---------------------------------------------------------------- Dear battery technology claimant, Thank you for your submission of proposed new revolutionary battery technology. Your new technology claims to be superior to existing lithium-ion technology is is just around the corner from taking over the world. Unfortunately your technology will likely fail, because: [ ] it is impractical to manufacture at scale. [x]…

Yet another example of a glib response ignoring the actual facts in the article and ironic to boot given that lithium-ion suffers from several of the flaws listed. The funny thing is, none of the claims you make are correct and you miss the point where this tech is specifically designed to cover areas where Li-ion fails (like high temp and places where having a battery explode into flaming debris is a bad thing.)

also, dear technology journalist: [x] your description uses milliamp hours and milliamps per hour interchangeably [x] milliamp hours is a useless metric when we don't know how big/heavy said battery is [x] milliamp hours is a useless metric when we don't know the battery's voltage

At least it doesn't use milliamp hours per hour as a unit. I'm pretty sure one of the cars actually does that with KW (Kwh/hr).

Humour is rarely appreciated here, but I found this funny and on point. Battery technology announcements are always extremely over hyped. Mostly by media and PR departments rather than actual scientific or domain specific outlets. Advancements happen, but even if they are technically and commercially viable, it takes years until anything becomes actually useful.

Battery technology announcements are always extremely over hyped. Right, except this announcement specifically isn't. It's a short description of a new technology with targeted use-cases, which explicitly points out the ways in which it's not ready to displace existing technologies. You are correct that there is often unjustified hype around battery technology in general. But this article is absolutely not that.

Linus Tech Tips looked at a fuel cell USB supply a few years ago. It sucked horribly, and barely produced any power: https://www.youtube.com/watch?v=1-yLqwGS2dA Besides that, we can have 10 hours from a battery quite easily right now. If you need more, there are external batteries powerful enough to power a laptop over USB-PD. And after that you just charge it from any power outlet. It's a known technology, very matu…

That reminds me of mikeselectricstuff's teardown of a Hydrogen fuel cell power bank: https://youtu.be/y48wCuC3KcA An extremely well engineered piece of technology that may have been selling at a loss at $150. Only 26wh at up to 500ma, can't recharge it at home, have to drive to specific stores to pay £6 to swap the cartridge. Just completely impractical.
