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.

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
