    Abstract: Embodiments described herein relate to anode particles coated with lithium, and methods of producing the same. In some aspects, a method can include melting lithium and a first plurality of graphene flakes together to form a suspension, coating an anode particle with the suspension to form a lithiated particle, the anode particle coated with a second plurality of graphene flakes, and applying a pressure to the lithiated particle. In some embodiments, the method can include heating the lithiated particle. Heating and application of pressure can facilitate diffusion of lithium toward a center region of the lithiated particle. In some embodiments, the method can further include coating the anode particle with the second plurality of graphene flakes. In some embodiments, the anode particle can include silicon, a silicon alloy, silicon oxide, and/or silicon dioxide.

    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 to non-oxidized graphene-based anti-viral surfaces, and methods of producing the same. In some embodiments, a method of forming an anti-viral surface can include mixing a non-oxidized edge-functionalized graphene with a catalyst and a thermoset material to form a mixture, applying a high-shear mixing process to the mixture to form a mixed liquid, and coating the mixed liquid onto a base surface to form the anti-viral surface. In some embodiments, the method can further include chemically treating the graphene to produce the non-oxidized edge-functionalized graphene. In some embodiments, the thermoset material can include a thermoset matrix. In some embodiments, the method can include dispersing the non-oxidized edge-functionalized graphene into the thermoset matrix via the high-shear mixing. In some embodiments, dispersing the non-oxidized edge-functionalized graphene into the thermoset matrix can be via a ball mill, a high-shear mixer, and/or a homogenizer.

    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.
