Stephanie Wunder 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).

  • Anionic polymers, electrolytes comprising the same, and methods of manufacture thereof
    Patent number: 11923504
    Abstract: The invention provides a novel anionic polymer useful as a solid electrolyte in a lithium battery. The electrolyte matrix provides directional, flexible, polymeric ion channels with 100% lithium conduction with low-to-no affinity of the matrix for the lithium ion, in part due to the low concentration or absence of lone pair electrons in the anionic polymer.
    Type: Grant

    Date of Patent: March 5, 2024

  • Silanated silica-ceramic materials, and methods of making and using the same
    Patent number: 11387520
    Abstract: The invention provides a novel ceramic-metal oxide-polymer composite material. A functionalized metal oxide nanolayer coating can be bonded between LICGCs and polymers/oligomers, which protects the LICGC from corrosion, has a low interfacial resistance to Li+ migration, and can be a SIC. Hybrid ceramic-polymer electrolytes were formed by engineering the interface between a LICGC and a polymer, polyethylene oxide (PEO), by sputter coating a 200 nm thick SiO2 layer onto a lithium ion conducting glass ceramic (LICGC) and silanating the SiO2 with a functionalized PEG in the presence of LiTFSI. A low interfacial resistance (Rinterfacial) was measured, the same as that obtained for a SiO2 interface soaked with liquid tetraglyme/LiTFSI. The pegylated SiO2 interface (unlike the tetraglyme/LiTFSI interface) protected the LICGC from corrosion by Li0 metal. The (PEG-LiTFSI)—SiO2-LICGC could be bonded with polyethylene oxide/LiTFSI.

  • Multi-ionic salts and uses thereof
    Patent number: 10731010
    Abstract: The invention provides a novel composition comprising a multi-ionic polyoligomeric silsesquioxane and a polyether solvent, optionally with an additional lithium salt. The composition of the invention allows for improved lithium ion transference over lithium salts alone by avoiding the problem of ion aggregation that reduces conductivity in single ion conductors. Also provided is a method for forming such a composition and a liquid electrolyte comprising a multi-ionic polyoligomeric silsesquioxane and a polyether solvent, optionally with an additional lithium salt.
