Sorry to be the bearer of bad news, but that's mostly because it's a Chevy, not because managing lithium batteries in cold weather is an unsolved problem:

If you are in a climate where freezing weather is common, you might want to swap it for a different brand. There are comparably priced options that work well in the cold (just look at the chart in the article).

While I don't doubt other manufacturers have taken steps to charge better at cold temperatures, since theoretically you can do this if you have the charger warm the pack up to temperatures above freezing, this isn't just an issue with my Chevy.

All battery chemistry suffers from degraded performance in cold temperatures, because they all rely on chemical processes that are hampered by cold. Lithium batteries are in some ways more susceptible because they are just a more finicky battery chemistry overall, being far more sensitive to charging currents, temperatures, and voltages.

There's tons of articles and references out there about the cares that must be taken with batteries of various chemistries, and they all talk about the low temperature issues.

My Tesla definitely lost range in the cold, too. I don't think it's just that Chevy (LG, you mean) doesn't know how to make a good battery pack.
