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.
I find it interesting that, on a post about sodium ion batteries, your comment completely excludes them
Probably because they’re new and the parent comment specifically referred to the cheaper, less energy dense battery types.
The original comment was about lithium and their popularity for backup power. Sodium ion batteries are so new that you can’t purchase them yet (blueitte supposedly released the NA300 but I can’t find any in stock and it’s no longer on their site).
It wouldn’t be fair to compare a chemistry you cannot purchase and which it’s strengths and weaknesses haven’t been tested outside of controlled laboratory testing.
Fair point - I’m not really that good with the physical sciences personally so apologies for my ignorance
