25F 2.7 Volt 500f Capacitor Long Cycle Life For Switching / Power Supply

25F 2.7V Super Capacitor Cycle Life Is Long Good Ultra-Low Temperature Characteristics

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.

Application Scenarios of Supercapacitors

If you need a device with high power characteristics, a certain amount of energy to drive electrical appliances, long-term maintenance-free, and use in a wide temperature range, especially in places with strict safety requirements at minus 30 to 40 degrees, it is time to choose A suitable supercapacitor. The application scenarios of supercapacitors are very extensive. Let us list some common ones:
Smart three meters water, electricity, gas
Instantaneous high power, such as UAV ejection device;
Short-term current supply, such as police flashlights;
Frequent acceleration (downward) and deceleration (upward) working conditions, such as braking energy recovery device;
Diesel vehicle starting in extreme cold weather or battery failure;
Backup power supply for wind power generation, solar thermal power generation, nuclear power and other power generation terminals;
All kinds of long-life, high reliability, maintenance-free, high power density backup power supply;

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;
(9) The capacity range is usually 0.01F--1000F, and the withstand voltage is often low (a few volts to more than ten volts, and the newly developed one is only more than twenty volts).
Supercapacitors can be made into super capacitor modules for high capacity requirements.

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.
