The og&e-ligarchs are trying to flood the internet with lies or 1/2 truths or furry porn, it’s s/madhouse.
Ultracaps don’t poison the environment when made right, are 100% recylable, don’t burst into thermite flames when punctured and last longer by decades than Lithium anything… They are however less energy dense at the moment (but lighter). So with a larger volume, you get all the environmental benefits, but slightly less mileage - however you can charge it way faster than a lithium. They combime the two to get the range, but lithium is still toxic and less recyclable. 🤷
