Graphene Synthesis Methods for Graphene Based Supercapacitors of the Solar Energy Systems

In the last decade, graphene as one of the novel engineering materials with unique properties has been strongly considered by researchers. Graphene based supercapacitors and transistors are one the most recent subjects in the case of solar energy systems modification fields. In this study, five main methods of producing graphene (micro-mechanical cleavage, Liquid-phase exfoliation, Graphene via graphite oxide, Graphene from mechanical milling of graphite, Electrochemical exfoliation of graphite) which are in the challenge of engineering and economics justifiable in using for supercapacitors, has been investigated. Subsequently, Liquid-phase exfoliation has been chosen as the best method of producing graphene for using in supercapacitors in the industry scale based on the investigations and comparison throughout advantages and limitations of the preceding methods.
