Patents by Inventor Kenneth J. Takeuchi

Kenneth J. Takeuchi 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: 11108036
    Abstract: This invention relates to the field of energy storage devices, and especially electrochemical energy storage devices where an electroactive moiety is chemically attached to a conductive polymer In particular, the invention relates to the design and fabrication of electrodes for the use in electrochemical storage devices having an electrochemically active conjugate. The electrochemically active conjugate preferably has an electroactive moiety selected from electroactive metal center, an electroactive organic species, or an electroactive non-metal species. Depending on the selected electroactive moiety, it can be attached either directly or through an appropriate linker to the conductive polymer.

  • Publication number: 20200185728
    Abstract: This invention relates to the field of energy storage devices, and especially electrochemical energy storage devices including electrolytes comprising an ionic liquid, one or more solvents, and one or more salts of a Group 2 element. Effects on electrochemical performance of the electrolyte of each of the components of the electrolyte were systematically determined. In addition, interactions between the electrolytes and separator films were dissected to optimize electrochemical performance of coin cell batteries.

  • Publication number: 20180261843
    Abstract: Bimetallic polyanionic materials, such as silver vanadium phosphorus oxide (Ag2VO2PO4, SVOP), are promising cathode materials for Li batteries due in part to their large capacity and high current capability. A new synthesis of Ag2VO2PO4 based on microwave heating is disclosed, where the reaction time is reduced by approximately 100 times relative to other reported methods, and the crystallite size is controlled via synthesis temperature, showing a linear positive correlation of crystallite size with temperature. Reaction times of an hour or less are sufficient to render phase-pure material after reaction at 50° C. to 180° C., significantly lower than the temperatures reported for other methods. Crystallite sizes between 42 nm and 60 nm are achieved by the novel method, smaller than by other methods. Silver/vanadium atomic ratios of 1.96 to 2.04 in the as-synthesized SVOP result and appear temperature-dependent.

  • Publication number: 20180226676
    Abstract: A novel silver-lithium-iodine solid-state energy device and system are disclosed. The rechargeable, self-assembled, dual-function, metal-iodide battery exhibits small size and high deliverable power. Inert until activation, the device may be stored for long periods of time. Upon activation, the device assembles the required electrochemical moieties for operation without external intervention. The device limits short-circuiting and self-discharge of the system by spontaneous reactions at the electrode/electrolyte interfaces, and thus is self-healing. By incorporating both silver and lithium in the same system, a dual function is achieved, whereby the characteristics of a lithium-based battery dominate at a low load and those of a silver-based battery dominate under a high load.
