Electric Double Layer Capacitors (EDLC)

Electric double layer capacitors (EDLC) are a class of energy storage device that stores energy in the form of an electrostatic charge. They are also known as \'supercapacitors\', \'ultracapacitors\', \'supercaps\', or \'ultra-capacitors\'. These capacitors have extremely high capacitance values compared to other types of capacitors and can store large amounts of energy in very small spaces. They are primarily used in applications that require rapid charging and discharging of energy, such as electric vehicles and grid storage.

Working Principle

The operation of an EDLC is based on the concept of \'double-layer capacitance\', which occurs when a layer of ions is formed at the interface between the two electrodes. This layer of ions acts as a medium through which the voltage passes, creating an electrostatic charge. The capacitance of the EDLC is determined by the thickness of this layer, which in turn is determined by the size and concentration of the ions present. This layer can be recharged by applying a voltage across the electrodes - when the voltage is removed the stored energy is released.

The high capacitance of EDLCs is due to the large surface area of the electrodes, which increases the amount of charge that can be stored. They also have a very low equivalent series resistance (ESR). This allows them to deliver high peak currents for short periods of time, making them ideal for applications that require rapid power delivery such as electric vehicles.
