EEC-F5R5U224A

Electric double-layer capacitors (EDLCs), also referred to as supercapacitors, are energy storage devices that bridge the gap between conventional electrolytic capacitors and battery technologies. They have recently been extensively studied due to their potential to offer rapid dynamic behavior, lightweight compactness, high power density, higher longevity, and improved safety over conventional batteries. One example of an EDLC is the EEC-F5R5U224A supercapacitor. Its application field and working principle will be discussed in the following article.

Application Field of EEC-F5R5U224A Supercapacitor

The EEC-F5R5U224A supercapacitor is an electric double-layer capacitor (EDLC) developed for applications where very high energy storage and delivery density are required. It can store up to 1,000Farad which makes it ideal for high power density drive and energy storage applications in automobiles and motorsport applications.The capacitor is capable of delivering up to 3A pulse current, which makes it suitable for applications such as starting battery boosting, sump pumps, emergency lighting, and tachometers. The EEC-F5R5U224A is also ideal for applications in solar converters, LED drivers, security systems, and emergency signaling devices. Additionally, the supercapacitor can be used to replace the conventional electrolytic capacitor in many traditional electronic applications such as audio equipment, sensors, digital clocks and watches, and medical applications.

Working Principle of EEC-F5R5U224A Supercapacitor

The working principle of the EEC-F5R5U224A supercapacitor is based on electrostatic double-layer capacitor (EDLC) construction. EDLCs work on the principle that when two electrodes are placed into an electrolyte solution, an electrical double-layer (EDL) will form on the two surfaces. This layer is composed of two layers of ions; an anion layer that is attracted to the positive electrode and a cation layer which is attracted to the negative electrode.The EEC-F5R5U224A supercapacitor utilizes this EDL to store electrical charges. The capacitor is composed of two electrodes (carbon and polymer) which are separated by a very thin porous separator layer, creating a pseudocapacitance. This pseudocapacitance is responsible for the higher energy density of the EEC-F5R5U224A compared to traditional electrolytic capacitors.Upon the application of a voltage, ions in the electrolyte are attracted to the electrodes. The high oxygen content of the electrode creates a very high charge density, which in turn increases the capacitance and allows for higher energy storage capabilities. This supercapacitor also has a very low ESR, meaning it can be charged and discharged very quickly, making it ideal for high power density applications.

Conclusion

The EEC-F5R5U224A is a type of electric double-layer capacitor (EDLC) developed for applications which require the highest energy density and delivery. It is capable of storing up to 1,000Farads and delivering up to 3A pulses, making it suitable for applications such as sump pumps, solar converters, LED drivers, security systems, and emergency signaling devices. The EEC-F5R5U224A utilizes a pseudocapacitance enhanced by its high oxygen content electrodes to increase its energy storage capabilities. Thanks to its high energy density and low ESR, the EEC-F5R5U224A is ideal for high-power applications.
