I think CATL is promoting a hybrid pack of LFP and Sodium that would give you the cheapness and density of LFP, but with maybe 30% Sodium that you could use for a quick partial charge, and could also be used when the car is cold-soaked. Once you drive for a while, the whole pack gets warmed up and you can use the LFP.
Using lfp at low temp is not an issue. Charging is the problem.

Bjorn managed to get couple cars in coldgate condition - so cold and such low SOC that it's just not enough power to heat up battery and now you going highway at 60 km/h. IDK, maybe just a software fix, maybe an edge case, but it can happen.

Which also occurs while driving, whenever you're decelerating.
