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.What is a double layer capacitor?When a suitable liquid and solid are used, and a voltage is applied, two layers of opposite polarity are formed, hence the “double layer.” KEMET’s electrical double layer capacitor, also known as a “supercapacitor,” uses activated carbon as its solid part and an aqueous solution of dilute sulfuric acid as its liquid part.
How is a supercapacitor different from a regular capacitor?The supercapacitor, also known as ultracapacitor or double-layer capacitor, differs from a regular capacitor in that it has very high capacitance. A capacitor stores energy by means of a static charge as opposed to an electrochemical reaction. Applying a voltage differential on the positive and negative plates charges the capacitor.
