Supercapacitors are electrochemical energy storage devices that are capable of providing high power density and remarkable energy. These features make it an attractive device for different energy storage applications such as: electrical vehicles, back-up power systems, electronic components etc. They can complement or replace batteries in electrical energy storage and harvesting applications, when high power delivery or uptake is needed. Depending upon the charge storage mechanism as well as active material used, there exists different class of supercapacitors. First one is the...
