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 Liions. 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.

Lithium-stuffed garnet electrolytes with a reduced surface defect density and methods of making and using the same

Provided herein are detect-free solid-state separators which are useful as Liion-conducting electrolytes in electro-chemical cells and devices, such as, but not limited to, rechargeable batteries. In some examples, the separators have a Liion-conductivity greater than 1*10S/cm at room temperature.
