  • Patent number: 8848339
    Abstract: A capacitor and a manufacturing method thereof are provided. Two electrodes are disposed opposite to each other. Two electrode protection layers are respectively disposed on inner sides of the electrodes and include carbon particles each covered and bonded with a polymer shell. Active carbon layers are disposed on opposite inner sides of the electrode protection layers. The separator is disposed between the active carbon layers. The electrolyte fills between the electrode protection layers. The polymer shells of each electrode protection layer are bonded to the surface of the corresponding electrode by first and second functional groups. The first functional groups include thiol groups. The second functional groups include epoxy groups or carboxylic groups. The electrode protection layers serve as adhesion layers between the active carbon layers and the electrodes, and protect the electrodes from being corroded by the acid electrolyte solution.

  • Patent number: 8287753
    Abstract: A gel electrolyte composition is provided. The composition of the gel electrolyte includes an unsubstituted or substituted pyridine, a metal salt, a halogen molecule, an unsubstituted or substituted nicotinic acid and a solvent. The composition may be free from or substantially free from one or more of a polymer and a low molecular gelling agent. Also provided is a dye-sensitized solar cell containing the composition as well as a method for preparing the composition.

  • Publication number: 20060233462
    Abstract: A method and system are provided to identify coordinate information of a selected position on a three-dimensional object or on a leaf among plural pages with pre-formed reference indications. While identifying the coordinated information on the leaf, identification of page number is accomplished based on the reference indications formed around margins of the sheet. Moreover, by using at least one corner of the leaf and symbols printed around the margins as the reference coordinate data, the actual coordinate information of the selected position is derived. Corresponding to the actual coordinated information, accessory data in a form of voice, image or text are then output.
