  • Patent number: 8211572
    Abstract: Disclosed is a fabrication method for an electrode active material, and a lithium battery comprising an electrode active material fabricated therefrom. The fabrication method for an electrode active material comprises preparing an aqueous solution by dissolving a precursor that can simultaneously undergo positive ion substitution and surface-reforming processes in water; mixing and dissolving raw materials for an electrode active material with a composition ratio for a final electrode active material in the aqueous solution, thereby preparing a mixed solution; removing a solvent from the mixed solution, thereby forming a solid dry substance; thermal- processing the solid dry substance; and crushing the thermal-processed solid dry substance.

  • Publication number: 20120107224
    Abstract: Methods to at least partially reduce a niobium oxide are described wherein the process includes mixing the niobium oxide and niobium powder to form a powder mixture that is then heat treated to form heat treated particles which then undergo reacting in an atmosphere which permits the transfer of oxygen atoms from the niobium oxide to the niobium powder, and at a temperature and for a time sufficient to form an oxygen reduced niobium oxide. Oxygen reduced niobium oxides having high porosity are also described as well as capacitors containing anodes made from the oxygen reduced niobium oxides.

  • Patent number: 8137654
    Abstract: Provided is a roasting method capable of reducing both C and S components in minerals down to 0.5% or less, respectively, and securing a yield ratio of 90% or more for the Mo component. In a rotary kiln 7, a V, Mo and Ni containing material containing C and S components is subjected to oxidizing roasting to remove the C and S components from the material before reducing the material by means of a reducing agent in order to recover valuable metals composed of V, Mo and Ni. The rotary kiln is equipped with a burner 11 disposed on a material charge side 8a of the roasting furnace 8 to which the material is charged. In the roasting furnace, a direction along which the material moves and a flow of oxygen-containing gas introduced into the roasting furnace 8 are set to be parallel with each other.

  • Publication number: 20120040192
    Abstract: The present invention provides a method to effectively inhibit the oxidization of VO(acac)2 in solution for months. It is believed that VO(acac)2 forms a ?-complex with as many as three allylic alcohols which precludes reaction with any oxygen in the system. Although saturated and homo-allylic alcohols were also tested, this effect appears only in the allylic-alcohol based solutions. This ability to inhibit oxidation of VO(acac)2 allows these solutions to be used for making thermochromic VO2 film much more easily and economically as it avoids the requirement of operating under low oxygen level conditions. Thus the present invention provides a method of stabilizing vanadium oxyacetylacetonate (VO(acac)2) in solution against oxidation for extended periods of time, comprising the steps of mixing the oxyacetylacetonate precursor in an allylic alcohol prior to spin-coating for VO2 film formation. The allylic alcohol may be (?-methallyl alcohol.
