Patent number: 12142754Abstract: A method of fabricating nanocomposite anode material embodying a lithium titanate (LTO)-multi-walled carbon nanotube (MWNT) composite intended for use in a lithium-ion battery includes providing multi-walled carbon nanotube (MWNTs), including nanotube surfaces, onto which functional oxygenated carboxylic acid moieties are arranged, generating 3D flower-like, lithium titanate (LTO) microspheres, including thin nanosheets and anchoring the acid-functionalized MWNTs onto surfaces of the 3D LTO microspheres by ?-? interaction strategy to realize the nanocomposite anode material.Type: GrantFiled: July 6, 2021Date of Patent: November 12, 2024Assignee: THE RESEARCH FOUNDATION FOR THE STATE UNIVERSITY OF NEW YORKInventors: Stanislaus Wong, Lei Wang, Coray McBean, Amy C.

Patent number: 12002921Abstract: 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.Type: GrantFiled: August 1, 2016Date of Patent: June 4, 2024Assignee: THE RESEARCH FOUNDATION FOR THE STATE UNIVERSITY OF NEW YORKInventors: Esther S. Takeuchi, Kenneth J. Takeuchi, Amy C. Marschilok

Publication number: 20240145679Abstract: A method of preparing a composition for use as a cathode that combines two different cathode materials is disclosed. When utilized in a battery, one cathode material is rechargeable, and the second cathode material has a high capacity with a lower voltage than the first cathode material. The active materials may be combined in several fashions including mixing, layering, deposition, coating, and/or patterning. Such batteries can be tested repeatedly over a specific voltage range and provide high capacity under full discharge at deployment.Type: ApplicationFiled: October 4, 2020Publication date: May 2, 2024Applicant: The Research Foundation for the State University of New YorkInventors: Esther S.

Patent number: 11909046Abstract: 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.Type: GrantFiled: March 7, 2018Date of Patent: February 20, 2024Assignee: THE RESEARCH FOUNDATION FOR THE STATE UNIVERSITY OF NEW YORKInventors: Kenneth J.

Patent number: 11349117Abstract: A method of synthesizing an electrode material for lithium ion batteries from Fe3O4 nanoparticles and multiwalled carbon nanotubes (MWNTs) to yield (Fe3O4-NWNTs) composite heterostructures. The method includes linking the Fe3O4 nanoparticles and multiwalled carbon nanotubes using a ?-? interaction synthesis process to yield the composite heterostructure electrode material. Since Fe3O4 has an intermediate voltage, it can be considered an anode (when paired with a higher voltage material) or a cathode (when paired with a lower voltage material).Type: GrantFiled: January 17, 2019Date of Patent: May 31, 2022Assignee: The Research Foundation for the State University of New YorkInventors: Stanislaus Wong, Lei Wang, Coray McBean, Amy C.

Publication number: 20110183215Abstract: A new cathode design is provided comprising a cathode active material mixed with a binder and a conductive diluent in at least two differing formulations. Each of the formulations exists as a distinct cathode layer. After each layer is pressed or sheeted individually, a first one of the layers is contacted to a current collector. The other layer is then contacted to the opposite side of the layer contacting the current collector. Therefore, by using electrodes comprised of layers, where each layer is optimized for a desired characteristic (i.e. high capacity, high power, high stability), the resulting battery will display improved function over a wide range of applications. Such an exemplary cathode is comprised of: SVO (100?x %)/SVO (100?y %)/current collector/SVO (100?y %)/SVO (100?x %), wherein x and y are different and represent percentages of non-active materials.Type: ApplicationFiled: April 2, 2007Publication date: July 28, 2011Applicant: Greatbatch Ltd.Inventors: Amy C.

Patent number: 7820328Abstract: An electrochemical cell comprising an electrode, whether it is the cathode of a primary cell or an anode or a cathode of a secondary cell, comprised of a mixture of a robust, high temperature binder along with a sacrificial decomposable polymer is described. The robust binder remains in the electrode throughout formation and processing, and maintains adhesion and cohesion of the cathode during utilization. The sacrificial decomposable polymer is present during the electrode formation stage. However, it is decomposed via a controlled treatment prior to electrode utilization. Upon subsequent high pressure pressing, the void spaces formerly occupied by the sacrificial polymer provides sites where the electrode active material collapses into a tightly compressed mass with enhanced particle-to-particle contact between the active material particles. For a cathode in a primary cell, for example a Li/SVO cell, the result is believed to be improved rate capability, capacity and stability throughout discharge.Type: GrantFiled: July 27, 2007Date of Patent: October 26, 2010Assignee: Greatbatch Ltd.Inventors: Esther S.
