Sodium-ion battery vanadium breakthrough brings energy density parity with lithium as it delivers higher continuous voltage.

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?

I've always thought Na batteries had a lot of potential. I dont think they are the next power breakthrough but they are cheaper and easier to make/recycle than lithium. Aswell as longer lifespan during normal usage
