Supercapacitors are mainly used in two types of energy storage markets: automobile and fixed energy storage markets dominated by lead-acid battery stations, and nickel lithium battery The dominant consumer electronics market. In the field of new energy vehicles, super capacitors can be used together with secondary batteries to store energy and protect batteries. Usually, supercapacitors are used together with lithium-ion batteries to form a power supply for electric vehicles with stable performance, energy conservation and environmental protection, which can be used in hybrid electric vehicles and pure electric vehicles.

Supercapacitors can be well used in these two markets and have made great progress in these two markets. Rapid technological progress and cost reduction will enable it to establish its fourth (or fifth) largest position in the energy storage device market. In mobile communication base stations, satellite communication systems and radio communication systems, large pulse discharge power is required, and the high power output characteristics of supercapacitors can meet the power requirements of these systems.

In addition to the characteristics of high specific power and fast charging speed, supercapacitors are also at least 100 times longer than chemical batteries in terms of cycle life. They can charge and discharge millions of times, which can greatly save money. Supercapacitors can also be used as starting devices in ventilation, air conditioning, water supply and drainage systems in the construction field. In addition, Farad capacitor It can also be used in power stations, converters and railway systems, including electromagnetic valve control system, distribution panel opening and closing, railway turnout control devices, etc.
