However, graphene, which stores charges only on the surface of the electrode, exhibits relatively low specific capacitance when utilized in supercapacitor applications. Studies have indicated that a single electrode material cannot match the high energy and power density requirements for supercapacitors.
The high specific capacitance of supercapacitors is a crucial factor for their industrial application. However, various methods using graphene composite materials as active electrode materials have been employed to enhance the specific capacitance of supercapacitors.
A similar but more limited study in 2020 compared graphene and activated carbon to show that the specific capacitance of graphene-based supercapacitors was markedly lower than that of activated carbon, likely due to the presence of graphene oxide.
Graphene-based supercapacitors are more expensive. Because graphene-based supercapacitors are a newer technology, their production has not yet reached economies of scale. Furthermore, due to more stringent quality requirements, graphene continues to be more expensive to produce than activated carbon.
Graphene supercapacitors are already on the market, and several companies, including Skeleton Technology, the CRRC, ZapGoCharger, and Angstron Materials are developing such solutions. Read our Graphene Supercapacitors market report to learn more about this exciting market and how graphene will effect it.
Several materials exist that are researched and suggested to augment supercapacitors as much (or even more than) graphene.
