Garnet materials for Li secondary batteries and methods of making and using garnet materials
First Claim
1. A method for making a lithium-stuffed garnet thin film, the method comprising:
- providing a mixture comprising lithium-stuffed garnet or lithium-stuffed garnet chemical precursors;
providing a slurry comprising the mixture and a solvent;
depositing the slurry onto a substrate to form a film; and
sintering the film between and in direct contact with setter plates to form a lithium-stuffed garnet thin film.

Abstract
Set forth herein are garnet material compositions, e.g., lithium-stuffed garnets and lithium-stuffed garnets doped with alumina, which are suitable for use as electrolytes and catholytes in solid state battery applications. Also set forth herein are lithium-stuffed garnet thin films having fine grains therein. Disclosed herein are novel and inventive methods of making and using lithium-stuffed garnets as catholytes, electrolytes and/or anolytes for all solid state lithium rechargeable batteries. Also disclosed herein are novel electrochemical devices which incorporate these garnet catholytes, electrolytes and/or anolytes. Also set forth herein are methods for preparing novel structures, including dense thin (<50 um) free standing membranes of an ionically conducting material for use as a catholyte, electrolyte, and, or, anolyte, in an electrochemical device, a battery component (positive or negative electrode materials), or a complete solid state electrochemical energy storage device. Also, the methods set forth herein disclose novel sintering techniques, e.g., for heating and/or field assisted (FAST) sintering, for solid state energy storage devices and the components thereof.
