It's really not about energy density at all, it's more about the reusability of batteries and charging them in the most energy efficient manner.
There's a reason it only costs 6 bucks to drive 300 miles in a tesla.
And it would help tremendously, of course, that new Li tech potentially will allow triple the capacity.
