EDLC (Electric Double-Layer Capacitor) capacitors are a type of capacitor that stores energy through the accumulation of electrical charge at the interface between an electrode and an electrolyte. Unlike traditional capacitors, which use a dielectric material to separate the plates, EDLC capacitors use a double-layer effect, where the electrolyte ions are adsorbed onto the surface of the electrode. This results in a high capacitance value, making EDLC capacitors suitable for applications requiring high energy storage and rapid charge/discharge cycles.

The electrodes in EDLC capacitors are typically made of activated carbon, which has a high surface area, allowing for a large number of ions to be adsorbed. The electrolyte can be either aqueous or organic, depending on the specific application and desired performance characteristics. Aqueous electrolytes are commonly used due to their lower cost and higher conductivity, while organic electrolytes offer higher voltage ratings and better stability.

EDLC capacitors are widely used in various applications, including renewable energy storage systems, electric vehicles, and consumer electronics. Their ability to handle a large number of charge/discharge cycles makes them an attractive option for applications requiring frequent and rapid energy storage and release. Additionally, EDLC capacitors have a long lifespan and can operate over a wide temperature range, making them a reliable choice for many industrial and consumer applications.
