Other “gotchas” on these new wonder batteries is temperature range and self-discharge rate.
Holy kilowatt-hour, Batman.
Can we do this at home with any phone battery?
Keep in mind that an ICE burning gasoline has about 30% thermodynamic efficiency, so -- in terms of usable energy to, e.g., drive a car -- it's in the ballpark.
“What does IBM make today that you would buy from them?”
I recall Panasonic used to make bicycles, apparently IBM is into them now.

Great news! Global Warming\Sea Rise solved, lol
you beat me to it, lol
Children in the Congo are slaving and dying in lithium mines to provide the raw resource for these batteries. Liberals don’t care because they love their iPhones. These products are extremely harmful to the environment, but liberals don’t care because they love their iPhones. Someone is making serious bank by enslaving or promoting the enslavement of these poor black children. Who?
One other area of concern... Sure the battery tech can support an 80% charge in 5 min... But what about heat dissipation during that time? Consider a Tesla has an 85 kWh battery. That's an awful lot of energy to deliver very quickly. A Tesla supercharging station delivers about 150 kW of power at 480 volts. That works out to about 300 amps. That takes 40 minutes to charge. If you want to deliver the same energy in 5 minutes... You're going to need more volts and/or more amps, about 7X more of one or the other. I would say both are already at the fairly scary-high level right now with a supercharging station.
LOL - I had a typo in this briefly in the last sentence. It said "...supercharing station." Which at these levels of power delivery might not be a typo after all...
Sorry...couldn’t resist. :)
whats per litter?
Me neither:)
I’ve seen survival shows where if you are in a situation where your device can’t help you any other way (emergency phone call etc) and you need warmth and Fire you poke your battery.
Hopefully the amount of seawater needed to produce these will offset the rise in seawater from global warming. This would be be a two-fer. This would be a liberals wet dream..
No mention of who the researchers are. Just curious, I spent 8 years at IBM Research, before moving to the product division. Lots of smart people there.
But, it was (I don’t know about now.) as cut throat as you can imagine. All researchers were appraised on a ranking system. Everybody was “on the curve”. Talk about apples and oranges. It was the three “P’s” that got you to the top. Patents, Publications and Presentations.
Just FYI.
Worse than that is when we find out it is real and it works but it is a cryogenic technology.
This is why they make links to articles. It says they are extremely stable and have no heavy metals. The performance is about the same as Lithium Ion batteries except they charge faster. But the point was to escape Lithium and to avoid the combustion problem.
What isn’t said is does it have the same or better life (number of cycles) and is the cost going to be the same, less or more?
You know, I didn’t see that. But, they are trying to make the point that the ingredients are environmentally neutral. But, other than water, there are many millions of tons of sea salts already dried out and ready to go. I can’t see where that would be a problem. But, my guess is that the laundry list includes elements that are in sea water rather than needing sea water to make them.
IBM can’t make an announcement like this without some pretty deep certainties about the technology. This is a signal to the Stock market and a fraud in this sort of thing would have serious consequences.
As for price, good question. Dunno.
Availability, it could be a decade from now when this comes out but I doubt it.
My dad used to get the IEEE proceedings every month and this was full of wonders being announced like this IBM product. And, then it would take more than 10 years to see any products based on these technologies. The reason patents are designed to expire in 17 years is to allow time for a technology to be developed which can take nearly a generation.
If you were worrying about gas tank size, the energy density of gasoline would be a worthy issue. However, it takes misreading the meaning of this specific measure to mistake this as a fuel quality. This gets to the size of battery required to offer a specific number of watt hours of energy. Lithium Ion batteries have revolutionized device design by the energy densities, Small Battery Sizes, available.
My Apple AirPods are ridiculously small because the battery that powers them is insanely small. But, my first pair died in two years because of cycle life. I loved them to death. So everything works but you have to break them to fix the battery. Suck!
Prolly.
