Knowing the fundamentals of supercapacitors is a prerequisite for comprehending the subject matter of Energy storage. A supercapacitor is a high-capacitance capacitor that has been engineered for specific use.
The EDLC-type supercapacitor is well-known for having a high-power density but low energy density. This is one of the disadvantages of its applicability for a wide range of devices.
The amount of energy storage in a supercapacitor is 5-10 times less than the batteries because of a different method of charge storage. That’s why supercapacitors have low energy density.
