There is no chemical reaction or mechanical movement such as high-speed rotation during the use of supercapacitors; there is no pollution to the environment and no noise; its simple structure and small size make it an ideal energy storage device.

2 days leakage of 50%, the equivalent volume capacity is only 10% of the lithium battery, which can only be used for occasions requiring instantaneous impact power. Farad capacitors are capacitors, which are an order of magnitude worse than batteries. Capacitors are destined to be a temporary storage of electricity. But it's super explosive. Therefore, the bus can run for 2 kilometers, and the small size can explode powerful power. Just can't last.

Farad capacitors are different from traditional chemical power sources. They are power sources with special properties between traditional capacitors and batteries. They mainly rely on electric double layers and oxidative recovery pseudocapacitors to store electrical energy. However, there is no chemical reaction during its energy storage process. This energy storage process is reversible, and it is precisely because of this that the supercapacitor can be repeatedly charged and discharged hundreds of thousands of times.

Electric double-layer supercapacitors are two inactive porous plates suspended in an electrolyte to which a voltage is applied. The potential applied to the positive plate attracts the negative ions in the electrolyte, and the negative plate attracts the positive ions, thus forming an electric double layer capacitor on the surface of the two electrodes.

The structure of supercapacitor is composed of porous electrode material with high specific surface area, current collector, porous battery separator and electrolyte. The electrode material and the current collector should be closely connected to reduce the contact resistance; the gap between the supercapacitor manufacturers should meet the conditions of having the highest ionic conductance and the lowest electronic conductance as possible, and the supercapacitor module is generally a fiber structure. Electronic insulating materials, such as polypropylene film. The type of electrolyte is selected according to the nature of the electrode material.

The advantages are high power density, short charge and discharge time, long cycle life, and wide operating temperature range.
