Graphene application developments though have lead to new possibilities for energy storage, with high charge and discharge rates, which can be made very cheaply. But before we go into specific details, it would be sensible to first outline the basics of energy storage and the potential goals of developing graphene as a supercapacitor.
The maximum capacitance of a graphene supercapacitor is about 12 kilofarad as of 2013. A supercapacitor whose positive electrode is made of nickel-hydroxide-graphene composite and negative electrode from porous graphene has a specific capacitance of approximately 220 F/g.
Since Stoller described the first graphene supercapacitor in 2008, significant developments have been made during this last decade in the development of new graphene-based electrodes.
