  • Patent number: 11688856
    Abstract: The present invention relates to an electrode structure for a secondary battery comprising a potential sheath capable of suppressing a side reaction between an electrode and an electrolyte through electric potential control, and a method for manufacturing the same. The electrode structure for the secondary battery according to the present invention uses the electric potential control so that an unstable SEI layer, which causes decrease in cycle characteristic and capacity of an anode material, occurs only on the surface of a potential sheath without occurring on the surface of the anode active material, thereby being capable of completely solving the problems of the existing nanostructured electrode.

  • Publication number: 20060189018
    Abstract: A heterojunction structure composed of a p-type semiconductor thin film and n-type ZnO-based nanorods epitaxially grown thereon exhibits high luminescence efficiency property due to facilitated tunneling of electrons through the nano-sized junction and the use of ZnO having high exciton energy as a light emitting material, and thus it can be advantageously used in nano-devices such as LED, field effect transistor, photodetector, sensor, etc.
