▎ 摘 要
NOVELTY - Microgranulation of aggregating precursor particles involves obtaining an amount of precursor particles having an average particle size of less than 1000 mu m, obtaining an amount of templating media having an average particle size of less than 500 mu m and a hardness which is greater than that of the precursor particles, preparing a mixture comprising the amounts of precursor particles and templating media, and subjecting the mixture to a high shear and high pressure application by aggregating the precursor particles into product particles. USE - Microgranulation of aggregating precursor particles used as graphite particulate e.g. aggregated graphite particulate such as lithium mixed metal oxide particulate and lithium transition metal oxide particulate for forming powder such as carbonaceous powders, mixed metal oxide powders and metal carbonate powders used in electrode for rechargeable battery, fertilizer, pharmaceutical, toner, pigment, filler and catalyst (all claimed). ADVANTAGE - The method enables improved microgranulation of aggregating precursor particles provides battery having excellent reversible capacity and reduced cell polarization. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a rechargeable battery, which comprises an anode electrode and a cathode electrode, in which at least one of the anode and cathode electrodes comprising product particles; (2) a graphite particulate, which comprises graphite particles are shaped as spheres or ovoid and comprising concentric nested spheres or ovoid of graphene layers, and graphene layers are randomly positioned on the surface of the concentric nested spheres or ovoid, excluding that the graphene layers are oriented such that their basal planes are tangential to the concentric nested spheres or ovoid, where the graphite particles have an average particle size of more than 2 mu m and an average spacing of less than 3.400 Angstrom ; (3) an aggregated graphite particulate, which comprises aggregates of graphite particles; (4) a lithium mixed metal oxide particulate, which comprises particles with a core of lithium nickel manganese cobalt oxide crystallites which are randomly oriented and have an average size of 1 mu m coated with smaller randomly oriented lithium nickel manganese cobalt oxide crystallites having an average size of 0.3 mu m; and (5) a lithium transition metal oxide particulate comprising particles of lithium transition metal oxide, which comprises particles comprising at least two transition metals containing magnesium, nickel and cobalt and having average particle size of 1-50 mu m and comprising crystallites vary randomly in shape and size throughout their interior. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a mechanofusion system.
