Is this not less about the LFP lifespan per say, but more about the extended abilities of sodium battery tech? To my understanding it can withstand extended temps better. No need to have heaters above freezing…
FWIW latest LFP's can withstand cold too. And both Tesla and others have been using some sort of "ripple" frequency to internally preheat cells when on supercharger, for a while now.
All that said of course not having to do that is great. Cost parity is not going to be there for 10-15 years tho.
