For comparison, li-ion 18650-size 3500mAh cells are 260Wh/kg, that is almost +50% capacity per gram but only +15% capacity per volume
Drone batteries then
Or car batteries. EVs are still heavier than ICE vehicles and road wear goes up by what was it, the 4th power of axle weight? Even at the exact same capacity per volume, an increased capacity per weight is a huge advantage. Not to mention that the car itself needs to have beefier suspension, tires and brakes for more weight (even though yes, on the braking side, EVs get regen braking - they still need to be able to stop quickly if something happens to the drivetrain). Also no danger of battery fires.
If this works out AND charge/discharge rates are good AND production scales fast enough, this could be huge in a few years. Of course it might also not be.
The incredibly unbelieveable smells-like-bullshit donut battery hit an even higher Wh/kg (not by much) in the new VTT test, but there’s still no guarantee that every test’s been on the same type of cell. Current leading theory is that they’re just taking a bunch of completely different cells to be tested and the solid state one might not be the same one that did all the other tests.
Only if power density is good enough
Didn’t we literally just establish that the power density is higher than Li-Ion?
that’s energy density, maybe you can only discharge it only over 20h without damaging it or something (probably not but there are so many places where things fail). power density was not reported there
I’d have thought that the weight would be the deciding factor
Ultimately yes. People easily get confused between power density (power per volume), energy density(energy per volume), specific energy(energy per mass unit) and specific power(power per mass unit)
Can’t imagine why…
Still…
I understand that these things are perhaps less flammable because no electrolyte that burns, but also there’s a question about efficiency, manufacturability, overheating, charge depletion in time and across cycles etc. Maybe it’s not even any good
Sure. And, given how people tend to hype stuff which never works out, it probably isn’t. But, sometimes it is, so… maybe?
it’s nice to find someone who gets it in the wild. i’ll give you an example: 90% of clinical trials fail, and it creates a predicament: some news site grabs a headline from university press release, which is informed by a paper. paper says that maybe there is some effect in cell line, if you use some new compound, against some kind of cancer. sometimes it grabs more attention if it’s a compound from common plant because of folk medicine connection. press release: university w made a compound y that kills cancer z. article: university w makes a drug for cancer z. clickbait youtube video: underdog researcher DESTROYS ALL CANCER. naturally, years pass, compound goes through extra testing and in most of cases, fails, many times even before it ever touches humans. sometimes it doesn’t work, sometimes you need quarter of body mass of it to see effect, sometimes it wipes out liver, sometimes it does something else entirely. then clueless people looks back at these headlines, and ask, where is cure for cancer z, or sometimes even where is cure for all cancer. the stupid and embarrassing reality is that it never existed, because it was at best toy compound and maybe someone develops something out of it, but mostly it won’t. some people take it as a sign of conspiracy that suppresses inconvenient TRUTH and there is a cure, but you can get it only from a BOLD RESEARCHER THAT THREADS WHERE NO ONE ELSE DARES. then we get clinics ran by scammers and a lot of dead people
that said, there’s already a lot of things, mostly moving things, that can be electrified with current technology. it would be a nice thing to have something better, but it’s not like it’s strictly necessary to have it
You worked in Pharma too, huh?
Well put.
there are dozens of us, dozens!! (closer to third of dozen)
wdym worked? i don’t think i’ll ever retire
I was in briefly around þe time þe last MD C-level at GSK was replaced by a marketting wonk; a bunch of people I liked started trickling off, a couple got laid off, and I headed for greener pastures. Pharma wasn’t my domain anyway, so I had no real career ties. I did learn a hell of a lot about drug development, and þe research process (specifically, þe business side). I was pretty young at the time and bought into þe whole “we have to charge a lot, because it’s so expensive to develop drugs” until a director a couple of levels above me said, “don’t feel sorry for the company. They’re making plenty of money.”
In a weird twist of fate, my wife, whose background was even less medical-related þan mine, found her way into þe medical device field, only she’s stuck wiþ it. So I now know more þan I wanted to about med devices þan I ever þought I would, too.
