Electric Double Layer Capacitors (EDLC) and Supercapacitors ​​Application field and Working Principle

Electric Double Layer Capacitors (EDLC) have been developed as an alternative to rechargeable batteries for use in various applications, such as vehicle accessories, small appliances, and electronic equipment. EDLCs store an electrical charge in the form of an electric double layer, which can be rapidly discharged and recharged with extremely low leakage current. This feature allows EDLCs to provide high power output with excellent energy storage efficiency.Supercapacitors, also known as ultracapacitors, are electrochemical devices that can store and quickly discharge large amounts of energy. They are composed of two electrodes separated by an electrolyte, with each electrode carrying an electric charge. Supercapacitors can store and rapidly discharge very large amounts of energy, making them well suited for applications where rapid and frequent discharges or recharge cycles are required.

Working Principle

EDLCs and Supercapacitors use the same principle, but the latter uses additional capacitors to perform their function. Both technologies are based on the principle of Electric Double Layer Capacitance (EDLC): two metal electrodes are immersed in a liquid electrolyte that contains highly mobile electron donors and acceptors, resulting in an accumulation of charge on each of the electrodes. This results in an electric field between the two electrodes that acts as a capacitor.

Application Fields of EDLC and Supercapacitors

EDLCs and Supercapacitors can be used in a variety of applications, such as consumer electronics, medical equipment, automotive systems, military electronics, renewable energy systems, and industrial processes. They are also used in applications such as energy harvesting, energy transmission, ultra-fast charging, ultra-rapid discharging, and energy storage.To empower these applications, EDLCs and Supercapacitors offer a broad variety of benefits, such as high power density, longer life cycle, long shelf life, wide operating temperature range, high current pulse capability, high charge-discharge efficiency, fast charging & discharging time, and minimum leakage current. Moreover, they are known for their low environmental impact, which makes them suitable for green and sustainable energy storage systems.As such, EDLCs and supercapacitors have been gaining increasing attention in a wide range of applications due to their high power density, long life cycle, wide operating temperature range, and fast charging & discharging time. They are ideal for applications that require fast charging and discharging of energy, as well as those that require stable power output. Furthermore, their low environmental impact makes them an attractive choice for green and sustainable energy storage systems.
