...costs only 20x as much!
If by “last 20x as long” they mean the storage capacity and not the useful lifetime of the battery then this is truly awesome!
It would make super long range battery powered drones possible and even small, electric engined general aviation aircraft a real possibility.

I just LOVE miracle battery stories. Must have seen at least two dozen in my lifetime. I love them almost as much as the nutter LENR posts that invest FR.
Given’s Murphy’s Law, once mass production begins, prices should come down dramatically.
This is great news for Tesla Motors... a breakthrough lithium-ion battery would mean faster recharging time and a more viable electric car.
They have been waiting for this breakthrough and they will try to get it on the market faster.
I hope this is true, but I won’t believe it til Tesla Motors adopt this. Theres been lots of hype in regards to batteries over the years, getting me excited but never hearing about them again
That’s tremendous.
plus, besides the wild claims, poor grammar, etc., what the heck does the journalist mean by “...the clinch, is...”
What does this mean for the capacity? Will that also be increased?
Does this mean the first iPhone to use it will cost $5000?
I can see the new president of Apple rubbing their hands together over the millions of people that are certain to pay that on release day.
the only place batteries have in a car is powering the starter and lights!
Some of the better AGMs will charge fast (low internal resistance).
“charges 20x faster, lasts 20x longer”
But not at the same time...?
Well, now, let’s do a little simple math.
Let’s say we have a 2000 mAh battery that will accept a charge current of 500 mA, and it takes 5 hours to fully charge (there are always substantial losses in the charging process.) If said battery can be charged 20x faster (ie., in 15 minutes), our charge current is up to 10 amps. That’s a MUCH bigger, more expensive charger.
Similarly, if the battery has 20x the capacity (40 Ah), given the original 5 hour charge time, again, charge current is 10 amps.
If the battery has 20x the capacity and can be fully charged in 15 minutes, then charge current is 200 amps.
Obviously, the battery banks needed to propel vehicles are MUCH larger. The recharging stations could be quite, uh, interesting. Plus, heat dissipation in both the charger and the batteries being charged would seem to be a very large concern.
It would be fantastic, but I’ll remain a sceptic until we see these things hitting the streets.
A battery which has 10x the capacity of today’s batteries which could still be charged overnight, let alone in a few minutes, would have a significant impact.
I’m quite happy to move off of dino fuel and if there is a break through that legitimately enables that transition - great! But I remain a sceptic until I see the proof.
How hot does the battery get on that 2 minute high current charge?
I will be able to refuel my gasoline car in 2 seconds once I install a 6-inch filler port in the car, and the gas station installs 6 inch filler hoses.
Just as an example, can you imagine the electrical cabling required to pump this much energy that quickly into a battery? And the waste heat that is involved? The details always getcha..
OK. Let’s say this battery is capable of taking a 70% charge in 5 minutes. How much voltage are you going to have to push into it, to charge up a car that fast? That’s a hell of a lot more than 220v going in. I used to know how to do the math on this, but it’s been so long I’d have too look too much stuff up. I’m pretty confident a Freeper can give us a good back of the envelope calculation for this.
