Supercapacitors A supercapacitor, also known as an ultracapacitor or electric double-layer capacitor (EDLC), is an energy storage device that bridges the gap between conventional capacitors and batteries. Unlike batteries, which store energy chemically, supercapacitors store energy electrostatically.
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.
While traditional capacitors store energy through the separation of charge between two plates, supercapacitors leverage a larger surface area and thinner dielectrics, allowing for significantly higher capacitance and energy storage capabilities.
Our supercapacitors have been developed to meet the growing need for sustainable energy storage in wireless electronics. They offer the same benefits as conventional supercapacitors but with improved safety and a reduced environmental footprint – in a compact form factor.
Supercapacitors, also known as ultracapacitors and electric double layer capacitors (EDLC), are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.
Electric double layer capacitors, namely super-capacitors, are used mainly to assist other power supplies in coping with surge power requirements particularly in electric/hybrid vehicles. The Shanghai municipality tested electric buses powered by supercapacitors (capabuses).
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.
In supercapacitors, the electrical double layer formed next to a large-area electrode and an electrolyte is effectively used, and hence these devices are technically called electric double-layer capacitors (EDLCs). At this stage, it is worth summarizing the difference between electrochemical (EC) cells and electrochemical capacitors.
