Do 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.

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.

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.

Any US automaker relying on Trump staying in office is playing with fire. Yes, you may see reduced or zero press releases and budgets for EV research being "reallocated" on paper so the toddler in chief doesn't get a public tantrum - but assuming there will be free and fair elections this year, it is highly, highly likely that Congress will be solid blue and reinstate a lot of what Trump has cut down, only this time as an actual law that is far harder to cancel than executive orders.

And everyone not hedging for this possibility will wreck their company's future.

What did the administration say to them?

[jillesvangurp]

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.

It’s only “fine” if you live in the southern US where freezing conditions are rare and/or never drive anywhere near your winter range and you have a garage charger or some other easy access to a charge station. Anything outside of those conditions and winter range issues are painful.
