  • Patent number: 10189719
    Abstract: An improved process is provided for forming a precursor to a lithium metal oxide. An improved lithium metal oxide formed by calcining the precursor is also provided. The process includes providing lithium bicarbonate in a first aqueous mixture. The lithium bicarbonate is then reacted with metal acetate thereby forming a second aqueous mixture comprising metal carbonate, lithium acetate, acetic acid and water wherein the acetic acid is neutralized with lithium hydroxide thereby forming a first mixture comprising metal carbonate and lithium acetate. The first mixture is separated into a second mixture and a third mixture wherein the second mixture comprises the metal carbonate and a first portion of lithium acetate with metal carbonate and lithium acetate being in a predetermined molar ratio. The third mixture comprises a second portion of lithium acetate. The second mixture is dried thereby forming the precursor comprising metal carbonate and lithium acetate in the predetermined molar ratio.

  • Patent number: 6248262
    Abstract: Carbon fiber-filled, thermoplastic resin compositions having improved electrical properties at a given level of carbon fibers are formed from thermoplastic resin and carbon fibers associated into bundles with a binder. The thermoplastic resin and the binder are selected to be incompatible such that the adhesion of the fiber to the resin is poor. An exemplary composition is formed from a thermoplastic polymer selected from among polystyrene, high impact polystyrene, polycarbonate, polybutylene terephthalate, polyethylene terephthalate, polyphenylene ether, polyether imide and blends thereof; and carbon fibers associated into bundles with a polyamide terpolymer binder. The bundles are dispersed within the thermoplastic polymer. The compositions can be used for injection molding of articles for use as components in applications requiring static dissipation and/or EMI shielding. Such articles include electronic devices, dust handling equipment and notebook computer enclosures.
