Can Supercapacitors Surpass Batteries for Energy Storage? (.PDF Download)

A supercapacitor is a double-layer capacitor that has very high capacitance but low voltage limits. Supercapacitors store more electrical energy, rated in farads (F), at an electrode-electrolyte interface than electrolytic capacitors. They consist of two metal plates that are coated only with a porous material known as activated carbon. As a result, they have a bigger area for storing much more charge...
