요약

Changan Nevo A06은 나트륨 이온 배터리를 탑재한 최초의 양산형 전기차로, 추운 날씨에서의 성능이 크게 향상되었습니다. 리튬 이온 배터리와 달리 -40도에서도 주행 거리 손실이 거의 없고 열 폭주 위험이 없습니다. 에너지 밀도는 LFP 배터리와 비슷하지만, 뛰어난 저온 성능과 저렴한 비용으로 EV 및 에너지 저장 장치에 대한 유망한 대안이 됩니다.

If this is “on par” with LFP energy density, I’m not sure there’s any need for LFP now. Sodium ion seems to thoroughly beat it in every other metric.

I haven’t seen any info on charging speed. Can you recharge these as quickly as LFP?

On par on a per kg basis, but is it on par on a volume basis? If it takes up more space, that might pose packaging challenges relative to LFP.

I suspect we will be finding this technology being used a fair bit in aerospace tech like satellites to compliment the onboard solar, given the low-temp operational capability.

Do satellite batteries run cold?

Given the difficulty of radiating heat away I would have expected the opposite.

Especially considering the incentive to send up as little battery as possible, and the very predictable day/night cycle leading to the ability to precisely predict how small a battery you can get away with...

What I wanted to know from the article:

  The CATL Naxtra sodium-ion battery will debut in the Changan Nevo A06 sedan, delivering an estimated range of around 400 kilometers (249 miles) on the China Light-Duty Test Cycle.
and

   It delivers 175 watt-hours per kilogram of energy density, which is lower than nickel-rich chemistries but roughly on par with LFP

Retaining 90% range at -40°C sounds like a game changer, almost too good to be true. I'm definitely going to need to see some third-party real-world range tests to validate those claims before getting too excited.

“As always, we’ll have to wait for independent testing for real-world results.”

interested in hot desert weather performance which often gets lost in the averages.

I don't understand what these headlines are really about, given that 75% of the range loss in my EV is from CABIN climate control.

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.

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.

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.

Nothing in the article really substantiates the headline (currently "The First Sodium-Ion Battery EV IS a Winter Range Monster").

The EV described in the article has a standardized range of 250 miles. This isn't a range monster in any condition. There is some gesturing that Sodium batteries don't require as much active heating in cold conditions. But nothing is quantified.

As usual with sci-tech broadly and batteries specifically: it's exciting that sodium batteries are coming to market; we can be optimistic that maybe in the future they will provide lots of range, or be less expensive, or maybe less flammable than today's lithium batteries. But the marketing hype is running miles ahead of reality.

The marketing hype is the true range monster

It makes this claim:

"The Long-Range Version sets a new record for light commercial vehicles with a single-pack capacity of 253 kWh, achieving a maximum range of 800km."

That would be some 720 km at -40 C if the numbers are correct. I'm not well versed in this area and not sure if these batteries are comparable to those in personal vehicles, but the ones I've heard owners talk about have a reach at about half that if it's cold at all.
