In the last 10 years, the tesla platform and all of it's advancements and revisions in that time has only improved KWH/Kilograms by 10%, and increased the size of the largest battery available by just 12%.
They can make a battery bigger just by adding cells, but that's then like saying I can make a plane fly further by putting in a bigger fuel tank. That's not a scientific advancement, it's simple physics of scaling, and you get diminishing returns on efficiency when you do that.
At the current 10% per year energy density improvement, we are 80-120 years away from getting where we want to be on power to weight of battery tech replacing liquid hydrocarbon fuel.
