It does, because the batteries for electric cars have a reliance on rare earth metals.
Lol the downvotes are hilarious. We will not solve climate change with electric cars. Public transit in walkable communities with niche uses for cars and trucks are the only way forward.
As seen in the Wikipedia article, sodium ion batteries also require rare earth metal anodes, or toxic materials like mercury which is also bad. Better than lithium ion, but still generally not great. The best option would be aluminum air batteries, which should be easily accessible and are extremely recyclable
The battery tech is starting to move away from rare earth, with LFP not using cobalt and sodium-ion not using lithium. And in any case, emissions are by far our most pressing problem compared to issues with rare earth extraction.

Hopefully there is a solution to that problem right around the corner.
