For some reason Conservatives HATE EV's. I mean I understand that EV's are still improving and there ARE real problems with safety and environmental impact of Li batteries but as you noted and as I noted, there's new battery tech on the horizon.
Eons ago I was doing a postdoc on H2 storage for fuel cell vehicles. I went to a conference on transportation fuels in Norway and it was clear at that point that if H2 storage was "solved" it would mean fuel cells would become the standard for vehicles, but if it didn't get "solved" then it would always be a small segment. The intervening couple decades have shown that the solution to safe storage of H2 is yet to be achieved.
But EV's are improving and getting more popular. We got a Chevy Bolt with 300 miles on a charge and it is a FANTASTIC vehicle. We have solar on our house so we don't even pay for the fuel for the car! It's amazing.
Do I wish Li ion batteries were safer or less environmentally impactful? Sure! 100%. And I would GLADLY put my money to seeing that improve as opposed to our non-stop subsidizing of the petroleum industry.
