you would know that if you read the article. they replaced part of lithium in electrolyte with sodium, so that they can use less lithium. the problem is decreased ion mobility ie less power density in real life terms.

Baker and Murugesan both say that lots of work is left to optimise the new battery.

bet

i'm gonna mostly ignore this finding because it sounds like extension of AI hype. real lab work is still absolutely critical in order to make it work

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

And have better capacity and a longer life?

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

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
