Jeffrey Gilbert Killian 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).

  • Electrochemical storage cell containing at least one electrode formulated from a phenylene-thienyl based polymer
    Patent number: 6120940
    Abstract: An electrochemical storage cell or battery including as at least one electrode at least one electrically conductive polymer, the polymer being poly(1,4-bis(2-thienyl)-3-fluorophenylene), poly(1,4-bis(2-thienyl)-2,5-difluorophenylene), poly(1,4-bis(2-thienyl)-2,3,5,6-tetrafluorophenylene), or poly(1,4-bis(2-thienyl)-benzene). These polymeric electrodes have remarkably high charge capacities, and excellent cycling efficiency. The provision of these polymeric electrodes further permits the electrochemical storage cell to be substantially free of metal components, thereby improving handling of the storage cell and obviating safety and environmental concerns associated with alternative secondary battery technology.
    Type: Grant
    Filed: October 30, 1997
    Date of Patent: September 19, 2000
    Assignee: The Johns Hopkins University
    Inventors: Theodore O. Poehler, Peter Searson, Jeffrey Gilbert Killian, Haripada Sarker, Jennifer Giaccai, Yosef Gofer
  • Electrochemical storage cell containing at least one electrode formulated from a fluorophenyl thiophene polymer
    Patent number: 5733683
    Abstract: An electrochemical storage cell or battery including as at least one electrode at least one electrically conductive polymer, the polymer being poly (3(2-fluorophenyl)thiophene), poly(3(3-fluorophenyl) thiophene), poly(3(2,4-fluorophenyl) thiophene), poly(3(3,4-difluorophenyl) thiophene), poly(3(3,5-difluorophenyl) thiophene), or poly(3(3,4,5-trifluorophenyl)thiophene). These polymeric electrodes have remarkably high charge capacities, and excellent cycling efficiency. The provision of these polymeric electrode further permits the electrochemical storage cell to be substantially free of metal components, thereby improving handling of the storage cell and obviating safety and environmental concerns associated with alternative secondary battery technology.
