Electric Double Layer Capacitors (EDLC) and Supercapacitors are two varieties of electrode technologies with slightly different applications and operating principles.

The common denominator between them is the storage of electrical energy using an electric field. This is the most prevalent characteristic that divides EDLC and Supercapacitors from conventional capacitors.

Electric Double Layer Capacitors (EDLC) are commonly referred to as “supercapacitors” and are used for high power, low frequency applications. They are typically used for peak power applications, where the capacitors store and release short bursts of energy. EDLCs store electricity in an "electric double layer", a thin film of charges. This double layer develops when a liquid electrolyte is placed between two electrodes, causing an adsorption of charge in the form of ions onto the electrodes. The charge storage capability of this electric double layer is much higher than that of a single conventional capacitor.

Unlike EDLCs, Supercapacitors are used for low power, high frequency applications. They are typically employed as an alternate source of energy storage in place of conventional batteries for applications such as UPS, EV/HEV and renewable energy. Unlike EDLCs, which store energy using an electric field, Supercapacitors store energy using ion storage in an electrolyte solution. As a result, their charge and discharge rates are significantly faster than EDLCs.

MAL219622474E3 is a large electric double layer capacitor that is designed for peak power storage and can provide high currents. It can be used in applications such as automotive starter/stop systems, vehicle propulsion, and energy regeneration systems, and it can also act as a replacement for batteries. The capacitor has a double layer structure, in which electrodes are separated by a thin layer of liquid electrolyte. When an electrical current is applied to the electrolyte, an electric double layer is formed, which stores electrical energy. The capacitor can hold two times its rated capacitance with a voltage rating of up to 65 volts. MAL219622474E3 has a very low equivalent series resistance (ESR), which allows for high currents to be drawn until almost all of the stored energy is released.

Both EDLC and Supercapacitors are heavily utilized in modern electronics, each with its own strengths and weaknesses. EDLCs, such as the MAL219622474E3, are suitable for peak power applications, while Supercapacitors are better suited for low power applications. This is due to their respective operating principles. While both technologies are capable of storing and releasing electrical energy, they use different mechanisms to do so. EDLCs rely on an electric double layer, while Supercapacitors rely on ion storage in an electrolyte solution.
