What are the advantages of Farad capacitors?

The service life of Farad capacitors is very long. Farad capacitors are different from ordinary batteries. They are a primitive electrochemical substance that does not undergo chemical reactions during storage. Farad capacitors can achieve Farad capacity in a small volume without the need for special charging and discharging. They are a green and environmentally friendly product. Farad containers can repeatedly transmit energy compared to batteries, unlike ordinary batteries, which reduces their service life. The service life of Farad capacitors is relatively long, with 500 times the number of charges and discharges compared to paved batteries, and a strong recycling rate. Farad capacitors are free of harmful chemicals, pollution-free, environmentally friendly, and suitable for use by export enterprises. The withstand voltage of supercapacitors is usually only 2.5V, and the allowable surge voltage is 2.7V. Therefore, for a single supercapacitor, the output voltage of the charger should not exceed 2.7V. As long as the working voltage of the supercapacitor is within the safe voltage range, the service life of the supercapacitor is long, and the number of cycles of charging and discharging can reach 100000 to 500000.

Due to the low working voltage of supercapacitors, it is often necessary to use multiple supercapacitors in series to increase the working voltage. Due to the imbalance of supercapacitors, it is necessary to ensure that the charging voltage of any supercapacitor does not exceed 2.5V. The solution is to use a battery balancer. 

Faraday capacitors have two main applications: the application of high-power pulses and the maintenance of instantaneous power. Advantages of high-power pulse applications: multiple power flows to the load in a short period of time; The advantages of instantaneous power maintenance applications: it requires continuous power increase like a load, and maintenance time generally exceeds ten seconds or a few minutes. A basic application of short-term power maintenance is the reset of the disk drive head in the event of a power outage. Different machines also have different requirements for the parameters of Farad capacitors. High power pulse applications utilize the small internal resistance of Faraday capacitors, while short-term power maintenance utilizes the large electrostatic capacity of supercapacitors.

The power density of supercapacitors is dozens of times higher than that of ordinary lithium batteries, and the requirements for charging circuits are not high, saving charging and discharging time. The number of charge and discharge cycles of supercapacitors exceeds 500000. If charged and discharged 20 times a day, it can be used continuously for 68 years. It greatly extends its service life. In addition, supercapacitors can be connected in series to form capacitor banks to increase larger storage capacity.
