Electric Double Layer Capacitors (EDLC)

Electric double layer capacitors, also known as EDLCs or supercapacitors, are a type of capacitor that use an electric double layer of ions stored at a dielectric material surface to store energy. The unique feature of EDLCs is that they can store much more energy than ordinary capacitors, but with a much smaller form factor, making them ideal for a wide array of applications.One of the most popular types of EDLCs is the DGH205Q2R7. This particular supercapacitor is a 2.7V, 5.5F device that is designed for high performance and long life. It has a wide operating temperature range, from -40°C to +85°C, and is ideal for automotive applications due to its high safety, reliability and stability.The applications for the DGH205Q2R7 are diverse and range from automotive to industrial usage. It is used as an ignition source in electric vehicles, solar power plants and inverter systems. As part of hybrid energy storage systems, it also provides extra power for microgrids and distributed generating systems.In addition, the DGH205Q2R7 is used in portable electronics, medical devices, consumer electronics and other fields. Due to its combination of performance, small size and safety, it is suitable for many different types of electronics applications.

Working Principle

The working principle of the DGH205Q2R7 is based on electric double layer capacitance. This is achieved by storing charge on the surface of an activated material, usually composed of carbon nanotubes or graphene.At the core of the DGH205Q2R7 is two different layers of ionic charge, a negative layer and a positive layer. In between these layers is a dielectric material, which acts as a barrier that prevents the charge from leaking away. When an electric field is applied from an outside source, the ions are attracted to the negative and positive charged layers and stored within the dielectric material.This allows the capacitor to hold a large charge relative to its size. The total capacitance of the capacitor is determined by the ratio of the surface area of the activated material and the thickness of the dielectric material. The higher this ratio, the higher the capacitance of the capacitor.The DGH205Q2R7 is one of the most efficient EDLCs, due to its high surface area to dielectric thickness ratio. This allows it to store more energy than other EDLCs and gives it a long life span. It also has a wide operating temperature range and excellent safety features which make it ideal for many different types of applications.
