The present invention provides an electrode and a method of preparing the same. The electrode of the present invention is prepared by forming a nanostructured conductor comprising a metal or metal oxide on a substrate and forming an active material comprising metal oxide nanoparticles on the surface of the nanostructured conductor. The electrode of the present invention can be used in various electrochemical devices such as energy storage devices including secondary batteries, supercapacitors, etc., photocatalyst elements, thermoelectric elements, or composite elements thereof. Moreover, the electrode of the present invention can be applied to a lithium secondary battery, in which intercalation/deintercalation of lithium ions is performed, and especially applied to a negative electrode of the lithium secondary battery. n The electrode of the present invention includes a substrate and an active material layer formed on the substrate, the active material layer including a nanostructured conductor formed on the substrate and comprising a metal or metal oxide and an active material formed on the surface of the nanostructured conductor and comprising metal oxide nanoparticles. |
