Supercapacitor, also called electrochemical capacitor, electric double layer capacitor, gold capacitor and farad capacitor, is an electrochemical element developed in the 1970s and 1980s to store energy through polarized electrolyte.

Different from the traditional chemical power supply, it is a kind of power supply with special functions between the traditional capacitor and battery, mainly relying on double electric layers and redox pseudocapacitor charges to store electric energy. However, there is no chemical reaction in the process of energy storage. This energy storage process is reversible, which is precisely because this supercapacitor can be recharged and discharged hundreds of thousands of times.

The detailed structure of supercapacitor depends on the application of supercapacitor. These data may be slightly different due to the manufacturer or specific application needs. All Farad capacitor The commonness is that they all include a positive electrode, a negative electrode, and the gap between the two electrodes. The electrolyte fills the two pores separated by the two electrodes and the gap.

For circular or cylindrical packaged products, the electrode is cut into a reel method configuration. Solder the electrode foil to the terminal to expand the external capacitive current path.

Its basic principle is the same as that of other electric double layer capacitors, which use the double electric layer structure composed of activated carbon porous electrode and electrolyte to obtain super capacity.

Super capacitor manufacturer Its advantages are high power density, short charging and discharging time, long cycle life, and wide operating temperature scale. It is one of the largest electric double layer capacitors that have been put into mass production in the world.

Each part is: (1): polytetrafluoroethylene carrier; (2) : The active substance is pressed on the foam nickel collector; (3) : Polypropylene battery barrier.

Super capacitor module The components of can be different from product to product. This is determined by the geometry of the supercapacitor packaging. For the placement of prismatic or square packaging product parts, the internal structure is based on the setting of internal parts, that is, the internal collector is extruded from the stack of each electrode. These collector pads will be soldered to the terminals to extend the current path outside the capacitor.

The supercapacitor is composed of porous electrode materials with high specific surface area, collector fluid, porous battery barrier and electrolyte. The electrode data shall be closely connected with the collector to reduce the touch resistance; The barrier shall be satisfied with the condition of having the highest ionic conductivity and the lowest electronic conductivity as possible, which is generally the electronic insulation material of fiber structure, such as polypropylene film. The type of electrolyte is selected according to the nature of electrode data.
