摘要： Set forth herein are processes for making lithium-stuffed garnet oxides (e.g., Li7La3Zr2O12, also known as LLZO) that have passivated surfaces comprising a fluorinate and/or an oxyfluorinate species. These surfaces resist the formation of oxides, carbonates, hydroxides, peroxides, and organics that spontaneously form on LLZO surfaces under ambient conditions. Also set forth herein are new materials made by these processes.

摘要： 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.

摘要： Provided herein are rapid, high quality film sintering processes that include high-throughput continuous sintering of lithium-lanthanum zirconium oxide (lithium-stuffed garnet). The instant disclosure sets forth equipment and processes for making high quality, rapidly-processed ceramic electrolyte films. These processes include high-throughput continuous sintering of lithium-lanthanum zirconium oxide for use as electrolyte films. In certain processes, the film is not in contact with any surface as it sinters (i.e., during the sintering phase).

摘要： Methods and apparatus for fabricating separators for solid-state lithium metal batteries employ rapid thermal processing. Aspects include high temperature sintering. Temperatures, durations of heat application, and proximity of heating elements to materials undergoing sintering combine to provide separators with desirable physical characteristics, including porosity, in a batch process.

摘要： Set forth herein are electrochemical cells which include a negative electrode current collector, a lithium metal negative electrode, an oxide electrolyte membrane, a bonding agent layer, a positive electrode, and a positive electrode current collector. The bonding agent layer advantageously lowers the interfacial impedance of the oxide electrolyte at least at the positive electrode interface and also optionally acts as an adhesive between the solid electrolyte separator and the positive electrode interface. Also set forth herein are methods of making these bonding agent layers including, but not limited to, methods of preparing and depositing precursor solutions which form these bonding agent layers. Set forth herein, additionally, are methods of using these electrochemical cells.
