I imagine in 20 years a lot of solar cars, using such batteries, and many homes with solar panels, all connected in grid.
Battery don't need to have the same energy densit of gasoline. Anyway the gasoline have 1/3 of the energy reported, since the reported value it's for the bunring it with oxigen, and the gasoline itself only have 1/3 of the energy of this combination of gasoline and oxigen.
Second the electric motor it's much more efficiente (up to 98%) than combustion engine of cars (about 25%).

CAR and DRIVER,in November,2016,mentioned Sam Abuelsamid,of Navigant Research, predicting that EVs would be at cost parity with ICE around 2025.
The reasoning was that,a BEV motor,electronics,and pack would have the same cost as an engine,transmission,and powertrain,by that time.
This is without any magic.
