I would worry about how much energy is expended maintaining the temperature.
I realize this will depend in part on insulation and size (SA/V). Which makes it a bigger issue for space-constrained (e.g. automotive) batteries. Also a bigger issue for the really-high-temperature ones that would soften fiberglass.
Should be possible to use reasonable assumptions to put some sort of numbers on this...
Great discussion as usual. What about adding CATLs sodium ion battery which is on the market now. With their size CATL could upend both transport and stationary storage....
