Supercapacitors with capacitance levels of one Farad or more are now becoming more common than we imagine.
These supercapacitors are generally used to replace a battery, for example in systems where it is necessary to continuously feed a memory to save data.
These capacitors are made with a thin electrolyte separator that is flanked with activated carbon ions.
They are too large to use in most circuits and their frequency response is very limited
The capacitance value of a supercapacitor is very high and is in the order of milli farads with voltage ranges from 2V to 5V.
Supercapacitors are classified into three types based on their electrode.
