Supercapacitor | Capacitor Types | Capacitor Guide
Supercapacitors are electronic devices which are used to store extremely large amounts of electrical charge. They are also known as double-layer capacitors or ultracapacitors. Instead of using a conventional dielectric, supercapacitors use two mechanisms to store electrical energy: double-layer capacitance and pseudocapacitance.

Supercapacitor vs Battery
Here are some disadvantages of supercapacitors: Self-discharge rate. Supercapacitors aren''t well-suited for long-term energy storage. The discharge rate of supercapacitors is significantly higher than lithium-ion batteries; they can lose as much as 10-20 percent of their charge per day due to self-discharge. Gradual voltage loss.

How do supercapacitors work?
Batteries and capacitors do a similar job—storing electricity—but in completely different ways. Batteries have two electrical terminals (electrodes) separated by a chemical substance called an electrolyte. When you switch on the power, chemical reactions happen involving both the electrodes and the electrolyte.
