Sodium-ion batteries still don't exist yet. And even if they do, they will be much lower energy density than li-ion. EVs will get heavier, not lighter.

- timbit42 4y agoSodium-ion batteries are approaching lithium-ion battery density. Researchers think they can reach and surpass lithium battery density, but that seems unlikely. Until that happens we should switch to sodium-ion batteries for stationary uses, such as in homes an businesses and leave the lithium-ion batteries for portable usage such as vehicles and portable electronics.
