Product Details

Supercapacitor is a new type of energy storage device between traditional capacitor and rechargeable battery. It has the characteristics of quick charge and discharge of capacitor and energy storage characteristics of battery.

Supercapacitor is a new type of device which stores energy through the interface between electrode and electrolyte. When the electrode contacts with the electrolyte, due to the action of Coulomb force, intermolecular force and atomic force, the solid-liquid interface appears stable and sign opposite double-layer charge, which is called interface double-layer. The electric double-layer supercapacitor is regarded as two inactive porous plates suspended in the electrolyte, and the voltage is applied to the two plates. The potential added to the positive plate attracts the negative ions in the electrolyte, and the negative plate attracts the positive ions, thus forming a double-layer capacitor on the surface of the two electrodes. According to different electrode materials, electric double-layer capacitors can be divided into carbon electrode double-layer super capacitor, metal oxide electrode super capacitor and organic polymer electrode super capacitor.

Compared with battery and traditional physical capacitor, the characteristics of super capacitor are mainly reflected in the following aspects:

(1) High power density. It can reach 102 ~ 104 kW / kg, which is much higher than the power density level of battery.

(2) Long cycle life. After a few seconds of high-speed deep charge discharge cycles of 500 000 to 1 million times, the characteristics of supercapacitors change little, and the capacity and internal resistance only decrease by 10% - 20%.

(3) Working temperature limit. Because the adsorption and desorption rates of ions in supercapacitor change little at low temperature, the capacity change of supercapacitor is much less than that of battery. The operating temperature range of commercial supercapacitors can reach - 40 ℃ to + 80 ℃.

(4) Maintenance free. Supercapacitor has high efficiency of charge and discharge. It can withstand overcharge and over discharge. It can charge and discharge stably. In theory, it does not need maintenance.

(5) Green environmental protection. Supercapacitor does not use heavy metals and other harmful chemicals in the production process, and has a long life, so it is a new type of green power supply.
