Difference between Capacitor and Supercapacitor



Difference between Capacitor and Supercapacitor



Supercapacitor, also known as Electrical Doule-Layer Capacitor (EDLC), Gold Capacitor, Farad capacitor. The biggest difference between supercapacitor and capacitor is that supercapacitor is an electrochemical physical component, but does not react chemically itself, the biggest supercapacitor has a particularly large storage capacity, reaching farad-level capacity. How do you increase the area of the two poles? Supercapacitors store energy by injecting electrolytes. Under the action of the electrode, the charge on the electrode surface will attract the heterogeneous ions in the surrounding electrolyte solution, causing these ions to attach to the electrode surface to form a double charge layer, constituting a double layer capacitance.



Because the distance between the two charge layers is very small (generally less than 0.5mm), and use of special electrode structure is adopted, the surface area of the electrodes is increased by ten thousandfold, resulting in a tremendous amount of electrical capacity.



Capacitor supercapacitors combine the physical characteristics of ordinary capacitors with many advantages that conventional capacitors and batteries cannot match:



1. Supercapacitors have a large Faraday-level electrical capacity, which is much larger than ordinary capacitors.



2. Supercapacitors can instantly release power nearly ten times higher than ordinary batteries, and will not be damaged.



3. The cycle life of charge and discharge is more than 100,000 times, which is one of the biggest advantages. Conventional batteries can only be recharged a few hundred times.



4. Supercapacitors can be used normally in an ambient temperature of 40 degrees to 60 degrees, the performance of traditional batteries will be greatly reduced in low temperature.



5. Super charge holding supercapacitor capacity, leakage is very small, traditional batteries need to be charged frequently to maintain the state.



6. Supercapacitors can charge rapidly, its speed is dozens of times faster than ordinary batteries, a few minutes can be full of electricity required for a car.



7. Largest supercapacitors will not inherently pollute the environment, truly maintenance-free, while traditional batteries are still polluting.



In some fields, supercapacitors already have a promising future, for example, mobile phone batteries made of supercapacitors can be fully charged in just one minute, and are not afraid of subzero temperatures. There are different types of supercapacitor.



They are used in high power starting motors, such as those for large diesel engines or gas turbines, which require large transient currents. With conventional batteries, the life expectancy will be very short, but supercapacitors are perfectly suited to the task.

Supercapacitors for UPS

Image
The function of the super capacitor ups is often determined in the first few seconds to a few minutes after the power failure or the instantaneous collapse of the grid voltage. The battery needs to provide power during this period. The shortcomings of the battery itself need regular maintenance and short life, so that the UPS is running. It is necessary to always check the state of the battery. In a data protection backup system, the time required by the UPS is relatively short. The advantages of ultracapacitor ups are particularly pronounced, with output currents rising to hundreds of amps or even thousands of amps with almost no delay, and fast charging, energy storage in a short period of time, and 50,000 cycle life Do not need care for ten years, so that ups supercapacitor is truly maintenance-free. As one of supercapacitor manufacturers , we can offer kinds of super capacitor for sale, if you have needs, please contact us.
