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.
