During the development of supercapacitors for more than 30 years, miniature supercapacitors have been widely used in small mechanical equipment, such as computer memory systems, cameras, audio equipment and intermittent auxiliary equipment. Large scale cylindrical supercapacitors are mostly used for cars and natural power collection. As far as the development of the next decade is concerned, Farad capacitor It will be an important part of the transportation industry and natural power collection.

The low impedance of supercapacitors is essential for many high power applications today. For fast charging and discharging, the small ESR of the supercapacitor means greater power output, charging in a few seconds and discharging in a few minutes.

For example, electric tools, electric toys; In the UPS system, the super capacitor provides instantaneous power output as a supplement to the standby power supply of the engine or other uninterruptible systems; Low current, continuous discharge for a long time, such as computer memory backup power supply.

In the field of natural power collection, the operation process of wind power generation cannot be separated from the hydraulic system or batteries. Since each time the fan blades of the generator stop, the internal turbine will adjust the fan blades to the specified position. This process is called pitch control system in wind power generation. The electrical energy required in the operation process is supplied by the hydraulic system or batteries.

Power support when a public car switches from one power source to another; Instantaneous power pulse application, short-term power support of important storage and memory systems.

Large scale super capacitor (125 V) can be used in the braking system of trains and subways, and can also supply energy output for material handling engineering vehicles; Medium scale supercapacitor (75V) can be used for solar energy collection, because it can work at high temperatures; 48V supercapacitor is used in cars; The small-scale supercapacitor (within 2.7 V) has made great contributions to the continuous power supply of communication equipment and the backup power supply of computer memory system.
