The Incredible Revolutionary Amazing Discovery of the Month! (To be not heard from ever again!)
As a technical person, I am skeptical of a battery only a few millimeters in size which can jump start a car. And if a tiny battery can put out 600+ amps, I don’t want it in my pocket. What is it, antimatter?
Very interesting article.
Please add me to your ping list Ace.

Abstract and, for a fee, the paper ($32 for a PDF!). But someone in the field might think it worth that price.
Seems to me nanorobots would be the ticket for making high-surface area batteries.
You’ve been added.
Love, Clint.
I want some answers::
what is the energy density of these batteries:: Currently, we are doing well indeed to get over 300WH/LB of density. There have been some 500WH/LB tests, but nothing on the market.
To get to 1000 times this...you are ow talking 50KW/LB.!! This is WAY more than GASOLINE!!
This would allow a battery of 4 POUNDS to have 200KW/H of power!!
Don’t forget some of the high-density formulas out there are ALREADY seeing “catastrophic energy release” of their energy, as fires and/or explosions. This is on UNDER 300WH/LB batteries!! Imagine a battery with say 300 KILOWATT hours of energy, “going up” on someones car!!
Converted into a few milliseconds of power—that is MEGAJOULES of explosive power!! Think of an IED!!
and to recharge all of this in “seconds” would require a LOT of power in—power produces heat. heat can be dangerous...
I love new technology, but the thermodynamic laws are hard to beat.

Free but not the same paper, just more info
I’m going to guess that they intend to stick a large array of these batteries into a larger battery case.
“To get to 1000 times this...you are ow talking 50KW/LB.!!”
Finally I will able to install Phaser banks on my Jeep.
If (!) true, this is insane. I want a laser gun :)
This does raise serious concerns though. Being able to carry that much power around, game changer in many contexts.
On the other hand, the same type of battery built into an appropriate housing with the needed larger conductors, and clamps to hook the thing to your battery would perhaps get the job done. But, even then, crank-time is likely to be very short, therefore not being what it needs to be when you're dealing with a hard-starting vehicle.
Bottom line - it's more hype than reality.
“The batteries owe their high performance to their internal three-dimensional microstructure. Batteries have two key components: the anode (minus side) and cathode (plus side). Building on a novel fast-charging cathode design by materials science and engineering professor Paul Braun’s group, King and Pikul developed a matching anode and then developed a new way to integrate the two components at the microscale to make a complete battery with superior performance.”
That’s nice, but they haven’t told how they work. I’m leaning toward thinking they’re an array of capacitors.
Of course there’s a plus and a minus. But how is the charge stored!
