Patent number: 11901506Abstract: The instant disclosure sets forth multiphase lithium-stuffed garnet electrolytes having secondary phase inclusions, wherein these secondary phase inclusions are material(s) which is/are not a cubic phase lithium-stuffed garnet but which is/are entrapped or enclosed within a lithium-stuffed garnet. When the secondary phase inclusions described herein are included in a lithium-stuffed garnet at 30-0.1 volume %, the inclusions stabilize the multiphase matrix and allow for improved sintering of the lithium-stuffed garnet. The electrolytes described herein, which include lithium-stuffed garnet with secondary phase inclusions, have an improved sinterability and density compared to phase pure cubic lithium-stuffed garnet having the formula Li7La3Zr2O12.Type: GrantFiled: March 30, 2022Date of Patent: February 13, 2024Assignee: QuantumScape Battery, Inc.Inventors: Larry Beck, Cheng-Chieh Chao, Lei Cheng, Niall Donnelly, William H.

Publication number: 20230106403Abstract: Methods and systems for providing controlling in a repeatable manner a plurality of anode-free or lithium metal cells in a power-supply system. The cells are connected in series in one or more high energy density hybrid modules connected in parallel. Each high energy density hybrid module includes a corresponding hybrid module controller (HMC) and has a corresponding bi-directional DC-DC-converter, and each cell of the plurality of cells is independently measurable by the HMC. The corresponding bi-directional DC-DC-converter is used to charge and discharge of the plurality of cells in a repeatable manner to be within a selected state of charge (SOC) range that corresponds to a defined cycle life and energy density requirement.Type: ApplicationFiled: September 30, 2022Publication date: April 6, 2023Inventors: Stephen Glazier, Larry Beck, Steven Kaye, Mujeeb Ijaz, Hezhen Xie, Yadong Huang
