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.
Yeah, I’m quite curious myself as to why it’s more difficult. My chemistry knowledge is chem1 level so all I know is that sodium atoms are larger and the energy levels for state change are slightly different
