최초의 나트륨 이온 배터리 EV는 겨울철 주행 거리 괴물입니다
The First Sodium-Ion Battery EV Is a Winter Range Monster
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.

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