  • SILICON OXIDE FOR ANODE ACTIVE MATERIAL OF SECONDARY BATTERY
    Publication number: 20140106221
    Abstract: Provided is silicon oxide for an anode active material of a secondary battery. More particularly, the present invention provides silicon oxide included in an anode active material of a secondary battery, wherein a ratio of a maximum height (h2) of a peak in a 2 theta range of 40° to 60° to a maximum height (h1) of a peak in a 2 theta range of 15° to 40° in a X-ray diffraction (XRD) pattern of the silicon oxide satisfies 0.40?h2/h1?1.5.

  • GRAPHENE/METAL NANOCOMPOSITE POWDER AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20110256014
    Abstract: Graphene/metal nanocomposite powder and a method of preparing the same are provided. The graphene/metal nanocomposite powder includes a base metal and graphenes dispersed in the base metal. The graphenes act as a reinforcing material for the base metal. The graphenes are interposed as thin film types between metal particles of the base metal and bonded to the metal particles. The graphenes contained in the base metal have a volume fraction exceeding 0 vol % and less than 30 vol % corresponding to a limit within which a structural change of the graphenes due to a reaction between the graphenes is prevented.
