Patent number: 11881581Abstract: The present disclosure relates to a method of making core-shell and yolk-shell nanoparticles, and to electrodes comprising the same. The core-shell and yolk-shell nanoparticles and electrodes comprising them are suitable for use in electrochemical cells, such as fluoride shuttle batteries. The shell may protect the metal core from oxidation, including in an electrochemical cell. In some embodiments, an electrochemically active structure includes a dimensionally changeable active material forming a particle that expands or contracts upon reaction with or release of fluoride ions. One or more particles are at least partially surrounded with a fluoride-conducting encapsulant and optionally one or more voids are formed between the active material and the encapsulant using sacrificial layers or selective etching. When the electrochemically active structures are used in secondary batteries, the presence of voids can accommodate dimensional changes of the active material.Type: GrantFiled: December 3, 2021Date of Patent: January 23, 2024Assignees: HONDA MOTOR CO., LTD., CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Nam Hawn Chou, Kaoru Omichi, Ryan McKenney, Qingmin Xu, Christopher Brooks, Simon C.

Patent number: 11437641Abstract: Redox flow battery efficiency and performance may be improved with a high energy density bipyridinium based ionic room-temperature liquid electrolyte. Current electrolytes require solvent to dissolve the redox-active material and a supporting electrolyte to maintain charge balance. A room temperature redox-active electrolyte having intrinsic charge balancing would not need a solvent to form a liquid and would therefore have a higher density of anions and cations involved with charge storage. As such, creating redox-active bipyridinium core ionic materials that are in a liquid form at room temperature or, more particularly, are liquids across the range at which a redox flow battery would operate permit smaller and less costly flow battery design than conventional flow batteries.Type: GrantFiled: December 16, 2020Date of Patent: September 6, 2022Assignee: Phillips 66 CompanyInventors: James A. Suttil, Sharmila Samaroo, Neal D. McDaniel, Jeffrey H. Drese, Hongjin Tan

Patent number: 11276855Abstract: Redox flow battery performance may be improved with a metal containing ionic liquid as a liquid electrolyte. Metal containing ionic liquids are liquids at all temperatures of interest and therefore do not need dilution. As such, voltage separation between the anolyte and catholyte may exceed 0.5 V and therefor rival current state-of-the-art energy storage technologies and with higher voltage separation may attain energy densities above 100 Wh/L.Type: GrantFiled: June 18, 2020Date of Patent: March 15, 2022Assignee: Phillips 66 CompanyInventors: James Anthony Suttil, Sharmila K.

Patent number: 11251457Abstract: A redox flow battery is described that does not include an ion exchange resin such as a proton exchange membrane but rather uses a generally stationary separator liquid that separates the anolyte from the catholyte at immiscible liquid-liquid interfaces. Solvents and electrochemically active components of the anolyte and catholyte would not cross the liquid-liquid interfaces between the separator liquid and the anolyte and catholyte, but certain ions in each of the anolyte and catholyte would cross the interface during charging and discharging of the redox flow battery. The separator liquid comprises a relatively small total volume of liquid in such a flow battery arrangement as compared to the anolyte and catholyte. Suitable chemical options are described along with system options for utilizing immiscible phases.Type: GrantFiled: September 20, 2019Date of Patent: February 15, 2022Assignee: Phillips 66 CompanyInventors: James Anthony Suttil, Hongjin Tan, Neal McDaniel, Sharmila Samaroo, Jeffrey H.

Patent number: 11050075Abstract: In some variations, a hydrogen-storage material formulation comprises: a solid hydrogen-storage material containing at least one metal and hydrogen that is bonded with the metal; and a liquid electrolyte that is ionically conductive for at least one ion derived from the hydrogen-storage material. The liquid electrolyte may be from 5 wt % to about 20 wt % of the hydrogen-storage material formulation, for example. Many materials are possible for both the hydrogen-storage material as well as the liquid electrolyte. The hydrogen-storage material has a higher hydrogen evolution rate in the presence of the liquid electrolyte compared to a hydrogen-storage material without the liquid electrolyte. This is experimentally demonstrated with a destabilized metal hydride, MgH2/Si system, incorporating a LiI—KI—CsI ternary eutectic salt as the liquid electrolyte. Inclusion of the liquid electrolyte gives a ten-fold increase in H2 evolution rate at 250° C., reaching 3.5 wt % hydrogen released in only 7 hours.Type: GrantFiled: March 22, 2018Date of Patent: June 29, 2021Assignee: HRL Laboratories, LLCInventors: John J.
