  • Carbon nanotube composite electrode and method for manufacturing the same
    Patent number: 9583231
    Abstract: Provided is a carbon nanotube composite electrode having carbon nanotubes which are firmly fixed to an electrode substrate so as to utilize the characteristics of the carbon nanotubes, and having the intrinsic electrode characteristics of carbon nanotubes. The carbon nanotube composite electrode has a surface layer containing a porous oxide material and carbon nanotubes on the surface of the electrode substrate, wherein the carbon nanotubes are generated from the porous oxide material, and at least some of the carbon nanotubes are electrically connected to the electrode substrate. The carbon nanotube composite electrode is firmly fixed to the electrode substrate, and has the intrinsic electrode characteristics of carbon nanotubes, and thus may preferably be used in applications for electrodes and the like in various electronic devices such as electrochemical sensors and batteries.
