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. Supercapacitors can be well used in these two markets and have made great progress in these two markets. The rapid progress of technology and the reduction of cost will enable it to establish its own four (or five) positions in the energy storage device market. Farad capacitor The traditional energy storage device of the scheme is difficult to quickly respond to the transient fluctuations of this power. By adding super capacitor banks, technical problems can be solved smoothly.

The supercapacitor can be used as the auxiliary power supply of the diesel engine starting system on the aircraft, which can provide the large impact current required by the aircraft engine at the moment. In addition, it can also solve the problem of insufficient power at the moment when 422 series power cars start the aircraft, so that it can protect the DC power car power generation system, especially the internal combustion engine, at the moment of starting. Super capacitor module Some mature battery technologies, such as lithium ion battery, nickel hydrogen battery and lead acid battery, have been developed. Because of the chemical reaction during the charging and discharging process, its development is limited. Therefore, the improvement of battery performance mainly depends on the improvement of packaging technology and the strengthening of preparation process.

Supercapacitor technology is still in its infancy and has high development potential. Compared with chemical batteries limited by the fixed structure of batteries, supercapacitors mainly rely on the physical properties of materials for energy storage. At the same time, compared with other mainstream batteries, supercapacitors still do not make full use of the potential of surface energy storage, and do not get rid of the "workshop" manufacturing mode and the shortage of raw material supply.
