Electric Double Layer Capacitors (EDLC)

The XH414HG-II06E is a type of electric double layer capacitor (also known as EDLC or "supercapacitor") designed for industrial applications. EDLCs are highly efficient, low-cost energy-storage devices that can be used to provide short-term surge currents and act as an emergency backup power source in critical systems. Unlike conventional capacitors, EDLCs employ two distinct layers of electrostatic charge separated from each other with an extremely thin (1-2 nanometers) insulator called a "double layer."

The XH414HG-II06E is capable of operating over a wide temperature range, from -25°C to 85°C (-13°F to 185°F), and its "self-healing" dielectric allows it to heal minor abrasions, scratches, and other damage for greater reliability. It also has a long cycle life, up to 500,000 cycles at 0.1C rate, making it suitable for frequent cycles and long-term use.

Its features also include low ESR (equivalent series resistance), low internal impedance, high cyclic stability, and high power density. The XH414HG-II06E is ideal for applications such as electric vehicles, energy harvesting, renewable energy sources, and backup power.

Working Principle

The basic working principle behind EDLCs is the same as that of any other capacitor. An electric field is created when voltage is applied between a pair of electrodes (known as "plates"), and this electric field attracts charges to the electrodes.

However, EDLCs employ a special type of electrode that is made from activated carbon. This activated carbon provides an extremely large surface area, which allows them to store more energy than traditional capacitors. This is how EDLCs are able to provide higher currents and longer period of energy storage.

This large surface area also allows EDLCs to charge and discharge more quickly than other types of capacitors. This makes them ideal for applications such as providing quick bursts of energy to motors or supplying emergency power during power outages.

Supercapacitors

Supercapacitors, also known as ultracapacitors, are similar to EDLCs in that they are composed of two plates, but the materials used in their construction are different. Supercapacitors use a combination of activated carbon and metal oxides as their plate material, which provides them with a much higher capacitance than EDLCs. As a result, supercapacitors are able to store much larger amounts of energy than EDLCs and are often used as replacements for batteries in applications that require higher amounts of power.

Supercapacitors also have the advantage of being able to charge and discharge much faster than EDLCs, allowing for very high power output and rapid energy transfer. This makes them well-suited for applications such as regenerative braking in hybrid and electric vehicles, or peak power smoothing in microgrids.

Unlike EDLCs, however, supercapacitors are more expensive, and their cycle life is much shorter. This makes them less suitable for long-term energy storage applications, but they are still ideal for providing quick burst of power when needed.
