Advantages and disadvantages of using supercapacitors

Supercapacitors are not always superior in every aspect of application, which requires proficiency in mastering the advantages and disadvantages of the equipment when using supercapacitors. Due to limitations in production skills, there is still a lack of equipment and debugging when using supercapacitors in China. Many devices experience circuit failures due to the blind use of supercapacitors, which affects the overall functionality of the equipment. As a new product of capacitors, the advantages presented by supercapacitors outweigh the disadvantages.

Supercapacitor

(1) Advantages. Supercapacitors are upgrades to general capacitor equipment, which have implemented multiple improvements to the previous capacitors. The main advantages are:

① Capacitance. The conventional capacitors used in the early stage have a small storage capacity and can only meet the circuit requirements of small loads; The capacitance level of supercapacitors can reach Farad level, which can be suitable for more chaotic circuit operation needs.

② Circuit. Supercapacitors have lower requirements for circuit structure, do not require special charging circuits or controlled discharge circuits, and the operating time of capacitors will not be affected by overcharging or discharging.

③ Welding. Generally, capacitors cannot be soldered. When using supercapacitors in equipment, welding treatment can be carried out as needed to prevent poor battery contact and improve the functionality of capacitor components.

(2) Disadvantages. Through functional testing of supercapacitors, the editor found that this new type of capacitor also has drawbacks. For example: ① Leakage. The unreasonable position of supercapacitor equipment can easily cause electrolyte leakage and other problems, which damage the structural function of the capacitor Circuit. Supercapacitors are limited to the use of DC circuits because compared to aluminum electrolytic capacitors, supercapacitors have a larger internal resistance and are not suitable for the operation requirements of AC circuits Price. Because supercapacitors are a new generation of high-tech products, their prices were relatively high when they were first introduced to the market, which increased the cost investment of equipment operation.
