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.
Their only downside is having a little less energy density than lithium ion ones. You need a larger battery for the same capacity basically. Everything else is a positive - they are even non-flammable and the materials to make them are abundant and easy to obtain.
Thanks. That’s awesome to hear.
Interested to know about durability also :-)
