Common farad capacitor

Product introduction:        

       The common Farad capacitor is a new type of energy storage device between the traditional capacitor and the rechargeable battery. It not only has the characteristics of rapid charging and discharging of the capacitor, but also has the energy storage characteristics of the battery. Farad capacitor is a new type of device that stores energy through the interface layer formed between electrode and electrolyte. When the electrode is in contact with the electrolyte, due to the effect 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. 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 on 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. Electric double-layer capacitors can be divided into carbon electrode double-layer supercapacitors, metal oxide electrode supercapacitors and organic polymer electrode supercapacitors according to different electrode materials. Compared with battery and traditional physical capacitor.

Application field:

Super capacitors are widely used in automobile motor starting, solar energy, solar energy storage, cordless phones, mobile phones, digital cameras, smart appliances, electronic toys, smart door locks, smart meters, MP3, PDA, DVD, VTR, GPS, PLC, fax machines, audio equipment, rice cookers, electric water heaters, self powered super flashlights, printers, tail lights, electronic

The double-layer supercapacitor module has the following advantages:

1. Green energy (activated carbon) does not pollute the environment.

2. Long service life (100000 times of charging); The lead-acid battery has a short life (500 times of charging), is easy to be damaged and difficult to manage. It is 20-200 times as long as the lead-acid battery and can share the same fate with the equipment.

3. Fast charging speed (0.3 seconds - 15 minutes); Lead-acid batteries have a long charging time (5-8 hours). Many batteries have a long charging time and a short driving range.

4. High charge-discharge efficiency (98%); The charge and discharge efficiency of lead-acid battery is low (70%);

5. High power density (10.000W/kg); The power density of lead-acid battery is low (300W/kg), more than 30 times worse.

6. Completely maintenance-free, operating temperature range (- 40~50); The driving range of lead-acid battery electric vehicles at - 40 ℃ is reduced by 90%, and the supercapacitor is only reduced by 10%.

7. In the electric bus, the energy recovery is strong, and the emergency braking energy recovery is up to 75%; The energy recovery of lead-acid batteries is only 5%, which is too important for public buses and can save a lot of fuel.

8. The relative cost is low. The price of supercapacitors is twice as high as that of lead-acid batteries, and the price will drop after mass production; However, the service life of supercapacitors is 10 times longer than that of lead-acid batteries, which is very important for the industrialization of public buses.

9. It has the function of over-temperature and over-pressure automatic alarm, which can better protect other equipment and ensure the normal operation of the equipment;
