Electric Double Layer Capacitors (EDLC)

Electric Double Layer Capacitors (EDLC), also known as supercapacitors or ultracapacitors, are energy storage devices with a capacity to store energy up to tens of thousands of times higher than conventional capacitors. They are made up of two electrodes, with separator material between them, and use a layer of adsorbed charge to form an electric double layer, which gives it the ability to store and release energy rapidly and adjust its capacity depending on the power requirement. The HV0820-2R7305-R is a EDLC used in applications such as automotive, industrial, and telecom devices. It has very high capacitance and power density, and works at a wide range of temperatures from -40°C to +85°C. It also can be used in many high-load applications owing to its very low equivalent series resistance or ESR, along with excellent cyclic performance.

Working Principle

The operating principle of EDLC can be mainly attributed to electrostatic double-layer capacitance. This type of capacitance involves an interaction between an electrolyte solution and the surface of an electrode, seeking to achieve an equilibrium. It is a faradaic process in which ions from the electrolyte solution adsorb onto the surface of the electrodes and form a surface-adsorbed charge. This adsorbed charge forms a double-layer interface, creating an electric field that then can store or discharge energy quickly as needed. EDLCs have two key components, namely the activated carbon electrode and the electrolyte/separator material. The activated carbon electrodes are usually made of shredded activated carbon particles and are tremendously high conductive. This carbon provides an extremely large surface area of obtainable charge, giving the EDLCs their ability to hold a great amount of charge. The separator material, used between the two electrodes, is mainly responsible for providing insulation between them.The HV0820-2R7305-R has an electrolyte/separator material between its two electrodes made up of a polymer, enabling it to work even at very high temperatures. It also has an having extremely low equivalent series resistance or ESR, and is hence suitable for many applications requiring high current rates and quick response time. It also has good reliability and good cycle life, making it ideal for applications that need sustained power up to tens of kHz.

Application Field

The HV0820-2R7305-R is used in many applications and industries, such as automotive, industrial, and telecom. In automotive, it is used to balance hybrid engine performance. It is also used in electric vehicles, to store the energy generated from regenerative braking and to provide immediate power boost or acceleration when necessary. Additionally, it is also used to combine with a fuel cell to store energy from the regenerative brake. In industrial applications, its large capacitance makes it excellent for power delivery in applications which have strict peak power and response time needs. It is also used in off-grid solar energy storage and wind energy storage, as a short-term storage for surplus energy, which can then be used later when there is a need. In telecom applications, the HV0820-2R7305-R supports high-power load requirements by providing high capacitance, low ESR and great cycle life. It\'s also used in telecommunications for power backup and long-term site power requirements.Overall, the HV0820-2R7305-R is extremely reliable and dependable for some of the most high-load applications out there. With its large capacitance and very low equivalent series resistance, it is an ideal choice for energy storage applications requiring quick response time without compromising on performance.
