Publication number: 20230062310Abstract: 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.Type: ApplicationFiled: July 5, 2022Publication date: March 2, 2023Applicant: NanoXplore Inc.Inventors: Marie BOZALINA, Philippe PERRET, Soroush NAZARPOUR

Publication number: 20230005638Abstract: 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 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.Type: ApplicationFiled: May 9, 2022Publication date: January 5, 2023Applicant: NanoXplore Inc.Inventors: Marie BOZALINA, Philippe PERRET, Soroush NAZARPOUR

Patent number: 11515519Abstract: A nanocomposite includes one or more graphene-based materials (GMs), a nitrogen-containing polymer (an N-polymer), and elemental sulfur (S). The nanocomposite is suitable for use as a stable, high capacity electrode for rechargeable batteries such as lithium-sulfur (Li—S) batteries. Example methods of fabricating a nanocomposite include the addition of an N-polymer to a dispersion (e.g., an aqueous dispersion) or slurry of GMs mixed with a sulfur sol. The N-polymer can interact strongly with the GMs to form a cross-linked network. In one embodiment, hydrothermal treatment of the aqueous dispersion or slurry is used to melt the sulfur such that it becomes distributed within the network formed by the GMs and the N-polymer. The resulting nanocomposite material can then be processed through the addition of one or more other binders and/or solvents, and formed into a final electrode.Type: GrantFiled: October 17, 2018Date of Patent: November 29, 2022Assignee: VoltaXplore IncInventors: Michael Pope, Debasis Ghosh, Yu Zhong, Soroush Nazarpour
