Properties and Applications of Graphene and Graphene Oxide Derivatives
Department of Physics
Central Michigan University
When the dimensionality of graphene is reduced to a quasi-one-dimension, armchair and zigzag edges appear. The presence of these edges produces a variety of electronic behaviors and affects not only the reactivity of the carbon material toward the adsorption of adatoms, such as Li, but also their diffusion characteristics. Furthermore, upon oxidation and reduction some of these properties are altered and can be optimized for particular applications. However, the question remains on whether these properties can be successfully controlled for the targeted applications. I will present our computational work on Li adsorption in these systems combined with our experimental results on graphene oxide derivatives and discuss the current challenges facing the applications of these materials in battery technologies.
