I am not sure about which cells are better or worse, but there are cells
which have problems with the Li plating onto the graphite electrode if
there is too much current at lower temps. This clogs the electrode so less
and less can be intercalated quickly.
Lots of interesting literature in this se

That's true. But the efficiency of good EV cells is high (95% or more)

I know that Lithium batteries perform worse at lower temps. But what does
that mean?
Charging, or using? which is worse.
For example, in the winter, is it better to charge in the evening when I
come home and battery is warmer or to put it into charge-by-7AM mode and
have it charge the battry wh
