Electric Double Layer Capacitors (EDLC)

An Electric Double Layer Capacitor (EDLC), also known as supercapacitor, is a high-capacity capacitor that has high energy storage capacity compared to other types of capacitors. It is used for storing and releasing electric energy from a device, and it is usually connected with a battery or other energy sources. The main characteristics of the EDLC are its high energy density, high charge/discharge rate, long life cycle, and wide operating temperature range, which makes it suitable for a wide variety of applications.

DH-5R5D473T Application Field and Working Principle

The DH-5R5D473T is a 5.5V EDLC with a maximum capacity of 4700F and rated operating voltage of 5.5V. It is designed for high-power, high-current applications such as solar energy storage, backup power, or emergency power, and it can be used in hybrid electric vehicles and renewable energy systems.

The DH-5R5D473T uses a new type of porous graphene-based materials as its active material, which makes it more efficient in terms of energy storage than traditional capacitors. This material is capable of absorbing more ions, resulting in a higher capacitance, allowing the DH-5R5D473T to store more energy per unit mass than conventional EDLCs.

The working principle of the DH-5R5D473T is based on the principle of electric double layer charging. When a voltage is applied to the capacitor, an electric double layer is created between the two electrodes, enabling charge carriers of opposite polarity to accumulate in the vicinity of the electrodes, thus leading to the storage of energy in the form of electrostatic energy.

This energy can then be used to provide high peak current, due to the low internal resistance and low energy dissipation of the EDLC, making the DH-5R5D473T an ideal choice for applications such as peak power demand and high-current pulses.

Supercapacitors

Supercapacitors, also known as ultra-capacitors or electric double layer capacitors (EDLCs), are energy storage devices that use electrostatic forces to store energy. They are ideal for applications that require high power and high energy density, such as regenerative braking systems for hybrid and electric vehicles, backup power for industrial applications, and energy storage systems for renewable energy sources such as solar and wind power.

Supercapacitors have a much higher energy storage capacity than regular capacitors, with a typical capacitance in the range of 1 to 100 farads and a much lower internal resistance. This makes them ideal for applications that require high power output and/or high energy storage densities. Furthermore, they are capable of operating over a wide temperature range and have a much longer lifespan compared to traditional batteries.

Supercapacitors use a modified version of an electric double layer charging principle. The principle is based on the attraction between ions when an electric field is applied between two electrodes, causing the ions to be stored in region between the electrodes. As a result, the electric double layer is formed which allows for the storage of electrostatic energy.

The most common charging method used with supercapacitors is the constant current/constant voltage (CC/CV) charging technique, which is typically used with a voltage ranging from 2.7V to 10V, depending on the characteristics of the device. The CC/CV charging cycle allows for a fast charging process, making it ideal for applications that require a high power output and/or a high energy storage density.
