NOVELTY - A graphene-embraced anode particulate comprises core comprising carbon or graphite particles decorated with anode active material, where carbon or graphite particles have a diameter or thickness of 500 nm to 50 mu m, and anode active material, in a form of particles or coating, having a diameter or thickness of 0.5 nm to 2 mu m, is bonded to or embedded into surfaces of carbon or graphite particles; and embracing shell embracing or encapsulating the core and comprising multiple graphene sheets and having a thickness of 0.34 nm to 5 mu m. USE - A graphene-embraced anode particulate for powder mass for use as anode material of an anode electrode of a lithium battery (all claimed). ADVANTAGE - Graphene-embraced graphite-supported anode active material particles or coating can be produced in a simple, fast, scalable, environmentally benign and cost-effective manner. Unlike the chemical intercalation and oxidation (which requires expansion of inter-graphene spaces, further expansion or exfoliation of graphene planes, and full separation of exfoliated graphene sheets), the method directly removes graphene sheets from a source graphitic material and transfers these graphene sheets to surfaces of anode active material-decorated carbon or graphite particles. No undesirable chemicals (e.g. sulfuric acid and nitric acid) are used. Unlike oxidation and intercalation, pristine graphene sheets can be transferred onto the composite particle surfaces. The sheets being free of oxidation damage allow the creation of graphene-encapsulated particle products with higher electrical and thermal conductivity. Contrary to common production methods, a washing process requiring substantial amounts of water or solvent is not needed with the instant method. Unlike bottom up production methods capable of producing small graphene sheets, large graphene sheets can be produced with the instant method. Unlike chemical vapor deposition (CVD) and solution-based metalorganic production methods, elevated temperatures are not required to reduce graphene oxide to graphene and to convert metalorganic compounds to pure metal. This greatly reduces the opportunity for undesirable diffusion of carbon into the electrode active material. Unlike CVD and solution-based metalorganic production methods, this process is amenable to almost any electrode active material. The electrode active material does not need to be a compatible template or catalyst, as is required for the CVD process. The method is amenable to industrial scale production in a continuous energy impact device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lithium-ion battery comprising the anode comprising multiple anode particulates as an anode material, a cathode, and an electrolyte.
