In addition to ultra-high power density (10 ~ 100 kW kg −1) compared to other energy conversion and storage devices, SCs have merits including operation over a wide range of temperatures (−40 ~ 80 C), high efficiency, and fast charge/discharge rates (in seconds) [3, 4, 34].].
What is a supercapacitor and how does it work? A supercapacitor (also called an ultracapacitor or electrochemical capacitor) is a type of electrochemical energy storage device. It is superficially similar to a conventional capacitor in that it consists of a pair of parallel-plate electrodes, but...
The key feature of supercapacitors, for example with respect to batteries, is their very high power density: they are able to charge or discharge within a few seconds.
Supercapacitor discharge time varies with capacitance and discharge current. For example, a 1F supercapacitor discharges in about 10 seconds with a 0.1A current, while a 100F supercapacitor takes around 1000 seconds. Discharge times decrease as capacitance or discharge current increases, illustrating the rapid energy …
