Dielectric capacitors are the ideal energy storage devices because they have excellent power density, high working voltages, and a long lifespan. With its lower size and better energy storage density, film capacitors make them simpler to incorporate into circuits than traditional dielectric capacitor devices.
In contrast to ceramic, film, and electrolytic capacitors, supercapacitors (also known as electrical double-layer capacitors (EDLC) or ultracapacitors) do not have a conventional dielectric. The capacitance value of an electrochemical capacitor is determined by two high-capacity storage principles. These principles are:
