principle

The supercapacitors can be developed according to the theory of electrochemical dual -electrocompany, which can provide powerful pulse power. When charging, it is on the electrode surface of the ideal polarization state. The charge will attract the heterosexual ions in the peripheral electrolyte solution, which will attach it to the electrode surface and form formed The dual charge layer constitutes a dual -electrocomputer capacitor. The charge storage of the supercapacitors occurs on the dual electrode layer formed by the electrode/electrolyte, as well as the migration of the charges generated by the electrode on the surface of the electrode, the electrochemical adsorption, the aid, and the oxidation reduction.

Application characteristics

Compared with traditional capacitors and secondary batteries, the ratio of supercapacitors is more than 10 times the battery. The ability to store charge is higher than that of ordinary capacitors, and it has fast charging speed, no pollution to the environment, long cycle life, and use. The characteristics of the temperature limit range are wide.

However, the price of supercapacitors is more expensive. In the power system, it is mostly used for short -term, high -power load smoothing and peak power occasions, such as the launching support of high -power DC motors. The supercapacitors are incorporated on the side of the wind power system DC bus, which can not only store energy like a battery, but also the energy fluctuations caused by wind fluctuations, but also can also regulate the powerlessness. In addition, supercapacitors are also used as new energy storage devices for electric vehicles.
