EDLC (Electric Double-Layer Capacitor) is a device known as an electric energy storage capacitor.

Due to its very high electrical capacitance, EDLCs can charge and discharge large amounts of electrical energy rapidly.

This enables rapid energy delivery and acceptance, making them particularly useful in high-power applications and energy regeneration fields.

Additionally, EDLCs can undergo numerous charge-discharge cycles, have a long lifespan, and operate with high efficiency.

Due to these characteristics, EDLCs are commonly referred to as supercapacitors or ultracapacitors.
