Electric double-layer capacitors (EDLCs), commonly known as supercapacitors, are advanced energy storage devices that bridge the gap between batteries and traditional capacitors. They offer exceptional features such as long lifespan, low cycle average cost, high charge/discharge rate, high output power, and enhanced safety, making them ideal for demanding applications.

Unlike aluminum electrolytic capacitors, EDLCs can be charged directly without load resistance, ensuring greater efficiency. These capacitors are widely utilized in electric devices, electric vehicles, internal combustion engines, military machinery, and other electromechanical systems, where reliable energy storage and quick power delivery are critical.
