Electric Double Layer Capacitors (EDLC), more commonly known as supercapacitors, are a form of energy storage technology that lie between the characteristics of conventional capacitors and batteries. A PHV-5R4H505-3 is an EDLC specifically designed to provide high power levels, long cycle life expectancy, and superior performance to other energy storage components. This article will analyze their application fields, and explain the working principle behind them.

Application Field

Supercapacitors are primarily used in applications that require frequent and low-energy on/off cycles. The high power output and superior reliability make these devices ideal for energy storage applications, such as emergency switched circuits. These components are also popular for use in automotive applications, particularly in the start-Stop system of modern vehicles, where they are usually paired with a battery to provide extra power when needed.

In industrial and commercial applications, supercapacitors can be used as a filter in power factor correction circuits, and a buffer for uninterrupted power supply (UPS) systems. Their high energy density makes them suitable for use with wireless sensors, saving battery time or the cost of continually changing them, while their robust design ensures that they are reliable and efficient.

Supercapacitors are also ideal for renewable energy sources, such as photovoltaic systems, as they possess high charging and discharging capabilities. Their long life expectancy ensures that many years of optimal performance are achieved with minimal maintenance, making them a great option for energy storage and efficiency.

Working Principle

Electric double layer capacitors are composed of two plates separated by an electrolyte. When a voltage is applied to the plates, a double layer of charge forms, consisting of ions from the electrolyte trapped between the plate and the dielectric material. This creates an electric double layer between the two plates, thus providing a high capacitance for the device.

Supercapacitors use a porous carbon-based material for the electrodes, as it allows more surface area for the electrostatic double layer to form. This results in a higher energy density, as more charge can be stored in the device. Generally, supercapacitors with higher surface areas can store larger amounts of charge, and hence will have higher energy densities.

The energy discharge rate of supercapacitors is extremely high, as the principle of storing and releasing charge is similar to that of traditional capacitors. They are capable of delivering high bursts of power or large loads of current for short periods of time before needing to be recharged.

In addition to their outstanding performance, supercapacitors also offer a longer life expectancy than other energy storage components. This is due to the lack of corrosion of their electrodes, which is normally the cause of deterioration in other storage devices.

Conclusion

The PHV-5R4H505-3 is an electric double layer capacitor designed for high power output, long cycle life expectancy, and superior performance. It can be used in a variety of applications requiring frequent and low-energy on/off cycles. The working principle behind the component involves the creation of an electric double layer between the two electrodes, which results in a high capacitance and energy density. These devices also boast superior reliability and a long life expectancy, making them a great option for energy storage and efficiency.
