Niall Donnelly 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).

  • SOLID STATE LITHIUM-AIR BASED BATTERY CELL
    Publication number: 20150044581
    Abstract: In an example, the present invention provides a solid state battery device, e.g., battery cell or device. The device has a current collector region and a lithium containing anode member overlying the current collector region. The device has a thickness of electrolyte material comprising a first garnet material overlying the lithium containing anode member. The thickness of electrolyte material has a density ranging from about 80 percent to 100 percent and a porous cathode material comprising a second garnet material overlying the thickness of electrolyte material. The porous cathode material has a porosity of greater than about 30 percent and less than about 95 percent and a carbon bearing material overlying a surface region of the porous cathode material. In an example, the carbon bearing material comprises substantially carbon material, although there can be variations.
