How do supercapacitors work?

What is a supercapacitor? A supercapacitor (or ultracapacitor) differs from an ordinary capacitor in two important ways: its plates effectively have a much bigger area and the distance between them is much smaller, because the separator between them works in a different way to a conventional dielectric. Although the words "supercapacitor" and "ultracapacitor" are …
