That, and it’d be a way to make electric cars viable. For with a supercapacitor, the car can be ‘refueled’ in less time than it’d take to refill your gas tank.
Which would then allow for long-distance travel.

“For with a supercapacitor, the car can be ‘refueled’ in less time than it’d take to refill your gas tank.”
Let’s say your electric supercapacitor car takes 15,000 Watts to run at some nominal speed. Now run it for four hours, that’s 60 Kilowatt-Hours.
If you were to recharge that capacitor in one second, the power required would be 216 megaWatts.
If it’s a 12 Volt system, you’d need to run 18 million Amperes.
There are practical limits to how fast you can charge a capacitor.
