The past 20 years have made lithium ion 2-3x more dense, both because of some chemistry changes and because of better pack level design.
And it's still improving at about 5% per year.

Tesla has been around for nearly 20 years. Model S (12 years) has gained 17% of range due to chemistry (rest is system efficiency and simply bigger battery).
BMW i3 went from 60Ah to 120Ah of battery capacity (and slightly more voltage) in the exact same chassis through the span of its life (2014-2022, RIP). It is even possible to put the later 120Ah batteries in the early 60Ah cars and reap the rewards, and is a practice that is actually supported by the cars' software natively.
Range is not a real issue for electric cars. Charging time is, though, and there are massive improvements happening for that right now.
Tell that to my polestar 2 pls. and then come back again in the winter when it drops another 30% due to the battery heater energizing

I would wager charging time is basically solved, adoption is only thing that's left.

Its a huge issue in cold climates.

This EV owner disagrees, and I imagine that city dwellers without dedicated charging agree
