Sodium-ion battery vanadium breakthrough brings energy density parity with lithium as it delivers higher continuous voltage. (www.notebookcheck.net)

I would have thought a key advantage of sodium-ion batteries is that it uses abundant stuff (sodium) instead of rare stuff (lithium).

Doesn't adding vanadium break that advantage?

Vanadium is more common than you'd think, actually. So, I'm not sure, but it may well still be cheaper.
