Introduction to supercapacitors
Aug 13, 2018

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


As a high-power physical secondary power source, supercapacitors are widely used in various fields of the national economy. Supercapacitors can be used in a wide range of fields such as industrial electronics, transportation, transportation energy, renewable energy, power smart grid, and military. At the same time, the supercapacitor has both high discharge power and large charge storage capacity. As the performance of supercapacitors increases, it is expected to replace traditional batteries in some areas such as low-power electronics and new energy storage.


Supercapacitors can be combined into a supercapacitor module by increasing the capacity and voltage with corresponding series and parallel connection. The supercapacitor module not only has all the characteristics of the supercapacitor unit, but also has a status monitoring function, which is better. The maintenance is maintenance-free and easy to maintain. In summary, supercapacitors have a good development and application prospects.
