4 FAQs about Sudan Super DC Capacitor

Are all supercapacitors EDLC?

Sometimes all supercapacitors are mis-called as EDLC (Electric Double Layer Capacitors), however EDLC is a one subset of supercapacitor family. Supercapacitors features sit between capacitors and batteries, with a firm cell rated voltage between 1 and 3.8V.

Do supercapacitors use a solid dielectric?

Unlike ordinary capacitors, supercapacitors do not use a conventional solid dielectric, but rather, they use electrostatic double-layer capacitance and electrochemical pseudocapacitance, both of which contribute to the total energy storage of the capacitor.

How is the capacitance of a supercapacitor determined?

The capacitance value of a supercapacitor is determined by two storage principles: Double-layer capacitance – electrostatic storage of the electrical energy achieved by separation of charge in a Helmholtz double layer at the interface between the surface of a conductor electrode and an electrolytic solution electrolyte.

How much energy does a CDC supercapacitor produce?

As of 2015, a CDC supercapacitor offered a specific energy of 10.1 Wh/kg, 3,500 F capacitance and over one million charge-discharge cycles. Graphene is a one-atom thick sheet of graphite, with atoms arranged in a regular hexagonal pattern, also called "nanocomposite paper".
