  • Publication number: 20160197347
    Abstract: LMFP cathode materials are made in a mechanochemical/solid state process. The precursors are dried in a preliminary step to reduce the water content of the precursors of less than 1% by weight and preferably less than 0.25% by weight. The dried precursors are then dry milled and calcined to form particles of an olivine LMFP. The product has excellent specific capacity and capacity retention.

  • Patent number: 8481616
    Abstract: A two step method for preparing a filler composition, the filler composition useful to prepare a nanocomposite polymer and an epoxy nanocomposite coating. First, disperse a water dispersible filler material in a liquid comprising water, but without any added intercalation agent, to form a dispersion. Second, replace at least a portion of the water of the liquid with an organic solvent so that the water concentration of the liquid is less than six percent by weight to form the filler composition, the average size of at least one dimension of the filler material being less than two hundred nanometers upon examination by transmission electron microscopy of a representative freeze dried sample of the dispersion of the first step. A nanocomposite polymer can be prepared by mixing the filler composition with one or more polymer, polymer component, monomer or prepolymer to produce a polymer containing the filler composition.

  • Patent number: 8114925
    Abstract: A method for preparing a filler composition useful for preparing a nanocomposite polymer is provided. The method includes a first step of dispersing a water dispersible filler material in a liquid comprising water to form a dispersion and a second step of replacing at least a portion of the water of the liquid with an organic solvent. The resulting filler composition features a water concentration of the liquid of less than six percent by weight, and the average size of at least one dimension of the filler material is less than two hundred nanometers upon examination by transmission electron microscopy of a representative freeze dried sample of the dispersion of the first step. A nanocomposite polymer, particularly and epoxy resin composition, can be prepared by mixing the above-made filler composition with one or more polymer, polymer component, monomer or prepolymer.
