I was expecting this to be about thermal performance rather than climate impact. The fact that you have to dump energy to heat LiIon batteries for safe charging or use in cooler weather is nuts to me. How's 0°C performance of Lithium-Sulphur?

I'm pretty enthusiastic about LithiumIronPhosphate prismatics in cooler regions even if they're a little more heavy.

I look forward to have more choice in battery chemistry when buying a new car. Depending if you live in warm or cold weather and if you do mostly short or longer trips, you should be able to choose what battery is best for you. But at this point Lithium-ion is still just the cheapest option due to economy of scale.
