Supercapacitor Technology and its Applications in Some Countries

A supercapacitor is the advanced version of the regular capacitors. One of the functions of this device is to store electrical energy in an electric field. This article explains to you more about supercapacitor technology and its applications.


A supercapacitor has the same function as regular capacitors. It stores electrical energy in an electric field. The difference between a supercapacitor and a capacitor is on the parts. A supercapacitor is known as a high-capacity capacitor. This device has two electrodes that work with the help of the ion-permeable membrane and an electrolyte ionically. The ion-permeable membrane works as a separator, whereas the electrolyte ionically works as a connector. The double-layer effect that the supercapacitor has helps to store electric energy. Supercapacitors use two principles to store energy, which is electrostatic and electromechanical. Supercapacitors also maintain the voltage limits in 2.5 up to 2.7 volts and even up to 2.8 volts and more, but reduce the durability.

Applications of Supercapacitor 

Let’s continue the explanation about supercapacitor technology and its applications by reading this example. You have to understand that a supercapacitor is not a battery. You can use supercapacitors for a quick charge. The ideal charge time is less than 60 seconds. If the charge time is more than 60 seconds, you can use a battery. One of the most applications of supercapacitors is a hybrid battery. Hybrid batteries are combining supercapacitors and batteries. It gives a better option in which it stores more energy, along with better durability.

One of the railroads in North America known as LIRR or Long Island Rail Road also uses supercapacitors. This tool can compete against the flywheel. Japan also apply 4MW systems in commercial buildings. The function of this application is to reduce grid consumption. Another application in Japan is a backup generator during power outages. One of the benefits is that the generator achieves power while waiting for the switch-over stable.

Supercapacitors are ideal for electric powertrains, hybrid vehicles, and fuel cells. It is because the system helps to charge the tool faster even during braking and acceleration. The tool also maintains the temperature and is more durable. Regular tools or traditional batteries can’t do it without help from the supercapacitors.

Now, you understand supercapacitor technology and its applications in real life. Some industries such as the vehicle industry achieve a lot of benefits by combining supercapacitors and batteries. You will get a tool with a longer cycle life, high power, low resistance, easy to charge, and low-temperature.
