摘要： The present disclosure sets forth battery components for secondary and/or traction batteries. Described herein are new solid-state lithium (Li) conducting electrolytes including monolithic, single layer, and bi-layer solid-state sulfide-based lithium ion (Li+) conducting catholytes or electrolytes. These solid-state ion conductors have particular chemical compositions which are arranged and/or bonded through both crystalline and amorphous bonds. Also provided herein are methods of making these solid-state sulfide-based lithium ion conductors including new annealing methods. These ion conductors are useful, for example, as membrane separators in rechargeable batteries.

These engineered surfaces have a list of advantageous properties including, but not limited to, low surface area resistance, high Li+ ion conductivity, low tendency for lithium dendrites to form within or thereupon when the electrolytes are used in an electrochemical cell. Other advantages include voltage stability and long cycle life when used in electrochemical cells as a separator or a membrane between the positive and negative electrodes. Also set forth herein are methods of making these electrolytes including, but not limited to, methods of annealing these electrolytes under controlled atmosphere conditions. Set forth herein, additionally, are methods of using these electrolytes in electrochemical cells and devices. The instant disclosure further includes electrochemical cells which incorporate the lithium-stuffed garnet electrolytes set forth herein.

摘要： The instant disclosure sets forth multiphase lithium-stuffed garnet electrolytes having secondary phase inclusions, wherein these secondary phase inclusions are material(s) which is/are not a cubic phase lithium-stuffed garnet but which is/are entrapped or enclosed within a lithium-stuffed garnet. When the secondary phase inclusions described herein are included in a lithium-stuffed garnet at 30-0.1 volume %, the inclusions stabilize the multiphase matrix and allow for improved sintering of the lithium-stuffed garnet. The electrolytes described herein, which include lithium-stuffed garnet with secondary phase inclusions, have an improved sinterability and density compared to phase pure cubic lithium-stuffed garnet having the formula Li7La3Zr2O12.
