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;
