Abstract
A method for fabricating a composite material includes forming an emulsion mixture of active material particles and graphene emulsion droplets containing immiscible first and second solvents and a solid-state emulsifier of graphene, wherein the first and second solvents are adapted such that the second solvent resides in an interior of the graphene emulsion droplets with the first solvent as an exterior solvent, and the active material particles reside in the interior of the emulsion droplets; wherein a boiling point of the second solvent is lower than that of the first solvent; and drying the emulsion mixture with subsequent evaporation of the second solvent and the first solvent through fractional distillation to form the composite material having each surface of the active material particles conformally coated with said graphene.
