Electric Double Layer Capacitors (EDLC)

An electric double layer capacitor (EDLC), also ELC, or sometimes also known as supercapacitor, ultracapacitor or goldcap, is an electrical device that stores energy in a double layer of charge. It is essentially a form of electrochemical capacitor that works on the same principle as a traditional electric capacitor, with two surfaces separated by an insulating material. The difference between the two is that instead of using a porous material as the dielectric, EDLCs use two thin layers of metal oxide separated by a thin layer of electrolyte. The metal oxide layers host the electrochemical charges, drawing in opposite charge particles. The opposing charges generate an electric field, which can be used to store energy, allowing for fast charging and discharging.

One major advantage of EDLCs is their extremely high capacitance, which is up to several orders of magnitude higher than that of a conventional electric capacitor. This makes them ideal for applications such as energy harvesting, renewable energy storage, and peak power management. EDLCs are also very low-profile and have the ability to withstand a wide range of temperatures and high temperatures, making them suitable for a variety of extreme environment applications.

DB-5R5D474T Application Field and Working Principle

DB-5R5D474T is a cylindrical electric double layer capacitor (EDLC) with a high-performance anode material, 400F (2.7V voltage nominal) at 105°C with low resistance. It has features including ultra-thin dielectric layers, very low ESL/ESR, and low profile. It is suitable for high power peak demands and longlife energy storage.

The working principle of DB-5R5D474T is based on colloidal ions being adsorbed to the electrodes surface. This creates an electric double layer (EDL) structure between the electrodes, enabling them to store energy. The two layers of ions are separated by a very thin dielectric layer which is what allows the device to store and release energy at a very high rate.

DB-5R5D474T can be applied in many fields including renewable energy storage, peak power management, UPS systems and solar pumps. It has the widest temperature range (-40℃ to 105℃) and the highest number of recharge cycles than any other type of EDLC. Its extremely high capacitance and energy storage efficiency make it a great choice for applications that require reliable energy storage.

Supercapacitors

A supercapacitor, also known as an electrochemical capacitor, is a device that stores energy by using an electrochemical double-layer of ions on the surface of two metal plates. A supercapacitor is a type of capacitor with very high capacitance that can store substantial amounts of energy for a very short time period. The energy is stored as an electrostatic charge in the double-layer which forms between the two plates.

Supercapacitors are used in a wide range of industrial, automotive, and consumer applications. They are particularly popular for energy storage applications such as regenerative braking systems, uninterruptible power supplies, and power tools. Supercapacitors can offer a much longer cycle life than traditional chemical batteries, making them an ideal choice for such applications. They also offer higher peak power capability, making them suitable for peak power management applications.
