Future Prospects and Challenges of Graphene-Based Supercapacitor

Paul Thomas, Nelson Pynadathu Rumjit, Chin Wei Lai, Mohd Rafie Bin Johan

According to the statement made by IUPAC (International Union of Pure and Applied Chemistry), graphene is distinguished as a carbon monolayer of the graphite structure. It can be described by analogy to a polycyclic aromatic hydrocarbon of quasi-infinite size. Over the past few years, graphene-based materials have gained immense attraction as next-generation material inherited with its better mechanical characteristics, excellent electrical conductivity and better thermal conductivity as contrasted with other similar materials. In the subsequent section, the new aspects of next-generation of supercapacitors with modified graphene materials including metal oxide/graphene composites, activated graphene, reduced graphene, doped graphene, and polymer/graphene composites will be reviewed and discussed. Moreover, advantages and drawbacks of these resultant composite materials applied in supercapacitor application are summarized in this chapter.
