A quick google search shows that gasoline has an energy density of 12,200 Wh/kg, or about 24x the battery technology discussed here, and without any dead load other than an empty gas tank, and no dependence on chinese spodumene.

Anyone with even a basic understanding if thermo engines knows that most of that energy is lost to heat and not available to power the car.
You can only cram so much energy into the chemical bonds of the appropriate elements for battery chemistry. The more you cram the more unstable meaning the more like fires or something more energetic. Research is to find the “sweet spot” between usefulness & instability. I doubt if you ever reach the energydensity of gasoline.
As TX Gator notes, a gasoline engine is only 25-30% efficient, so multiply that 12,200 by 0.25 off the bat. Now you’re down to 6x the energy density. Add in some savings due to regenerative braking and not needing a transmission. It’s edging closer to being competitive.
It means that I will get 60 miles on a winter say, instead of 50 miles.
