摘要： A 2D material such as graphene is produced on a forming sheet disposed on a carrier and exposed to a donor gas within a furnace. A first furnace surface is disposed immediately adjacent to and spaced apart from the forming sheet to define a volume. A purge gas is used to purge the volume of undesirable molecules, such as oxygen, and then a donor gas is introduced into the volume to supply an element or molecule necessary for the formation of a 2D material. Multiple carriers and forming sheets are moved in a train into the furnace during the presence of the donor gas, and each forming sheet is heated to a temperature sufficient to form 2D material on the sheet. The furnace is constructed of a nonreactive material, such as quartz, and the first furnace surface is provided by a quartz plate. Gas passageways and gas ports are formed in the quartz plate with the ports extending through the first furnace surface. The ports are disposed in patterns that facilitate the production of a smooth nonturbulent laminar flow of gas within the volume. As gases are introduced into the furnace, the gases are constrained but they escape and are collected by a surrounding gas chamber. Undesirable gases are purged and desirable gases are maintained in both the furnace and the gas chamber.

摘要： 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.

摘要： A method for easily producing a graphite powder for use as a lithium secondary battery negative electrode material with small specific surface area while reducing energy consumption, and achieving high graphitization efficiency, includes melt-mixing a coke powder and a carbon precursor binder so that an amount of fixed carbon included in the carbon precursor binder is 5 to 15 parts by mass based on 100 parts by mass of the coke powder, to prepare a mixture, and pressing the mixture to prepare a compact, the coke powder being obtained by heating a green coke powder at 600 to 1450° C. in a non-oxidizing atmosphere, the green coke powder having a cumulative particle size at 50% in a volumetric cumulative particle size distribution of 5 to 50 μm; heating the compact in a non-oxidizing atmosphere to effect carbonization and graphitization to obtain a graphitized compact; and grinding the graphitized compact.

摘要： A method of manufacturing a graphene composite including an ultrasonic-wave pulverization post-treatment process. The method includes radiating a microwave on a mixture of graphite oxide and a conducting agent, dispersing a resultant material, obtained during the radiating the microwave, in a liquid and performing ultrasonic-wave pulverization, and freeze-drying particles subjected to the ultrasonic-wave pulverization. The post-treatment process is added to the method of manufacturing the graphene composite including the reduced graphene oxide using the graphite oxide, thereby manufacturing a graphene composite having improved bindability with spherical activated carbon used to manufacture an active material. Further, the post-treated graphene composite is used to manufacture the active material and the supercapacitor, and accordingly, the active material can be thinly and densely applied to provide a supercapacitor having improved performance.

摘要： A process for derivatization of an elemental carbon surface comprising exposing the carbon surface to a reaction mixture containing a thiol and a free radical initiator, and inducing decomposition of the initiator to free radicals so that moieties from the thiol become covalently attached to the carbon surface. The process can derivatize carbon with a redox active compound having a functional group which can be converted electrochemically between reduced and oxidized forms. Such derivatized carbon may be used in an electrode of an electrochemical sensor.
