Patents by Inventor Vinay Ishwar Hegde

Vinay Ishwar Hegde 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).

  • Patent number: 11404719
    Abstract: Materials for coating a metal anode in a high energy battery, anodes coated with the materials, and batteries incorporating the coated anodes are provided. Also provided are batteries that utilize the materials as electrolytes. The coatings, which are composed of binary, ternary, and higher order metal and/or metalloid oxides, nitrides, fluorides, chlorides, bromides, sulfides, and carbides limit the reactions between the electrolyte and the metal anode in a battery, thereby improving the performance of the battery, relative to a battery that employs a bare anode.
    Type: Grant
    Filed: September 28, 2020
    Date of Patent: August 2, 2022
    Assignee: Northwestern University
    Inventors: Vinay Ishwar Hegde, David H. Snydacker, Christopher M. Wolverton

  • Patent number: 10374262
    Abstract: Cathode coatings for lithium ion batteries, cathodes coated with the coatings, and lithium ion batteries incorporating the coated cathodes are provided. The coatings, which are composed of binary, ternary, and higher order metal oxides and/or metalloid oxides, can reduce the hydrofluoric acid (HF)-induced degradation of the electrolyte and/or cathodes, thereby improving the performance of lithium ion batteries, relative to lithium ion batteries that employ bare cathodes.

  • Patent number: 10322950
    Abstract: Methods for extracting lithium from solutions containing lithium ions via reversible cation exchange with H+ are provided. The methods utilize metal oxide or metalloid oxide cation exchange materials having an active sublattice that preferentially bind Li+ cations, relative to both H+ and Na+, in a sample solution and preferentially bind H+, relative to Li+, in an acidic solution.
