A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries.
A Power Capacitor is an electrical device that can store and discharge electric energy. The device consists of one or more pairs of plates, separated by an insulating material (the dielectric), which are attached to two terminals that allow the stored energy to be discharged into a circuit when required. The power capacitor symbol is shown below.
In this context, the super capacitors, as an energy storage technology, possesses excellent performances such as high power density, maintenance-free, and long life, and it have become the focus of attention in academia and industry. This section mainly will introduce the electrochemical mechanism of supercapacitors.
Electrochemical double layer capacitors, also known as supercapacitors or ultracapacitors, are energy storage elements with high energy density compared to conventional capacitors and high power density compared to batteries.
In the energy-power spectrum, supercapacitors take an intermediate place between batteries and dielectric capacitors, delivering higher power densities than the former and higher energy densities than the latter .
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.
