  • Positive electrode active material particle including core containing lithium cobalt oxide and shell containing composite metal oxide and preparation method thereof
    Patent number: 11942632
    Abstract: A positive electrode active material particle includes a core that contains lithium cobalt oxide represented by the following Chemical Formula LiaCo(1-x)MxO2-yAy and a shell that is coated on the surface of the core and contains composite metal oxide of a metal with an oxidation number of +2 and a metal with an oxidation number of +3. In particular, M is at least one selected from the group consisting of Ti, Mg, Zn, Si, Al, Zr, V, Mn, Nb and Ni. A is oxygen-substitutional halogen and 1.00?a?1.05, 0?x?0.05, and 0?y?0.001.

  • Expandable starch beads and method for preparing the same
    Patent number: 9018268
    Abstract: Provided is expandable starch beads including a starch-monomer copolymer and a foaming agent impregnated in the starch-monomer copolymer, in which the starch-monomer copolymer is prepared by bonding at least one monomer selected from the group consisting of styrene, ?-methylstyrene, lactide, lactic acid, acrylic acid, methacrylic acid, acrylic ester, methacrylic ester, acrylonitrile, acrylamide, and caprolactone to starch, and the foaming agent includes at least one selected from the group consisting of C2 to C7 aliphatic hydrocarbon, C2 to C7 halogenated hydrocarbon, and carbon dioxide. Since the expandable starch beads have the similar properties to expandable polystyrene beads, and thereby can be foam-molded by equipment for foaming the expandable polystyrene beads, it is possible to produce foams with various sizes and various shapes.
