- Abstract: In this work, we innovated traditional electrochemical exfoliation methods to produce high-quality graphene. By modifying an electrolytic cell with graphite sheets and employing an electric field, we achieved better ion intercalation. Our physical modeling and Raman spectroscopy confirmed less defective graphene compared to conventional methods. A subsequent design using an organic-aqueous parallel exfoliation method yielded thinner graphene layers, which is supported by SEM characterization, further enhancing the quality of the produced graphene.
