Why can supercapacitors store energy

capacitors (supercapacitors) consist of two electrodes separated by an ion-permeable membrane (), and an electrolyte ionically connecting both electrodes. When the electrodes are polarized by an applied voltage, ions in the electrolyte form electric double layers of opposite polarity to the electrode's polarity. For example, positively polarized electrode. Supercapacitors use dielectric or insulator between their plates to separate the collection of positive (+ve) and negative (-ve) charges building on each side’s plates. It is this separation that allows the device to store energy and quickly release it. It basically captures static electricity for future use. [pdf]

FAQS about Why can supercapacitors store energy

How do supercapacitors store more energy?

Read more in our article on capacitors. Bottom: Supercapacitors store more energy than ordinary capacitors by creating a very thin, "double layer" of charge between two plates, which are made from porous, typically carbon-based materials soaked in an electrolyte.
