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 had to go look it up because fuck an article being clear to layman about shit.
3C to 4C charging means that it goes from 10% to 80% in roughly 20 minutes. No word on if the battery has a longer cycle life than current lithium ion batteries, or anything else most consumers would be interested in knowing. But hey, good to know someone out there is working with sodium batteries in a mass production way.
I think the thing with these sodium batteries is they are less energy denss than even LFP batteries.
LFP are great for standard range vehicles and are in a lot of the lower tier EVs and the nickle ones go into the long range versions.
But these should be even cheaper than LFP which is cheaper than Nickle.
These would probably make it easier to make cheaper commuter cars, where right now the price/range ratio makes them a harder sell
No clue about cycles.
