Supercapacitor
Hybrid capacitors combine the rapid charge/discharge kinetics of electric double-layer capacitors (EDLCs) with the high energy density of pseudocapacitive or battery-type electrodes.

Self-Discharge of Ultracapacitors
Ultracapacitors are also known as supercapacitors or EDLC (electric double-layer capacitors). These capacitors are available with capacitances in the farad range.
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

This also means that a fast discharge is not very practical: the capacity is greatly reduced. How fast, depends on efficiency/capacity requirements, and the type.
Super capacitor discharge calculator
This calculator determines timekeeping operation using a supercapacitor based upon starting and ending capacitor voltages, discharge current, and capacitor size.
The self-discharging of supercapacitors interpreted in terms of a
Supercapacitors are prone to self-discharging, which is most often measured as a voltage decrease with time under open circuit conditions. It is of substantial interest to find simple and
Self-Discharge of Ultracapacitors
Ultracapacitors are also known as supercapacitors or EDLC (electric double-layer capacitors). These capacitors are available with capacitances in the farad range. There are two classes of
Supercapacitor Leakage Current and Self Discharge Characteristics
Leakage current is a charge maintaining current while the supercapacitor is on charge. In order to calculate required backup time over system operating temperature range, designers need to take a
