Hybrid farad capacitor

Product introduction:

     Pseudo-capacitor (Pseudo-capacitor) is a highly reversible chemical adsorption/desorption or oxidation/reduction reaction formed by the underpotential deposition of living materials on the surface of the electrode or in the two-dimensional or quasitwo-dimensional space of the bulk phase, resulting in capacitance related to the electrode charging potential, also known as Faraday quasi-capacitor; A typical pseudo-capacitor is composed of metal oxides, such as ruthenium oxide, and its specific capacitance is up to 760F/g. However, because ruthenium oxide is too expensive, cobalt oxide, nickel oxide and manganese dioxide have been used to replace it; Hybrid capacitor is composed of a half carbon electrode forming a double-layer capacitor and a half surface reaction of conductive polymer or other inorganic compound or electrode embedding reaction electrode. At present, there are carbon/nickel oxide hybrid capacitor products in the aqueous electrolyte system, and carbon/carbon (lithium ion embedded reactive carbon material), carbon/manganese dioxide and other hybrid capacitors in the organic electrolyte system are being developed.

Advantages of double-layer super Faraday capacitor：

High reliability, cycle life: > 500000 times Good frequency characteristics, high temperature resistance, low temperature rise, adhesion High energy conversion efficiency Low use loss Green power supply The charging circuit is simple, and there is no need to charge the battery and other charging circuits, and there is no need to maintain it for free long-term use

Dimensions (unit: mm)

Application field:

1) Portable equipment: notebook computer, video camera, PDA, digital camera, portable DVD, etc 2) Household appliances: two-way radios, walkie talkies, electric toys, electric bicycles, emergency lighting 3) Military equipment 4) Medical treatment 5) Electric tools

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;
