What Are Supercapacitors?CharacteristicsConstruction and Properties of SupercapacitorsApplications For SupercapacitorsSupercapacitors are electronic devices which are used to store extremely large amounts of electrical charge. They are also known as double-layer capacitors or ultracapacitors. Instead of using a conventional dielectric, supercapacitors use two mechanisms to store electrical energy: double-layer capacitance and pseudocapacitance.
