Graphene-Based Metal-Ion Batteries

Graphene, a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure, has inspired tremendous research interests in chemistry, physics, materials science, etc. Graphene can be synthesized by physical exfoliation and chemical methods. Graphene-based materials have shown great potential in metal-ion batteries due to their high carrier mobility, 2D structure, high surface area, and electrochemical stability. This chapter provides a comprehensive overview of graphene and its derivatives in the context of monovalent metal-ion batteries, specifically focusing on Li-ion and Na-ion batteries, as well as multivalent metal-ion batteries (Zn and Al ions). The working principles of graphene in its roles as electroactive materials, conductive additives, and protective coating for current collectors will be elucidated.
