6 Significant Properties Of Supercapacitors Helping Them Gain Fast Popularity
Unlike a cell, a capacitor stores energy by means of a static charge. There is no electro-chemical reaction. A supercapacitor is also known as an ultracapacitor. Some technocrats call it a double-layer capacitor. It is different from a normal capacitor by virtue of its capacity to exhibit very high level of capacitance.
Supercapacitors are finding increasing applications in various fields of engineering. A typical application for supercapacitors is found in UPS solutions, where they are used in conjunction with standby generators to maintain power while the generator starts.
Another example is for protection against short power interruptions resulting from the operation of upstream power distribution systems, such as auto transfers and auto reclose events. They are also invaluable for use as peak buffers in conjunction with any equipment that have short repetitive peak power requirements, such as MRI scanners.
Supercapacitors are gaining popularity owing to some excellent characteristics that they show. In this context following 6 properties are quite significant:
- Supercapacitors have theoretically unlimited cycle life
- Their low internal resistance allows flow of current at very high magnitude
- They get charged in seconds
- It’s not necessary to terminate charging, as they never get over-charged
- They get charged at low temperature
- They are very safe.
