Patents by Inventor Arthur Driedger

Arthur Driedger 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-air cell protective membranes comprising polytetrafluoroethylene coated fiberglass cloth
    Publication number: 20110177401
    Abstract: Advanced lithium-air semi-fuel cell with non-aqueous electrolyte solution is provided, having higher energy density over the prior art cells, due to its protective, oxygen selective, permeable membrane of PTFE coated fiberglass cloth, placed over the cathode outer surface. Said membrane is flexible and protects the cell from moisture and evaporation of said electrolyte, which substantially minimizes parasitic losses of lithium and increases the cell efficiency and safety. The membrane may also have a layer of air-permeable adhesive added, facing said cathode.
    Type: Application
