Definitions

  • This invention deals with graphene platelet nano composites with metal or metal oxide, and graphene platelet nano coated with metal or metal oxide.
  • the coated and composited particles are useful as electrodes and for electrical applications.
  • Graphite is formed by many layers of carbon in highly structured platelets. These platelets, when separated from the graphite superstructure, are collectively called graphene. Graphene has interesting chemical, physical, and electrical properties. These properties make graphene a highly valued product. The quality of the graphene, as defined by particle diameter, particle width, and surface area, determine its industrial utility. It is advantageous to coat or composite graphene with metal particles for electrical applications.
  • Graphene produced by media ball milling has very small particle size with a relatively high surface area. It is uniquely suited to make nano-composites or coatings by coating or admixing other particles. Metals or metal oxides can be coated or formed into composites with the high surface area, relatively low aspect ratio graphene. It is believed by the inventors herein that the materials of this invention have unique aspect ratios. Ground graphite admixed with silicon has an aspect ratio fairly close to 1, graphene from a GO process, epitaxially grown graphene, or graphene from an intercalated—heating process has a very high aspect ratio. The moderate aspect ratio graphene of this invention better coats 1 to 4 micron particles and better mixes with even small nano-particles.
  • Native graphite has a very high G/D ratio.
  • Graphite ground to amorphous powder has the G/D ratio.
  • the material of the instant invention starts high and tends toward 2 the more the material is processed.
  • Amorphous graphite also has a G peak red shift to 2000 cm ⁇ 1 .
  • the material of the instant invention may have a small red shift, but from the quality of the data it is hard to determine.
  • the very high surface area and aspect ratio confirms it is largely graphene nano-platelets.
  • Mechanically exfoliated graphene is distinct from ground graphite, in that, it maintains the strong crystalline sp2 structure. As graphite is ground to amorphous, the ratio of G to D Raman lines tends to 2 and the G line red shifts from 1560 cm ⁇ 1 to 2000 cm ⁇ 1 .
  • the G peak is referred to as the graphene peak.
  • the D peak referred to as the Disorder peak. The more graphite is ground, the more the G peak is reduced and the D peak is increased.
  • the added particles are larger than the graphene, they are coated with graphene, and if they are about the same approximate size, a nano-composite forms.
  • the nanocomposites are useful for producing electrodes, especially for battery and capacitor applications.
  • FIG. 1 is a graph of battery performance of a Si/graphene (200-250 m 2 /g, 100 minutes processing time).
  • the exfoliated material has a particle size of 10 microns by 5 nm thick, or less.
  • the dry milling is controlled by controlling the surface energy of the milling media in addition to controlling the hardness of the milling media.
  • a second embodiment that is a process of dry milling particulate materials, wherein at least one of the particulate materials is a layered material, in the presence of a particulate material selected from the group consisting of i. ceramic, ii. glass, and iii. quartz, to obtain a composition wherein the layered material is exfoliated and wherein the particulate material is coated with the exfoliated material.
  • the exfoliated material has a particle size of 500 nanometers or less.
  • the dry milling is controlled by controlling the surface energy of the milling media in addition to controlling the hardness of the milling media.
  • a fourth embodiment there is a composited product obtained by the first embodiment and a coated product obtained by the second embodiment.
  • the graphene produced by the methods of this invention has a relatively narrow aspect ratio, greater than graphite.
  • aspect ratios above 5 and below 200 are preferred and more preferred are aspect ratios above 10 and below 25.
  • the small that is, 1 to 5 nanometers thick, and 50 to 100 nanometers diameter, high surface area (above 500 BET), medium aspect ratio graphene, is a unique size for coating with small metal or metal oxide particles.
  • the metals useful in this invention are the metalloid silicon, and the metals tin, iron, magnesium, manganese, aluminum, lead, gold, silver, titanium, platinum, palladium, ruthenium, copper, nickel, rhodium, and alloys of any of the above.
  • the plastic milling media useful in this invention has a hardness on the Brinell Scale in the range of 3 to 100.
  • the plastic milling media is selected from the group consisting essentially of polyacetals, polyacrylates, such as, for example, methylmethacrylate, polycarbonate, polystyrene, poly-propylene, polyethylene, polytetrafluoroethylene, polyethylene-imide, polyvinylchloride, polyamine-imide, phenolics and formaldehyde-based thermosetting resins, and alloys of any of the plastics named.
  • the particulate metal oxides useful in this invention are metal oxides selected from silicon, tin, iron, magnesium, manganese, aluminum, lead, gold, silver, titanium, platinum, palladium, ruthenium, copper, nickel, rhodium, tungsten, cobalt, molybdenum, and alloys of any the above named metal oxides, wherein the metal and metal oxide particles have a size of 100 microns or less. Preferred are particle sizes of 10 microns or less, and most preferred are particle sizes of 5 microns or less.
  • Metal carbides, metal nitrides are useful in this invention, as well as non-layered materials.
  • Graphene useful in this invention is preferred to have a thickness of 5 nm or less.
  • the polymethylmeth-acrylate balls can be replaced with polycarbonate, polystyrene, polypropylene, polyethylene, polytetrafluoroethylene, polyethyleneimide, polyvinylchloride and polyamide-imide to control milling efficiency, graphene size, porosity distribution and surface area at a fixed milling time, contact quality between Si and graphene surface.
  • the surface area of the Si/graphene composite produced can be varied from 100 m 2 /g to 700 m 2 /g depending on milling time (60 to 500 min.) and Si/graphene composition and type of ball materials.
  • the result for the battery performance of a Si/graphene (200 to 250 m 2 /g, 100 min. processing) sample as an anode for a lithium ion battery is plotted infra.
  • the Si/graphene shows high capacity (>800 mAh/g, electrode loading) over 35 cycles at 100 mA/g, which supports the low cost, simple, time-saving, environmentally benign, flexible way to produce high performance graphene-based composite materials for energy applications. Some fluctuation of the capacity is due to the variation of temperature.
