Abstract: Embodiments described herein relate generally to systems and methods for manufacturing a master batch with a graphitic material dispersed in a polymer matrix. In some embodiments, a method for manufacturing the master batch can include combining the graphitic material with a polymer, adding a supercritical fluid to the mixture, and depressurizing the supercritical fluid to remove the supercritical fluid. In some embodiments, the method includes mixing the graphitic material and the polymer for a first time period to form a first mixture and transferring the supercritical fluid to the first mixture to form a second mixture. In some embodiments, the method includes mixing the second mixture for a second time period and depressurizing the second mixture to allow the supercritical fluid to transition to a gas phase.

Abstract: Embodiments described herein relate generally to the large scale production of functionalized graphene. In some embodiments, a method for producing functionalized graphene includes combining a crystalline graphite with a first electrolyte solution that includes at least one of a metal hydroxide salt, an oxidizer, and a surfactant. The crystalline graphite is then milled in the presence of the first electrolyte solution for a first time period to produce a thinned intermediate material. The thinned intermediate material is combined with a second electrolyte solution that includes a strong oxidizer and at least one of a metal hydroxide salt, a weak oxidizer, and a surfactant. The thinned intermediate material is then milled in the presence of the second electrolyte solution for a second time period to produce functionalized graphene.

Abstract: Embodiments described herein relate generally to large scale synthesis of thinned graphite and in particular, few layers of graphene sheets and graphene-graphite composites. In some embodiments, a method for producing thinned crystalline graphite from precursor crystalline graphite using wet ball milling processes is a disclosed herein. The method includes transferring crystalline graphite into a ball milling vessel that includes a grinding media. A first and a second solvent are transferred into the ball milling vessel and the ball milling vessel is rotated to cause the shearing of layers of the crystalline graphite to produce thinned crystalline graphite.

Abstract: Embodiments described herein relate to anode particles produced in part from discarded graphite particles, and methods of producing the same. In some aspects, a method of forming carbon-coated anode particles can include mixing a first plurality of particles, a second plurality of particles, and a plurality of graphene particles to form a dry powder, the first plurality of graphite particles including particles rejected from a graphite spheronization process, the second plurality of graphite particles including particles rejected from a graphite micronization process, mixing the dry powder with water and a carbon-containing liquid to form a slurry, spray-drying the slurry to form an agglomerated mix, and heating the agglomerated mix to form carbon-coated anode particles. In some embodiments, the spray-drying includes atomizing the slurry to form droplets. In some embodiments, the spray-drying can include heating the droplets in a heated chamber to form dried particles.
