Abstract: The present invention relates to a reduced-graphene-oxide/silicon-metal-particle composite, a method of manufacturing the composite and an electrode for a secondary battery including the composite. The method of manufacturing the reduced-graphene-oxide/silicon-metal-particle composite includes preparing a reduced-graphene-oxide dispersion solution by reducing graphene oxide formed through cation-pi interaction, preparing a reduced-graphene-oxide/silicon-metal-particle dispersion solution by mixing the reduced-graphene-oxide dispersion solution with silicon metal particles, and manufacturing a composite powder having a core-shell structure by drying the reduced-graphene-oxide/silicon-metal-particle dispersion solution. Thereby, reduced graphene oxide can be formed using the graphene oxide dispersion solution having few defects and high purity obtained through cation-pi interaction, and dried to afford a composite powder having a core-shell structure, which is applicable to an electrode for a secondary battery.

Abstract: Disclosed are a nanometal-nanocarbon hybrid material and a method of manufacturing the same, the method including modifying the surface of nanocarbon to introduce a functional group to conductive nanocarbon; mixing the surface-modified nanocarbon with an isocyanate-based compound and a pyrimidine-based compound and allowing them to react, thus forming a nanocarbon dispersion reactive to metal ions; adding the nanocarbon dispersion with a metal salt precursor, a reducing agent and a solvent, thus manufacturing nanometal particles; and separating a hybrid of the nanometal particles having the nanocarbon bound thereto. Thereby, nanocarbon is mixed with an isocyanate-based compound and a pyrimidine-based compound and then allowed to react, whereby the nanocarbon reactive with metal ions is used as an additive, thus obtaining a nanometal having a low-dimensional shape having less than three dimensions.

Abstract: A flexible dye-sensitized solar cell includes: a fiber layer formed of nanofibers; a conductive electrode layer formed on one side of the fiber layer; a photoelectrode layer formed on the conductive electrode layer; a counter electrode layer formed on the other side of the fiber layer; a sealing member for enclosing the fiber layer, the conductive electrode layer, the counter electrode layer and the photoelectrode layer therein so as to seal said layers from the outside; and an electrolyte infiltrated into the fiber layer. A cell body in which an electrode and a photoelectrode are formed on one surface of the fiber that contains an electrolyte therein and a counter electrode is formed on the other side of the fiber is sealed with a polymer film, thus forming a flexible solar cell having an excellent sealing structure for preventing the electrolyte from leaking out of the cell even when pressure is externally applied.
