3.0v 3000f Super Capacitor Good Reversibility And Long Service Life
Guide pin 2.7 ~ 3.2V series lead-in lithium-ion capacitor. This series of products is a new energy storage device integrating
super capacitor and lithium-ion battery technology. The two poles are separated by a diaphragm, the electrolyte is filled in the
internal space of the unit, the aluminum shell is sealed with a rubber plug, and the wire terminals at the two poles are located
at the top of the product. Lithium ion capacitors have the intermediate characteristics of supercapacitors and lithium-ion
batteries. They have the advantages of small volume, large capacity, fast charging, high energy density and power density. The
products are mainly used in the fields of intelligent three meters, intelligent toilets, intelligent locks, security monitoring,
etc sensors, GPRS positioning, electric tools, electronic cigarettes, etc.
The process flow of the supercapacitor is: batching→mixing→electrode making→cutting→assembling→liquid injection→activation→testing→packaging.
Supercapacitors are structurally very similar to electrolytic capacitors, their main difference being the electrode materials. The electrodes of early supercapacitors use carbon. The carbon electrode material has a large surface area, and the capacitance depends on the surface area and the distance between the electrodes. The large surface area of this carbon electrode plus the small electrode distance make the capacitance of the supercapacitor It can be very large, and most supercapacitors can achieve Farad level, and the capacitance range can reach 1-5000F under normal circumstances.
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;
