Screw Type Fast Charging Supercapacitor 2.7V 3000F For Automobile

Fast Charging 3.0v 3000f Super Capacitor Tages Of Small Volume Large Capacity​

Supercapacitors are used in a variety of applications. Used as a power balance power supply for lifting devices, it can provide super-large current power; used as a vehicle starting power supply, the starting efficiency and reliability are higher than traditional batteries, and can replace traditional batteries in whole or in part; used as traction energy for vehicles It can produce electric vehicles, replace traditional internal combustion engines, and transform existing trolleybuses; it can be used in the military to ensure the smooth start of tanks, armored vehicles and other combat vehicles (especially in cold winter), as a pulse energy source for laser weapons. In addition, it can also be used as energy storage energy for other electromechanical equipment.

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.

Outstanding features of supercapacitors

(1) The charging speed is fast, charging for 10 seconds to 10 minutes can reach more than 95% of its rated capacity;
(2) Long cycle life, the number of deep charge and discharge cycles can reach 1 to 500,000 times, and there is no "memory effect";
(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 the battery;
(5) There is no pollution in the composition of raw materials, production, use, storage and dismantling of the product, and it is an ideal green power source;
(6) The charging and discharging circuit is simple, no need for a charging circuit like a rechargeable battery, high safety factor, and maintenance-free for long-term use;
(7) Good ultra-low temperature characteristics, wide temperature range -40℃～+70℃;
(8) Easy detection, the remaining power can be read directly;
(9) The capacity range is usually 0.1F--1000F.

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.
