> The energy density rating of the average supercapacitor is between 2,500 Wh per kg and 45,000 Wh per kg. That's from your source, and those numbers are entirely made up. The Wikipedia article for supercapacitors lists a more normal 1.5 Wh/kg to 260 Wh/kg (with only one research nanomaterial going above 15 Wh/kg). No commercial supercapacitor has a higher energy density than a standard lithium ion battery. Edit: The absurdly fast charging speeds would make for some fun pit stops, though
