A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit mass or energy per unit volume than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles
These capacitors offer very large capacitances in smaller form factor but have several pitfalls like they have minimum voltage requirement. Like li-ion batteries there should
EDLC supercapacitors offer high power density, allowing them to deliver quick bursts of energy. This characteristic makes them ideal for applications requiring rapid charge

(y) Electrolytic capacitors feature nearly unlimited charge/discharge cycles, high dielectric strength (up to 550 V) and good frequency response as alternating current (AC) reactance in the lower frequency range. Supercapacitors can store 10 to 100 times more energy than electrolytic capacitors, but they do not support AC applications.
Asymmetric supercapacitors (ASC) have shown a great potential candidate for high-performance supercapacitor due to their wide operating potential which can remarkably enhance the capacitive behavior.
Class 1: offers high stability and low losses for resonant circuit applications (NP0, P100, N33, N75, etc.). Class 2: offers high volumetric efficiency for buffer, bypass, and coupling applications (X7R, X5R, Y5V, Z5U, etc.). Class 1 ceramic capacitors offer the highest stability and lowest losses.
Supercapacitors occupy the gap between high power/low energy electrolytic capacitors and low power/high energy rechargeable batteries. The energy W max (expressed in Joule) that can be stored in a capacitor is given by the formula This formula describes the amount of energy stored and is often used to describe new research successes.
