Analysis of the market status and development prospects of the supercapacitor industry

Supercapacitors are novel devices that store energy through an interfacial double layer formed between electrodes and electrolytes. When the electrode is in contact with the electrolyte, due to the action of Coulomb force, intermolecular force and interatomic force, a stable double-layer charge with opposite sign appears at the solid-liquid interface, which is called the interface double layer. Think of an electric double-layersupercapacitoras 2 inactive porous plates suspended in an electrolyte, and a voltage is applied to the 2 plates. The potential applied to the positive plate attracts the negative ions in the electrolyte, and the negative plate attracts the positive ions, thus forming anelectric double layer capacitor. Electric double layercapacitorscan be divided into carbon electrodedouble layer supercapacitors, metal oxide electrode supercapacitors and organic polymer electrode supercapacitors according to different electrode materials. Supercapacitor refers to a new type of energy storage device between traditional capacitors and rechargeable batteries. It not only has the characteristics of fast charging and discharging of capacitors, but also has the energy storage characteristics of batteries.

Supercapacitor is a new type of electrical energy storage device between traditional capacitors and batteries. Its mechanism is physical energy storage. The device does not generate heat. It has the advantages of high power, long life and good safety. It is irreplaceable in many application fields. . Its application fields mainly include backup power supply, replacement power supply or main power supply for low-power electronic equipment; electric vehicle and hybrid vehicle power supply; renewable energy power generation and energy storage, instantaneous power compensation; variable frequency drive system energy buffer; military equipment, etc.

Affected by the new energy vehicle subsidy policy, the new energy vehicles produced by CRRC for domestic customers are mainly equipped with lithium batteries, but from the perspective of the entire life cycle, the future development potential of supercapacitors is unlimited.

Supercapacitors have the advantages of fast charging, high power, long cycle life, strong temperature adaptability, environmental protection and no pollution. With the further development of the application market, supercapacitors will become an important member of the energy storage family. At present, there are more than 20 core supercapacitor enterprises in my country. It is estimated that by 2020, the size of my country's supercapacitor market will be about 13.84 billion yuan.
