Supercapacitor is Capacitor 1. platent ffectively have a much bigger area af the distance between them is nilich smaller, because the seperator between them works in a different way to a conventional dielectric. Although ultra apsuper used interchangeably, youally built from different materials 4 structured in slightly different ways, So they stove defferent aniruch of energy. Like capacitor, super has two plates that ane seperated Plates are made from metal coated with a porous substance such as powdery, activated Charcoal, which effectively gives them biger area for stiring asargymuch more chang. Unlike capacilor, in a super capacitor, there is no dielectric as such. Instead both plates are soaked in an electrolyte, and seperated by a. very thin insulator (which might be made of Carbin ipaper or plastic). electrode material Working • when plates are charged up, an opposite charge forms on either side of the Seperator, crealing what is called an electric double layer. Thats why super reffered to as double layer capacities, electne dl C. (GALC). Capacitance of a capacitor increases as the area of the plates increases and as the distances between the plates decreases. Application Electrical eg of flywheels in machines -"energy reservoirs" tha smooth out power supplies to electrical af electronic equipment. • Connected to batteries to regulate thepower they supply. In wind turbines, where very large supercapacitors help to smooth out the inlemittent power supplied by the rund. In electric af hybrid vehicles, Supercapacitors are increasingly being used as lemperory energy stores for Regenerative braking
