摘要： An apparatus and method are provided for manufacturing an electrode of hydrous ruthenium oxide thin film, consisting of an injector for spraying a precursor solution, a substrate for depositing the precursor solution, a base for supporting the substrate and a halogen lamp for heating the substrate, a DC power supply connected to the injector and base, a space adjuster for adjusting the spraying space between the injector and the base, and temperature controller for controlling the temperature of the base. Because of the strong electric field, the sprayed ruthenium precursor solution atomizes the nano-sized very fine particles. Therefore, the atomized particles are deposited on the substrate to form a very fine porous thin film under the influence of electrically charged molecular actions without the influence of gravitation force. The ruthenium oxide electrode formed the fine porous thin film has excellent property of super capacitor, composite electrode of ruthenium oxide and activated carbon.

摘要： The present invention provides an asymmetric hybrid capacitor, in which metal oxide containing lithium and capable of producing lithium ions by an electrochemical reaction and supplying the lithium ions in an electrolyte in the capacitor is used as a positive electrode active material, and metal oxide capable of accepting the lithium ions supplied through the electrolyte is used as a negative electrode active material, such that the lithium ions of the same participate in the electrochemical reactions at both electrodes. As a result, it is possible to minimize reduction in ionic conductivity during charge/discharge, compared with conventional asymmetric hybrid capacitors, in which metal oxide and a carbon material are used as electrode materials, respectively. Moreover, since metal oxide having high specific capacitance is used to form both electrodes, it is possible to maximize energy density and power density.

摘要： A method for the synthesis of nanocomposites is provided. The method comprises the steps of mixing carbon nanotubes with a urea solution to form urea/carbon nanotube composites (first step), mixing the urea/carbon nanotube composites with a solution of a metal oxide or hydroxide precursor to prepare a precursor solution (second step), and hydrolyzing the urea in the precursor solution to form a metal oxide or hydroxide coating on the carbon nanotubes (third step). Further provided are nanocomposites synthesized by the method. In the nanocomposites, a metal oxide or hydroxide is coated to a uniform thickness in the nanometer range on porous carbon nanotubes. Advantageously, the thickness of the coating can be easily regulated by controlling the urea content of urea/carbon nanotube composites as precursors. In addition, the nanocomposites are nanometer-sized powders and have high electrical conductivity and large specific surface area. Therefore, the nanocomposites are useful as electrode active materials for electrochemical capacitors, including pseudo capacitors and electrochemical double layer capacitors, lithium secondary batteries, and polymer batteries. Further provided is a capacitor comprising the nanocomposites.
