Introduction to Supercapacitors

Supercapacitors are a new type of energy storage device that has only been mass-produced in recent years, also known as electrochemical capacitors. Compared with conventional capacitors, it has the advantages of high power density and high energy density of ordinary batteries, as well as short charging and discharging time, good cycling performance, long service life, wide temperature range, flexible capacity configuration, maintenance free and green environmental protection. Therefore, supercapacitors have the dual functions of traditional capacitors and batteries, filling the gap between the two traditional technologies and thus having great potential for development.

 

Supercapacitors, as high-power physical secondary power sources, have a wide range of applications in various fields of the national economy. Supercapacitors can be applied in a wide range of fields such as industrial electronics, transportation, transportation energy, renewable energy, smart grids, and military industry. At the same time, supercapacitors have the advantages of high discharge power and large charge storage capacity. With the improvement of supercapacitor performance, it is expected to replace traditional batteries in some fields such as low-power electronic devices and new energy storage.

 

Supercapacitors can increase their capacity and improve their withstand voltage through corresponding series and parallel connections, thus forming a supercapacitor module. The supercapacitor module not only possesses all the characteristics of a supercapacitor unit, but also has status monitoring function, which can better achieve maintenance free and easy maintenance. In summary, supercapacitors have great prospects for development and application.
