Would it be possible to have some sort of hierarchy of "batteries" in an EV? A supercapacitor that charges in 1 minute and gives you 10 miles of range, a lower density fast charging battery that charges in 10 minutes and gives you 100 miles, and an ultra dense slow charging battery that needs hours but gives full range?
