Double Layer Capacitors are a type of electrolytic capacitors which have high storage density. This enables them to have a high capacitance value. The capacitance value of a double layer capacitor is of the order of Farads in comparison to normal capacitors which have micro farads and nano farads.
These capacitors have high rage of charging and discharging. Double layer capacitors are also known as Supercapacitors or Ultra capacitors.
Double Layer Capacitors are used in a wide range of applications the Electric Automobile industry and in solar panels.
