Publication number: 20250149655Abstract: The disclosure herein relates to rechargeable batteries and solid electrolytes therefore which include lithium-stuffed garnet oxides, for example, in a thin film, pellet, or monolith format wherein the density of defects at a surface or surfaces of the solid electrolyte is less than the density of defects in the bulk. In certain disclosed embodiments, the solid-state anolyte, electrolyte, and catholyte thin films, separators, and monoliths consist essentially of an oxide that conducts Li+ ions. In some examples, the disclosure herein presents new and useful solid electrolytes for solid-state or partially solid-state batteries. In some examples, the disclosure presents new lithium-stuffed garnet solid electrolytes and rechargeable batteries which include these electrolytes as separators between a cathode and a lithium metal anode.Type: ApplicationFiled: January 8, 2025Publication date: May 8, 2025Inventors: David CAO, Cheng-Chieh CHAO, Zhebo CHEN, Lei CHENG, Niall DONNELLY, Wes HERMANN, Timothy HOLME, Tommy HUANG, Kian KERMAN, Yang LI, Harsh MAHESHWARI

Patent number: 9960458Abstract: Provided are battery systems having multiple independently controlled sets of battery cells and method of using these systems to power, for example, drive trains of electric and hybrid vehicles. A battery system includes two or more sets of battery cells. Each set can be discharged and/or charged independently of another set based on different factors, such as a current power demand, power output capabilities of each set, and other like factors. One or multiple sets can be used to deliver power at any given time. In some embodiments, one set may be used to charge another set in the same power system. The same or different types of battery cells may be used in different sets. For example, one set may have battery cells having a higher power output capability, while another set may have battery cells with a higher energy density.Type: GrantFiled: April 29, 2016Date of Patent: May 1, 2018Assignee: QuantumScape CorporationInventors: Phil Weicker, Brian Pevear, Jay Underwood, Tim Holme, Wes Hermann
