Electric Double Layer Capacitors (EDLC)

Electric Double Layer Capacitors (EDLCs) are energy storage components that store electrical energy in an electric field formed between two electrodes of a given structure. These structures are characterized by having very large capacitance relative to conventional capacitors, and can be as large as thousands of Farads. EDLCs are also known as supercapacitors, supercap, electrical double-layer capacitors, electrochemical double-layer capacitors, ultracapacitors, and (electro) mechanical capacitors.

EDLCs are passive components commonly used in automotive and industrial applications for power conditioning, including power smoothing and battery replacement. EDLCs can also be used for DC/DC conversion, thus allowing voltage-independent operation of the load, power smoothing in energy storage applications, and can be configured for frequency-limited applications. Because of their large voltage scaleability and fast charging, EDLCs are ideal for grid integration, renewable energy storage, and various other applications that require large amounts of energy storage.

FA1A224ZF Application Field and Working Principle

The FA1A224ZF is a EDLC Supercapacitor that is rated for 2.7 to 2.8 Volts and features a very low leakage and long life. This supercapacitor has applications in engine starting, wireless devices, consumer electronics, and automotive engine management systems. As its low leakage current and long life makes it suitable for automotive systems such as hybrid electric vehicles, it is also suitable for industrial safety circuits.

The principle of operation of FA1A224ZF is simple. When a voltage is applied across two electrodes it results in the formation of a double layer of charges at each electrode interface. These charges create an electric field that stores energy due to the charge separation, and that energy stored in this field is then used to operate the circuit. Furthermore, these electrodes also facilitate the transportation of electrons, thus allowing the transfer of energy between the electrodes. This transfer of electrons can be accelerated by introducing additional substances that act as electron transport agents.

Supercapacitors

Supercapacitors are energy storage components that share many of the properties of both capacitors and batteries. They are particularly useful for energy storage applications, and are used where very rapid charging and discharging is required. Supercapacitors are available in both cylindrical and rectangular shapes, and operate in the range of 5-200 Volts or higher. They are also available in various sizes, with the largest having capacitance over 100,000 Farads.

Supercapacitors are composed of an electrolytic solution and two facing electrodes. As energy is transferred between the two electrodes, a double-layer of static charges build up at the electrode interface. These charges create an electric field that can store energy for as long as it maintains a given voltage. This energy is then used to power the circuit.

Supercapacitors also have several advantages compared to batteries. For example, supercapacitors are able to be charged and discharged at very high rates, which is not achievable by batteries, and are also much more efficient than batteries in terms of energy storage. Supercapacitors also have better cycling performance and are more resistant to abuse than traditional batteries.
