>>A lithium-ion battery pack has about 0.3 MJ/kg and about 0.4 MJ/liter (Chevy VOLT). Gasoline thus has about 100 times the energy density of a lithium-ion battery.
Modern batteries have about 0.72 MJ/kg now. So twice that and EVs are about 3 times as efficient as regular gas cars so gasoline is only 15 times as dense in real terms.

EVs manage to get comparable range to their regular gas car equivalents by making the batteries very large.
