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%).

The focus for the last 40 years has been to cram more power into a smaller space and try and do it cheapy.
Electric cars renewed that push and added the need for good performance over a really wide temperature range and to cram even more power into a tighter space and do it it without breaking the bank.
The market for really cheap cost per kwh batteries that last a really long time is only about 10 years old.
