  • Nickel hydroxide, positive electrode material, alkaline battery, and method of producing nickel hydroxide
    Patent number: 11682761
    Abstract: A nickel hydroxide includes stacked nickel hydroxide layers. Each of the nickel hydroxide layers includes Ni2+ and OH?. At least one of the nickel hydroxide layers further includes a type of polyatomic anions. The polyatomic anions include a type of anions that are not SO42? or CO32?.
    Type: Grant
    Filed: June 26, 2020
    Date of Patent: June 20, 2023
    Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, NATIONAL RESEARCH COUNCIL OF CANADA

  • Platinum based nano-size catalysts
    Patent number: 7566681
    Abstract: The synthesis of Pt and PtRu and other Pt based nano-particles that catalyze the electrochemical oxidation of methanol, carbon monoxide and hydrogen, as well as oxygen reduction, is described. The Pt based catalysts are synthesized in solution forming particles of 0.8 to 10 nm size (forming a “colloidal” solution) and are subsequently applied to a desired substrate as e.g., carbon black, graphite, metals. The application of the nano-sized catalyst particles on the substrates involves electroless deposition at open-circuit, such as immersing the substrate into the colloidal solution or spraying the catalyst particles on the substrate. The Pt, PtRu and other Pt based catalyst can also be directly deposited on the substrate involving the simultaneous reduction and deposition of the Pt based catalysts onto the substrate surface and into its porous structure.
