Patents by Inventor Wu Li

Wu Li 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).

  • Non-aqueous battery with novel lithium manganese oxide cathode
    Patent number: 5733681
    Abstract: Insertion compounds that are not stable in pure water can be prepared by an aqueous electrochemical method. The pH of the electrolyte and/or the concentration of ions of the inserted species must be sufficiently high to provide stability for the product compound. The method is useful for further lithiation of conventional lithium ion battery cathode materials.
    Type: Grant
    Filed: December 19, 1996
    Date of Patent: March 31, 1998
    Assignee: Moli Energy (1990) Limited
    Inventors: Wu Li, Jeffrey Raymond Dahn
