摘要： Provided herein are detect-free solid-state separators which are useful as Li| ion-conducting electrolytes in electro-chemical cells and devices, such as, but not limited to, rechargeable batteries. In some examples, the separators have a Li+ ion-conductivity greater than 1*10−3 S/cm at room temperature.

摘要： 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 Li+ ions. 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.

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.
