▎ 摘　　要

NOVELTY - Functionalized graphene is produced by combining crystalline graphite with 1st electrolyte solution which contains metal hydroxide salt, oxidizer, and/or surfactant; milling crystalline graphite in the presence of 1st electrolyte solution for 1st time period to produce thinned intermediate material; combining thinned intermediate material with 2nd electrolyte solution which contains strong oxidizer and metal hydroxide salt, weak oxidizer, and/or surfactant; and milling thinned intermediate material in the presence of 2nd electrolyte solution for 2nd time period. USE - Production of functionalized graphene for lithium-ion batteries. ADVANTAGE - Selective functionalization of graphene edges leads to preservation of desirable properties of graphene surfaces while using defected edges of graphene to enhance mixability and/or dispersibility of graphene in both polar and non-polar solvents. Functionalized graphene helps improve power density, energy density, and battery cycle life of a lithium-ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) production of functionalized graphene which involves transferring thinned graphite into a vessel, transferring metal hydroxide salt into the vessel in which metal hydroxide salt is formulated to release hydroxyl ion upon ionization by electrostatic charge, transferring solvent into the vessel in which solvent is formulated to facilitate diffusion of hydroxyl ion to allow bonding of 1st hydroxyl ion to edge of thinned crystalline graphite, transferring oxidizer into the vessel in which oxidizer is formulated to react with hydroxyl ion at the edge of thinned crystalline graphite to convert hydroxyl ion at the edge of thinned crystalline graphite into a carbonyl group, and rotating the vessel to generate the electrostatic charge; (2) production of functionalized graphene which involves transferring crystalline graphite into milling vessel which includes a media, transferring electrolyte solution into milling vessel, rotating milling vessel for 1st time period to cause shearing of layers of crystalline graphite to produce a thinned intermediate material, transferring strong oxidizer into milling vessel, and rotating milling vessel for 2nd time period to generate electrostatic charge; and (3) production of functionalized graphene which involves transferring crystalline graphite into 1st milling vessel which includes 1st media, transferring 1st electrolyte solution into 1st ball milling vessel, rotating 1st milling vessel to produce intermediate material, transferring intermediate material to 2nd milling vessel which includes 2nd media, transferring 2nd electrolyte solution into 2nd ball milling vessel, and rotating 2nd milling vessel to generate electrostatic charge. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the process of milling in a vessel containing graphite, grinding media, and electrolyte solution.
