Abstract
Set forth herein are processes for making lithium-stuffed garnet oxides (e.g., LiLaZrO, 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.
