摘要： Set forth herein are processes for making and using electrolytes (also known as catholytes when the electrolytes are mixed with cathode active materials) for a positive electrode of an electrochemical cell. The catholytes include additives that prevent surface fluorination of lithium-stuffed garnet solid-state separators in contact with the positive electrode. Also set forth herein are electrochemical devices which include the catholytes in addition to a lithium-stuffed garnet solid-state electrolyte separator.

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.
