There is nowhere near enough lithium on planet earth to make lipo batteries to equip even a fraction of the worlds fleet.
We need something else, some other type of battery, maybe if Europositron ever comes out with their aluminum battery (plenty of aluminum in the earth!), as it is supposedly cheap as dirt to produce, and has energy densities up around 1500Wh/kg! A typical lipo pack we use is around 140 - 150Wh/kg. IIRC, it would cost something like $3000 to have a range of 1000miles in a typical car.
