How do supercapacitors work?
In an ordinary capacitor, the plates are separated by a relatively thick dielectric made from something like mica (a ceramic), a thin plastic film, or even simply air (in something like a capacitor that acts as the tuning dial inside a radio). When the capacitor is charged, positive charges form on one plate and negative charges on the …
