Patents by Inventor William Fitzhugh

William Fitzhugh 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: 11777138
    Abstract: The invention provides compositions containing a solid state electrolyte (SSE) containing an alkali metal and a sulfide for use as the electrolyte matrix in a solid state rechargeable battery. The SSE compositions may further contain phosphorous, silicon, or a dopant atom, such as a halogen. These compositions are advantageous as they use Earth-abundant elements, have high voltage stability, excellent battery cycle performance, and are fabricated and used under conditions that do not require excessive external pressures which would otherwise limit their use in a production battery. In particular, the SSEs have a controllable microstructure, e.g., core-shell structure, that enhances their inherent stability while obviating the need for excessively large pressures to control the electrolyte stability. Methods of producing the compositions and rechargeable batteries including the composition are also provided.

  • Publication number: 20210408580
    Abstract: The invention provides rechargeable batteries including a solid state electrolyte (SSE) containing an alkali metal disposed between two electrodes. The batteries are volumetrically constrained imparting increased stability under voltage cycling conditions, e.g., through microstructure mechanical constriction on the solid state electrolyte and the electrolyte-electrode interface. These batteries of the invention are advantageous as they may be all-solid-state batteries, e.g., no liquid electrolytes are necessary, and can achieve higher voltages with minimal electrolyte degradation.

  • Patent number: 10233083
    Abstract: Methods and systems for separating carbon nanotubes are provided. An exemplary method of separating semiconducting carbon nanotubes and metallic carbon nanotubes contained within a solution can include providing electromagnetic waves travelling in one or more resonance modes and scattering at least a portion of the electromagnetic waves to form an electric gradient with the scattered waves. The method can further include recycling at least a portion of the scattered waves to the one or more resonance modes and separating at least a portion of the semiconducting carbon nanotubes and the metallic carbon nanotubes using the electric gradient.

  • Publication number: 20120329561
    Abstract: A system and methods that enables the generation of avatars or art from users' own genetic information. Users may obtain their personal genomic information via direct-to-consumer (DTC) genotyping service or a full resequencing service. Users' genomic profile may be processed by a software algorithm that translates the genotypes into model phenotype descriptions based on a set of reconfigurable rules. Derived from the users' own DNA, phenotype descriptions may be used to create avatars that represent the users in online games and social media applications. Such phenotype descriptions can also be used to create games that are customized to the user, and to generate artwork.
