I do not understand that graphic at all. What exactly do you mean by "energy density" or are you referring to "power density"?

Diesel burns to create heat which is used for power. Lithium is used as a material in a storage system for electricity (battery) and does not generate any power of its own. Why don't you compare the energy density of diesel to say, lead? Or sulfuric acid?

And batteries can be recharged. Can't do that with liquid fuel.

Or teachers have failed us. They really have. We have went from a "it's a law of physics" society to "if we can just hope and dream hard enough we will make it happen" society. :R

Ok, so if you don't know what energy density is here is a guy that explains it in the most simplest fashion I can think of.

Just watch this video and then see if you can come back and truly say: LI batteries will work great in "long haul trucks like the Tesla Semi or even towing a small RV trailer." And please remember, this guy is not accounting for things like extreme grades, extreme temp swings, and things like that and many more that long haul trucks and RV'ers encounter.

Just wait till these guys show the Lightning up against lets say the new Chevy baby Dmax in a towing contest. See how far that baby Dmax can go. We already know the Lightning can go about 86 miles on a charge towing a small trailer.

If they do this, they should pick a route like 300 or 350 miles (the average most RV'er travel in a day) and see how long it takes for each rig to pull into a predetermined campground. Now that would be realistic and applicable for this forum.

Yes, logic is missing.

You still didn't explain your graphic.

Seems you aren't aware of the differences, so lets see if I can help.

Energy density is the amount of energy in a given mass (or volume) and power density is the amount of power in a given mass. The distinction between the two is similar to the difference between Energy and power. Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery. This difference comes from batteries being able to store more energy, but capacitors can give off energy more quickly.

Again, fuel burns (releasing energy), and lithium is part of a storage system. Apples to bananas. Lithium is rechargeable. Diesel isn't.

Your example doesn't make logical sense.
