Batteries: Higher energy density than gasoline?

Energy Policy, 2009, vol. 37, issue 7, 2639-2641

Abstract: The energy density of batteries is two orders of magnitude below that of liquid fuels. However, this information alone cannot be used to compare batteries to liquid fuels for automobile energy storage media. Because electric motors have a higher energy conversion efficiency and lower mass than combustion engines, they can provide a higher deliverable mechanical energy density than internal combustion for most transportation applications.
