Energy density must be calculated from useful energy (work) after conversion loss. By that metric gas burned in an ICE is not much better than lithium batteries. The latter store less energy but it’s extraction is over 90% efficient.
Most of the energy you buy with a tank of gas goes to heat the air around and behind the car as you drive.
- andruby 5y agoThe weight of a full gas tank that can drive you 1000km is a lot less than the weight of batteries that can do the same. even if you include the ICE engine. In other words: even when you take conversion into account, energy density (both by weight and volume) is better in gasoline than battery. (I love BEV, and I see it will win over most of the market, but gas wins on energy density)
