  • Patent number: 7316867
    Abstract: A thin film for an anode of a lithium secondary battery having a current collector and an anode active material layer formed thereon is provided. The anode active material layer is a multi-layered thin film formed by stacking a silver (Ag) layer and a silicon-metal (Si-M) layer having silicon dispersed in a base made from metal reacting with silicon while not reacting with lithium. The cycle characteristic of the thin film for an anode can be improved by suppressing the volumetric expansion and shrinkage of Si occurring during charging/discharging cycles. Thus, a lithium secondary battery with improved life characteristics by employing the thin film for an anode, which greatly improves the chemical, mechanical stability of the interface between an electrode and an electrolyte.

  • Publication number: 20070279562
    Abstract: An alignment layer for an LCD includes a thin layer of silicon oxide SiOx. The silicon oxide layer horizontally aligns liquid crystals thereon when the value of x is in the range from about 1.0 to about 1.5, but vertically aligns the liquid crystals when the value of x is in a range from about 1.5 to about 2.0. The alignment layer is readily formed on a large area of the substrate through chemical vapor deposition or evaporation deposition. Because the alignment layer is thermally and physically stable, the operational characteristics of the liquid crystal display employing this alignment layer are improved. In addition, the alignment layer has a thickness of about 500 to about 3000 angstroms thereby improving light transmittance of the LCD having the alignment layer.
