What's the use of supercapacitors?

Supercapacitor is a new type of energy storage device, which is mainly used as a backup power supply after the main power supply is cut off to provide short-term energy. Supercapacitors have the characteristics of high specific capacity and high specific power. The capacity density ranks first among all kinds of capacitors, and the power density can reach 10~ 100 times that of rechargeable batteries. So supercapacitors can make up the gap between batteries and traditional capacitors. In some fields, supercapacitors can replace batteries. At present, it is mostly used as a backup power supply in smart meters, water meters and gas meters. In addition, it is also widely used in smart home, industrial control panel, power distribution terminal equipment, automobile driving recorder, new energy electric vehicle, solar energy, wind energy and other fields.
