How do supercapacitors work?
Capacitors use static electricity (electrostatics) rather than chemistry to store energy. Inside a capacitor, there are two conducting metal plates with an insulating material called a dielectric in between them—it''s a dielectric sandwich, if you prefer! Charging a capacitor is a bit like rubbing a balloon on your jumper to make it stick.

2. A general answer which is not of any particular use is that electrical energy, and the forms in which we store it, are typically very low entropy systems. The lower the entropy the more they "want" to dissipate and the harder it is to stop that tendency to turn into (ultimately) heat.
8.4: Energy Stored in a Capacitor
The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.
Energy of a capacitor (video) | Khan Academy
