A supercapacitor, which is 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 and ...

This effect is made possible by the accumulation of energy in the supercapacitor through an electric double layer (EDL). The ability of any capacitor to store charge is determined by the area of ...

Capacitors are electrostatic devices that ... forming a charge layer just atoms away from each other – called an electric double layer or EDL. This results in the high capacitance of ...

Pseudocapacitors are a type of electrochemical energy storage device that combines the high energy density of batteries with the fast charge/discharge rates and long cycle life of capacitors ... and ...

Ultracapacitors store electrical energy through static charge separation in a double-layer of ... electrolyte form electric double layers of opposite polarity to the electrode's polarity. A ...
