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: 11749797Abstract: A fluoride shuttle (F-shuttle) battery and nanostructures of copper based cathode materials in the fluoride shuttle battery. The F-shuttle batteries include a liquid electrolyte, which allows the F-shuttle batteries to operate under room temperature. The minimum thickness of copper layer within the copper nanostructures is no more than 20 nm. The thickness of copper layer within the copper nanostructures is controlled and reduced to ensure the energy densities of F-shuttle batteries.Type: GrantFiled: June 18, 2019Date of Patent: September 5, 2023Assignees: HONDA MOTOR CO., LTD., CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Qingmin Xu, Christopher J.
