With both battery designs, it’s not the electrolyte chemistries that are being drastically altered, is the anode & cathode design that is receiving a lot of attention.

I think this is a little bit misleading. While Jet fuel is incredibly energy dense, jet engine designs convert only 30-50% of the energy stored in jet fuel into mechanical effort.
I’m not certain what the power efficiency of an equivalent electric based propulsion device would be, but I believe the losses within electromagnetic motor designs are much lower.
That doesn’t exactly close the gap between energy densities, but it does narrow it a lot.

We need r/TheyDidTheMath on the case to prove that.
Commercial airliners never fly on empty, and you can’t gain more jet fuel by covering planes with solar panels they way you can with electricity.
The technology isn’t there yet, and I’m not suggesting it is. My suggestion was only that the energy density numbers don’t tell the full story because of inherent losses when using that energy source.
