Long range electric applications will have to wait for nano flow cells to come into wide spread use. They are much like a battery / fuel cell hybrid and one will just use a filling station without the charge time wait.
I believe Li-ion batteries in hwy road going vehicles will have fallen by the wayside ten years on unless they are part of a hybrid system.
