Publication number: 20230387710Abstract: Described herein are methods and systems for controlling the charge and discharge characteristics of lithium-metal liquid-electrolyte (LiMLE) electrochemical cells that ensure extended cycle life even at high charge rates. In some examples, a method comprises charging a LiMLE electrochemical cell using a set of charge characteristics and discharging the cell using a set of discharge characteristics. These characteristics are specifically tailored to the cell design. For example, the cell temperature can be higher during the charge than during the discharge, especially for viscous electrolytes. For example, the cell can be heated before charging, e.g., using a separate heater and/or charge-discharge pulses (before or while charging the cell). In the same or other examples, the set of charge characteristics comprises charge pulses such that each pair of charge pulses is separated by a discharge pulse. The current during each discharge pulse can be greater during each charge pulse.Type: ApplicationFiled: May 31, 2023Publication date: November 30, 2023Applicant: Cuberg, Inc.Inventors: Jack Fawdon, Seamus Bannon, Nadine Kuhn, Stephen Lawes, Ali Hemmatifar, Richard Wang, Jeremy Gong, Eiara Fajardo, Kathryn Hicks

Publication number: 20230291061Abstract: Described herein are battery assemblies that comprise lithium-metal electrochemical cells and pressure-applying structures disposed adjacent to the cells and applying uniform pressure to the cells. Specifically, this uniform pressure is applied between a minimum threshold and a maximum threshold at any operating state of charge of these cells and, in some examples, over the entire operating lifetime of the cells. A pressure-applying structure can be positioned between a pair of adjacent cells or between a cell and an assembly enclosure. In some examples, the footprint of the pressure-inducing structure fully covers the footprint of the negative-electrode planar portion. The pressure-inducing structure may have a stress relaxation of less than 5% and/or a compression set of less than 10%. The pressure-inducing structure may remain in an elastic deformation region at any operating condition. In some examples, the pressure-inducing structure is foam or aerogel.Type: ApplicationFiled: March 8, 2022Publication date: September 14, 2023Applicant: Cuberg, Inc.Inventors: Seamus Bannon, Nadine Kuhn, Edward Meyjes, Stephen Lawes, Richard Wang, Chan Lojewski

In the same or other examples, a lithium-ejecta containment component can be integrated into the battery-assembly enclosure and/or cell enclosures. Furthermore, a lithium-ejecta containment component can be configured to absorb and contain the ejected lithium metal. In further examples, a lithium-ejecta containment component is configured to direct the ejected lithium metal away from the battery assembly.Type: ApplicationFiled: February 9, 2022Publication date: August 10, 2023Applicant: Cuberg, Inc.Inventors: Stephen Lawes, Edward Meyjes, Seamus Bannon, Alex Beraud, Luke Strohbehn, Richard Wang
