  • Publication number: 20140255603
    Abstract: A surface coating method and a method for reducing irreversible capacity loss of a lithium rich transitional oxide electrode are disclosed herein. In an example of the surface coating method, a dispersion of a lithium rich transitional oxide powder and an oxide precursor or a phosphate precursor in a liquid is formed. The liquid is evaporated. The forming and evaporating steps are carried out in the absence of air to prevent precipitation of the oxide precursor or the phosphate precursor. Hydrolyzation of the oxide precursor or the phosphate precursor is controlled under predetermined conditions, and an intermediate product is formed. The intermediate product is annealed to form an oxide coated lithium rich transitional oxide powder or the phosphate coated lithium rich transitional oxide powder.

  • Patent number: 8821966
    Abstract: A method for manufacturing an image display device includes the step of forming a cured resin layer by interposing a photo-curable resin composition between a protection member and a display-side panel including an image display unit and a frame member and then photo-curing the photo-curable resin composition, with the photo-curable resin composition being disposed across between the image display unit and the frame member. In the manufacturing method, a high-viscosity resin composition having a viscosity of 3000 mPa·s or more and 12000 mPa·s or less is used as the photo-curable resin composition. Alternatively, after a gap between the image display unit and the frame member is sealed with a sealing film, a photo-curable resin composition is interposed between the display-side panel and the protection member.
