Advantages and disadvantages of using supercapacitors

Supercapacitors are not superior in every aspect of the process, which requires the advantages and disadvantages of the device when using supercapacitors. Due to the limitations of manufacturing technology, there are still some shortcomings in installation and debugging when using supercapacitors in China. Many devices cause circuit failures due to blind use of supercapacitors, which affects the performance of the entire device. As a new product of capacitors, the advantages exhibited by supercapacitors are significantly greater than the disadvantages.


(1) Advantages. Supercapacitors are an upgrade of common capacitor devices, and many improvements have been made to early capacitors. The main advantages are: 1 capacity. Conventional capacitors used in the early days have a small amount of capacitance storage and can only meet the circuit requirements of small loads. The capacitance level of supercapacitors can reach the Farad level and can be adapted to more complex circuit operation needs. 2 circuits. Supercapacitors have lower requirements on the circuit structure, and do not need to be provided with special charging circuits and control discharge circuits, and the use time of the capacitors is not affected by overcharge and overdischarge. 3 welding. Ordinary capacitors cannot be soldered. When the supercapacitor is mounted, soldering can be performed as needed to prevent battery contact failure and other phenomena, and the performance of the capacitor component is improved.


(2) Disadvantages. Through the performance test of supercapacitors, I found that this new type of capacitor also has shortcomings. Such as: 1 leak. The installation position of the supercapacitor is unreasonable, which easily causes problems such as electrolyte leakage and damages the structural performance of the capacitor. 2 circuits. Supercapacitors are limited to the use of DC circuits. This is because the internal resistance of supercapacitors is larger than that of aluminum electrolytic capacitors, which is not suitable for the operation of AC circuits. 3 prices. Since supercapacitors are a new generation of high-tech products, they are relatively expensive when they are introduced to the market, increasing the cost of equipment operation.
