Patents by Inventor Barrie Linton Davies

Barrie Linton Davies 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).

  • Lithium battery and electrode
    Patent number: 7029794
    Abstract: An electrode includes an electrically conductive matrix containing a disulfide group, wherein an S—S bond of the disulfide group is cleaved by electrochemical reduction and reformed by electrochemical oxidation. A plurality of carbon nanotubes are substantially disentangled and dispersed in the electrically conductive matrix. The electrode can be used as a cathode of a lithium battery. A method for producing disentangled carbon nanotubes includes the steps of: adding a plurality of aggregates of carbon nanotubes to a liquid; and providing sheer force (e.g. passing the liquid through a narrow gap at a high speed) onto the liquid for disentangling the aggregates of carbon nanotubes therein.
    Type: Grant
    Filed: May 1, 2001
    Date of Patent: April 18, 2006
    Assignee: Celanese Ventures GmbH
    Inventors: Shizuo Ogura, Hidehisa Mokudai, Makoto Murata, Barrie Linton Davies
