This is still good and should be looked at seriously to recover the lithium already in circulation, but I can’t help but feel like this is coming at the end of lithium as a battery material. Sodium batteries seem posed to supplant it in the near future.
Sodium batteries aren’t seriously expected by anyone to supplant Lithium ones. The two things Sodium can theoretically do better than Lithium are being cheaper as a raw material, and working well at low temperatures, but it’s always going to be heavier and larger for a given capacity. Most applications for batteries care about their size and weight, and so the extra cost of Lithium will be worth paying.
Chemically, Sodium and Lithium are very similar, so any improvement that applies to one should be pretty applicable to the other. That’s actually one of the main strengths of Sodium batteries - most of the research that’s already gone into making Lithium batteries can be reapplied with minor tweaks. However, Sodium is inherently larger and heavier than Lithium, with fewer atoms fitting into the same space and those atoms weighing more. If research for Sodium batteries catches up with Lithium ones, they’ll still be worse just because of that, and at that point, research would get easier gains from improving Lithium batteries than Sodium ones.
There are improvements but physics and chemistry kick in at some point. I don’t know enough to presume where that point is, but you seem to be presuming that the limits for sodium will be better than lithium and I’m not seeing any evidence provided, just faith. May as well work with the reality we have while we see how that pans out. Like someone else said, we recycle a lot of lead from lead batteries, we didn’t stop when lithium batteries came along

That assumes research has stopped on sodium battery chemistry.
