As long as the lithium ion battery is the best we got, there will be no mass replacement of combustion engines with electric. There simply isn't the energy density. Also, lithium supplies aren't sufficient.

Energy density isn't nearly the as big a problem as lifespan and cost. You have to move some things around, but if you stick the suspension and the engines in the wheels, there's room for > 500 liters of battery in most cars. Th!nk gets about 150 L in a microcar.
