The first EV with a lithium-free sodium battery hits the road in January - Sodium-ion batteries have lower density but are cheaper and perform better in cold weather::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.
For EVs, these batteries are better for the environment to produce and to dispose of, and if you’re able to replace them every time you go to a recharge station you’ll never have a battery die because it won’t be in your car long enough. The batteries keep rotating until they die and then they get taken out of rotation and disposed of.
