  • Publication number: 20120015245
    Abstract: A shiny is manufactured using a low-molecular-weight organic acid as a dispersant and a nonaqueous organic solvent as a solvent, whereby a coated electrode for a power storage device in which an active material which has been made into microparticles each having a particle diameter of 100 nm or less is uniformly dispersed can be manufactured. By the use of the coated electrode manufactured in this manner, a power storage device with high charge/discharge characteristics can be manufactured. In other words, a power storage device with high capacity density can be realized because the amount of impurities is small and the power density is high due to the sufficient dispersion of the active material in the active material layer.

    Abstract: The invention provides a new route for the synthesis of carbon-coated powders having the olivine or NASICON structure, which form promising classes of active products for the manufacture of rechargeable lithium batteries. Carbon-coating of the powder particles is necessary to achieve good performances because of the rather poor electronic conductivity of said structures. For the preparation of coated LiFePO4, sources of Li, Fe and phosphate are dissolved in an aqueous solution together with a polycarboxylic acid and a polyhydric alcohol. Upon water evaporation, polyesterification occurs while a mixed precipitate is formed containing Li, Fe and phosphate. The resin-encapsulated mixture is then heat treated at 700° C. in a reducing atmosphere. This results in the production of a fine powder consisting of an olivine LiFePO4 phase, coated with conductive carbon.

  • Publication number: 20110183067
    Abstract: The present invention relates to an apparatus and method for coating carbon nano tubes, which is capable of coating carbon nano tubes on a film at the same time when the carbon nano tubes are produced, unlike a wet method, thereby reducing the number of processes and costs and improving performance. The apparatus and method has an advantage of directly applying a CNT-containing gas obtained by thermal chemical vapor deposition to a film to obtain a CNT coating film with the reduced numbers of processes and high quality through improvement of an electrical property by maintenance of dispersibility and CNT length, as compared to a conventional wet process.

  • Publication number: 20110165447
    Abstract: The printed battery has cathode and anode electrodes with terminals to connect to an external circuit, separator therebetween and electrolyte. An anode electrode material is applied on one side of the separator and a cathode electrode material on the opposite side. The anode material is dry and hydrophobic and is prepared by providing an anode active material, conductive material, solvent and a binder that are mixed to form an anode ink. The anode ink is applied on a substrate and then dried. In response to the drying, the solvent evaporates and the anode ink forms a film on the substrate. The prepared anode material is applied on the separator. An electrolyte solution is printed on the separator that has the anode material thereon. A cathode material is applied between a collector material and separator.
