Takenori NISHIKATA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrode material including small diameter, carbon nanotubes bridging large diameter carbon nanotubes, redox flow battery electrode, redox flow battery, and method for producing electrode material
    Patent number: 11043680
    Abstract: A redox flow battery includes: first carbon nanotubes having an average diameter of 100 nm or r core, and second carbon nanotubes having an average diameter of 30 nm or less, in which the second carbon nanotubes are adhered to surfaces of the first carbon nanotubes such that the second carbon nanotubes bridge between the plural first carbon nanotubes. Since the redox flow battery includes an electrode material and an electrode including the electrode material, the electromotive force and the charging capacity are high.
    Type: Grant
    Filed: November 11, 2014
    Date of Patent: June 22, 2021
    Assignee: SHOWA DENKO K.K.
    Inventors: Kenzo Hanawa, Ryuji Monden, Takenori Nishikata
