TRU Graphite-Graphene Consulting Team has a solid engineering, operations & business capability in graphite from ore resources, through to the manufacturing of upmarket value-added leading-edge graphite-graphene and synthetic graphite end-use products.

TRU Group Inc - expert at Clean Processing of Natural Graphite: The processing of graphite containing ore to achieve end-user specifications has environmental concerns. Historically lowest cost processing has been the priority but western processors face much stricter environmental restrictions than in China where most graphite originates. Availability of a high quality graphite ore that is amenable to advanced technology processing is one important factor in reducing environmental barriers. The processing to the high grades for li-ion batteries means thermal and/or chemical purification, micronizing, separation of fractions, spherizing and coating. Cost reduction is always a target and realized by process optimization as in other industries. Typically, thermal purification can be cheaper and cleaner but chemical methods of purification are enhanced by recycling and by-product processing. Western technology advances have gone a long way to meet environmental constraints. For example, high-tech spherizing and micronizing can determine the treatment type and level of purification.

TRU Graphite-Graphene Team is the most qualified and experienced available. It includes more than a dozen distinguished graphite-graphene experts who have each worked many years in executive management or as senior engineers / R&D scientists for high tech graphite companies: Graphit Kropfmühl AG Germany, GrafTech USA, Nacional de Grafite Brazil, POCO USA, Superior Graphite USA, TIMCAL, IMERYS GROUP and producers in China. Our team has hands-on experience in the design & engineering of graphite-graphene processes, plants and products - working extensively with many types of natural and synthetic graphite, natural flake graphite, vein, amorphous, ionic clays etc - with detailed knowledge of many different production methods. For example, our team has extensive knowledge of graphite anode & coating for lithium ion batteries. TRU approach is unique combining its high-tech north American-European graphite expertise with our graphite experts in Brazil & China to provide one of the strongest graphite teams available. We also have a access to a full (non-conventional) capability (in the USA & internationally) for graphite-graphene laboratory testing and piloting operations - from the routine to the most specialized globally. The TRU Graphite-Graphene Team has world-class capability for Feasibility Studies, Investor Due Diligence, Engineering & Technical Analysis in all aspects of graphite-graphene.

Matching graphite resource to high-tech niche applications has proved particularly important for the successful profitable graphite operations of today but the matching methods are technically complex - the downstream manufacturing (rather than the ore processing) being by far the major challenge. Indeed TRU in 2015 completed a conceptual feasibility study on what we discovered to be a previously unknown type of graphite: So different that we termed it “STAX Graphite” to highlight the ore’s unique natural Spheroidal, Thin, Aggregate and eXpanded morphology. TRU continues work on the assignment as of June 2016 with mineral processing testwork and product development experimentation in the United States. The earlier conceptual engineering of the integrated USA graphite facility included graphite production units for -

  • coated spherical graphite for rechargeable li-ion battery anodes
  • purified graphite >300 microns for graphite flexibles and converting
  • highest purified graphite powders <20 microns friction & specialty products.

Graphene, nanotubes, nanocarbon and fullerenes - TRU is capable in functionalized graphene, graphite oxide, intercalated graphites etc, and the upmarket value-added graphite base, intermediate or final products required of the modern graphite enterprise including -

• Graphite-metal composites • Exfoliated graphite/functionalized graphene • Intercalated graphite (ex. lithium-graphite) • Chemically-modified graphite (ex. graphite oxide) • Activated porous graphite • Graphite aerogel/aerosol

TRU Technical Assessment of Graphene Production and Product Development. Our definition of "Graphene" and its specification parameters for commercial graphene products : As of mid-2015 TRU was engaged in examining technical issues and advances in graphene production and the prospects for its commercialization of a major north american graphene-containing products developer. From a pure science view graphene is basically one single layer of sp2 bonded carbon atoms arranged in a honeycomb hexagonal lattice. The industry view today is controversial. TRU has developed a "grading protocol" for graphene founded on a TRU practical definition of graphene which includes up to ten layers because that is the point above which many unique properties of graphene are lost and they resemble those of graphite. The TRU definition then includes few layer graphene FLG and Multi-layer graphene MLG however excludes nanoplatelets GNP and ultrathin graphite UG and graphene-containing materials. The TRU developed Graphene Grading Protocol is based on four parameters: Number of Layers, Carbon Content, Impurity per Element, and Crystal Defects. In addition we have strong expertise in other specialty carbon technologies such as nanotubes, nanocarbon, and fullerenes. TRU has specialty expertise in carbon-carbon bonding, carbon-ceramic bonding and carbon-metal bonding. Also view -

Graphite containing carbon-carbon anode. TRU Group Inc was working in high-tech use of graphite in the early 2000's when it assisted a start-up to search for financing for a revolutionary lithium-ion battery with a graphite containing carbon-carbon anode. This carbon fiber anode material material consists of carbon reinforcement fibers and a carbon matrix. Generally, the carbon-composite fibres provide strength and electrical and thermal characteristics, and the matrix provides structural integrity and fills voids between fibres. The Li-Fiber cell cathode is Lithium Cobalt Oxide and electrolyte Lithium Hexafluorophosphate (LiPF6). Ninety per cent of the material cost for li-ion cells is associated with five cell components – overcharge / over-discharge protection circuit, cathode (LiCoO2 or LiNiCoO2) and anode (MCMB carbon) materials, electrolyte (LiPF6), and separator. The need for over-charge / over-discharge protection circuits or devices contributes significantly to the cost of lithium-ion batteries. The li-fiber battery would not overheat even in high energy capacity applications and requires no significant electronic protection circuit or heat management.

The main sponsor of that assignment are leading suppliers of aluminum graphite, nanotubes (allotropes of carbon with a cylindrical nanostructure), fullerenes (similar in structure to graphite) tru-group graphite market segments spinel and nanocarbons. In addition the firm is specialized in advanced graphite single or multilayer coatings. The carbon nonparasitic obtained from either arcing of graphite under water or thermal annealing of nanodiamonds are commonly called carbon nano onions (CNOs), or spherical graphite, as they are made of concentric fullerene cages. Carbon onion nanomaterials consist of spherical fullerene cores surrounded by onion-like nested spherical graphite layers.
