High Temperature Ultracapacitor Super Capacitor Cylindrical 1F~400F
2.7V
A supercapacitor is first of all a capacitor, the word "super",
that is, compared with ordinary capacitors, it has a large electric
energy storage capacity, and at the same time it retains super
power characteristics. This opens up opportunities for certain
applications - fast charge and fast discharge, fast charge and slow
discharge (long discharge time), slow charge and fast discharge.
Fenghua supercapacitors have some other unique energy storage
advantages:
Fast charging: charging for 10 seconds to 10 minutes can reach more
than 90% of the capacity.
Working environment: The working temperature of the supercapacitor
is -40°C~70°C, which meets most environmental requirements;
Safety performance: acupuncture, extrusion, vibration, impact,
combustion, etc. will not explode;
Service life: It can be charged and discharged more than 1 million
times, which is longer than ordinary capacitors.
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;
(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.
