@wigwam There’s no need rewrite the laws of physics batteries like that are coming. Samsung have a new battery due out very soon that doubles energy density, so same capacity but half the current weight so the car would also go further on the same size battery or same weight but double the range.
Outside of that the guy that invented the lithium cell John B Goodenough (absolute legend & genius & the best name ever) his lab are working on glass batteries that have something like 8x capacity & do charge in minutes vs hours.
There’s quite abiy of info out there on these glass batteries & despite the glass they’re much safer as the electrolyte is not flammable.
So this stuff is coming might be a few more years but I think we are on the cusp of some truly breathtaking battery tech
