alt Hacker NewsDo any US automakers have anything in the pipes using Sodium-Ion batteries? A quick search turned up info on a plant mass producing the batteries in Holland, MI but no mention of when they would be available. As someone in the market for an EV within the next year or 2, and also currently enduring a month long stretch of temps in the single digits and below, cold weather performance has suddenly become a huge consideration.

LFP battery production in the US only recently reached larger scale; so I expect it will be a while before they get around to sodium ion. With all the tariffs, they'd have to license technology and build local factories to get started. That will probably be a few years at least. Or the tariffs might become more reasonable at some point and they could import battery cells a bit sooner than that. But probably not until the end of this decade.
Cold weather performance with heat pumps and lithium batteries is fine. Don't worry about it. I wouldn't try to hold my breath until a US automaker produces a sodium battery EV.
If you remove Tesla and Rivian from the equation, US automakers are actively curtailing EV production period.
The US administration has basically told them to do so.
So don't expect any innovation on this front from the middle of the North American continent. It's being actively sabotaged.
Likely No. Undecided with Matt Ferrell recently did a video on how sodium ion batterys startup in the US (not necessarily for EVs, but other power applications) have had challenges largely due to the falling price of lithium making sodium batteries less competitive on price the past couple years: https://m.youtube.com/watch?v=nrTCgZmUFCY
OTOH, there are seemingly more lithium iron phosphate (LFP) battery ev options now - rivian now uses LFP, Ford mustang mach-e has had a LFP variant since fall 2023 (and should have other models using LFP in 2027), I think the 2026 chevy bolt uses LFP, etc.
