There's so many assumptions in this.
I don't know that a car with a sodium battery 100% by default has to have less range than one with NMC.
Like sure ok, assuming you go with an identical physical size pack, and the cells themselves are identical size, then sure the better energy density of...
By your own admission CATL's sodium batteries are roughly on par with the energy density of LFP batteries.
Ford, Tesla, Rivian, GM, Nissan, Stellatis and others are either currently selling cars with LFP batteries or planning to do so in the next couple of years.
So by your logic, those...
An nmc in the cold will have less or equivalent range to the sodium battery at substantially higher cost
So the sodium car could afford to pack a bigger battery in there for the same net cost to the consumer.
But yeah I agree it's not a suggestion for today, it's for the future.
I also...
I don't see any companies in the US or Canada marketing ev's specifically geared towards cold climates.
This is a niche someone will eventually exploit, why not be the first?
It's a pretty straight forward sales pitch: most ev's lose roughly 40% of their range in extreme cold like that found...
