Supercapacitor

OverviewDesignBackgroundHistoryStylesTypesMaterialsElectrical parameters

Electrochemical capacitors (supercapacitors) consist of two electrodes separated by an ion-permeable membrane (separator), 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 electrodes will have a layer of negative ions at the
