Super Capacitor 2.8V 3000F Long Life Fast Charge And High Efficiency​

Super capacitor is a brand-new capacitor based on the interface electric double layer theory proposed by German physicist Helmholtz. As we all know, the surface of the metal electrode inserted into the electrolyte solution and the liquid surface will have excess charges of opposite signs, which will cause a potential difference between the phases. Then, if two electrodes are inserted into the electrolyte at the same time, and a voltage lower than the decomposition voltage of the electrolyte solution is applied between them, the positive and negative ions in the electrolyte will move rapidly to the two poles under the action of the electric field, and will be separated at the two poles. The surface of each electrode forms a tight charge layer, that is, an electric double layer. The electric double layer formed by it is similar to the polarization charge generated by the dielectric in a traditional capacitor under the action of an electric field, thereby producing a capacitive effect. The close electric double layer approximates Compared with flat plate capacitors, however, because the distance between the charge layers is much smaller than that of ordinary capacitors, it has a larger capacity than ordinary capacitors.

The process flow of the supercapacitor is: batching→mixing→electrode making→cutting→assembling→liquid injection→activation→testing→packaging.

The exact details of supercapacitor construction depend on the application and use of the supercapacitor. These materials may vary slightly due to manufacturer or specific application needs. The commonality of all supercapacitors is that they all contain a positive electrode, a negative electrode, and a diaphragm between the two electrodes. The electrolyte fills the two pores separated by the two electrodes and the diaphragm.

The structure of the supercapacitor. It 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 separator should meet the conditions of having the highest possible ionic conductivity and the lowest possible electronic conductivity, generally an electronic insulating material with a fiber structure, such as polypropylene film . The type of electrolyte is selected according to the nature of the electrode material.

Features of super capacitors:

(1) The charging speed is fast, and it can reach more than 95% of its rated capacity by charging for 10 seconds to 10 minutes;
(2) The cycle life is long, the frequency of deep charge and discharge cycles can reach 10,000 to 500,000 times, there is no "memory effect", and there is no problem of over-discharge;
(3) The high current discharge capacity is super strong, the energy conversion efficiency is high, the process loss is small, and the high current energy cycle efficiency is ≥90%;
(4) High power density, up to 300W/KG~5000W/KG, equivalent to 5~10 times of battery;
(5) The raw material composition, production, use, storage and dismantling process of the product are not polluted, and it is an ideal green power source;
(6) The charging circuit is simple, no charging circuit like rechargeable battery is needed, and long-term use is maintenance-free;
(7) Good ultra-low temperature characteristics, temperature range -40 ° C ~ +70 ° C;
(8) Easy to detect, the remaining power can be read directly;

Supercapacitor should be a general term for capacitors with extremely high energy storage density and fast discharge performance. The supercapacitors produced by our factory have super power, super high current, super wide working range, super high safety, super long life, etc. The characteristics of energy storage and the combined use with other energy storage products have become mainstream.
