Patents by Inventor Laurie I. Jegaden

Laurie I. Jegaden 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 manganese oxide compositions
    Patent number: 10522822
    Abstract: The present disclosure relates to improved LMO composition suitable for use as cathode material in rechargeable lithium ion batteries. The LMO composition may be doped with an additional metal or undoped. The LMO composition carries a surface treatment of LiF that protects the LMO from acid degradation. Cathodes prepared from the improved LMO have improved fade characteristics.
    Type: Grant
    Filed: February 1, 2013
    Date of Patent: December 31, 2019
    Assignee: EMD Acquisition LLC
    Inventors: Phillip M. Story, Laurie I. Jegaden
  • Method for preparing electrolytic manganese dioxide
    Patent number: 10109858
    Abstract: Disclosed herein is an improved cathode material prepared from high purity electrolytic manganese dioxide. Also disclosed is a method for preparing high purity MnO2 and converting MnO2 particles to Mn2O3.
    Type: Grant

  • Removal of organic impurities from water
    Patent number: 9422177
    Abstract: The present disclosure relates to the hydrostatic testing of pipelines and to purification of waste water from such testing. More specifically, there is provided a method of hydrostatically pressure testing a natural gas pipeline using water. The waste water, which is contaminated with hydrocarbons, is subsequently treated by contacting it with manganese dioxide so that the hydrocarbons are broken down into carbon dioxide and water.
