put in100% power to store 92-85% of that power. Then you get out 90 to 85% of the power you stored. Net loss of 15-20% in the go-get-get out power. Rest is chemical and heat losses.
It’s these conversion losses they are trying to reduce.
—”Did you know the Tesla Auto Drive software package is a $10,000 option?”
So I have noticed.
Honda has had FSD in Japan only for over a year and maybe ahead of Tesla?
A different approach from Tesla, only functions for city driving; for now.
Other manufacturers are not asleep at the wheel...
Market forces will push the cost down...I hope?
“We’ve cut auto air pollution to nothing compared to 40 years ago. What’s the problem?”
The “problem” is that you still have personal freedom to travel at will.
It’s not an environmental thing. It’s a control thing. They want to be able to control when/if you can use “your” EV so as to force you onto public transportation and into cities/suburbs to keep a better eye on you and your social credit activity.
