Interesting link. My interest being more about volume than mass, lithium ion batteries have about 1/12.3 the energy of gasoline per volume. Does make for a better showing.
While volume isn't mentioned in the link, I'm surprised that supercapacitors fare so poorly per weight.
- cromwellian 12y agoOther interesting comparisons would be usable power. ICE is about 20% efficient, but electric motors are 90% efficient. So a lithium ion gas tank needs about 4x less energy.
- zurn 12y agoGood coal, diesel and gas plants reach ~50% in power generation (and marine propulsion in diesel case), rocket engines 60+% (thrust).
