  • Metal sulfide filled carbon nanotubes and synthesis methods thereof
    Patent number: 11932966
    Abstract: Filled carbon nanotubes (CNTs) and methods of synthesizing the same are provided. An in situ chemical vapor deposition technique can be used to synthesize CNTs filled with metal sulfide nanowires. The CNTs can be completely and continuously filled with the metal sulfide fillers up to several micrometers in length. The filled CNTs can be easily collected from the substrates used for synthesis using a simple ultrasonication method.
    Type: Grant
    Filed: January 6, 2023
    Date of Patent: March 19, 2024
    Assignee: THE FLORIDA INTERNATIONAL UNIVERSITY BOARD OF TRUSTEES
    Inventors: Wenzhi Li, Yuba Poudel

  • Filled carbon nanotubes and methods of synthesizing the same
    Patent number: 11417885
    Abstract: Filled carbon nanotubes (CNTs), methods of synthesizing the same, and lithium-ion batteries comprising the same are provided. In situ methods (e.g., chemical vapor deposition techniques) can be used to synthesize CNTs (e.g., multi-walled CNTs) filled with metal sulfide nanowires. The CNTs can be completely (or nearly completely) and continuously (or nearly continuously) filled with the metal sulfide fillers up to several micrometers in length. The filled CNTs can be synthesized on a carbon substrate. A lithium-ion battery can comprise a cathode, an anode comprising filled CNTs as described herein, and an electrolyte in contact with the cathode and/or the anode.
