A review on synthesis of graphene-based materials for energy storage devices

The extraordinary properties of graphene have made application of this wonder material in multidisciplinary domains. Promising applications of graphene and its composites have been made a reality through enormous scientific efforts to date. In the present era, the attention has to focus on the right choice of methodology analogous to each application. The prospective product range of graphene is broad, and the attentiveness of each application would be deviated accordingly. We believe priority should be given to the most essential needs among the vast variety of opportunities. Here we focus on methods followed in the production of graphene and composites and their applications in energy storage devices including batteries, capacitors, and fuel cells. Physical, chemical, and biological methodologies followed in minute scale synthesis as well as mass level are discussed. The information would be supportive of the development of more effective energy storage devices based on graphene in soon.
