JAC Motors, a Volkswagen-backed Chinese automaker, unveiled the first mass-produced EV with a sodium-ion battery through its new Yiwei brand. Although sodium-ion battery tech has a lower density than lithium-ion, its lower costs, simpler and more abundant supplies and superior cold-weather performance could help accelerate mass EV adoption.
The other thing is that it could also potentially be significantly cheaper to replace if it wears out. And could potentially be easier to recycle too, if it’s common salts. I’m optimistic about it!
