What about solid state batteries that can charge in 2 minutes instead of one hour? And have better capacity and a longer life?
As soon as they figure out how to actually mass produce them at an affordable price, and fix the swelling issues during high charging currents, they'll be available.
They've been as good predicting when this will happen as Elon has been about FSD.
It's always just around the corner.
Although it really does seem like we might start seeing soon this time at least in low volume expensive things.
this article is about changes to solid electrolyte only, you'd know that if you read the article. these have less conductivity ( = lower power density) tho
it took 9 months of real lab work by real material scientists just to make it work, things like dendrite formation or swelling aren't part of this optimization (well at least AI stage), the linked preprint doesn't even mention dendrites once
Oof. You got me there lol.
I read the article and this one line stood out.
This isn't new I think. Sodium-ion batteries were already known. Maybe there was still dendrite formation and this recipe might reduce or eliminate that? We'll have to wait and see.
In any case, if it can drastically reduce lithium usage that would be good progress.
sodium isn't electroactive there tho, it's just a part of electrolyte. also dubious if you can make savings on lithium work if one option for anode is solid lithium metal
I want a semi-solid state batter that turns kinetic energy into stored charge. I want to be able to drop it on the ground, fire a .45 round into it, and have it immediately be fully charged.
