While the comment is funny, it is misplaced on an article that is refreshingly hype-free.
The title is full of hype.
Perhaps it could be better phrased to be clearer that it's "the highest of solid state batteries" and not "the highest of batteries, and also solid state".
---------------------------------------------------------------- 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]…
Is that hosted somewhere, or did you make it up just for this comment? It seems inspired by this classic: https://craphound.com/spamsolutions.txt

that only matters if you want a portable battery. there are alot of uses where it doesnt need to be portable at all. thats only for electric cars. same with crash resistance etc, and even affordability for average users.
it literally says "satellites and industrial machinery." in the article, neither of which needs to be very cheap or portable. especially because other batteries arent good under extreme temps
BTW: Whatever happened to those fuel cell proposals promising to replace laptop batteries altogether? I remember pictures of laptops running on working prototypes claiming to achieve 10 hours run time on a single "charge" 10 years ago. EDIT: Actually that's 17 years ago: https://www.techradar.com/news/world-of-tech/whatever-happen...
Apparently, after coverage in EVERY blog, news article, etc, they dropped it last year.

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.
I found it tedious. Pretty much every post about advancements in battery technology on HN have a similarly cynical post at the top. I wondered what this one would be before I clicked on the comments link.

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).
Still, it does make me cringe a little.

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.
This is true, the article is essentially 'cool new battery - for satellites'.

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.)

1) "Hey, that's great, I hope it works out for them!"
2) "Can I actually pull out my visa card right now, and buy some individual units online?"
Re: #2, most batteries have very little relevance to me as an end user until they're commercially available to buy. For instance the Panasonic NCR18650GA (245-250Wh/kg) li-ion, the Molicell P42A (21700 size li ion that's capable of being discharged at 45A rate with appropriate cooling), and other state of the art technology. I can go buy those right now from some reputable online stores.
Until whatever other new battery shows up to actually purchase, it exists in a liminal, theoretical state only.
