Display structures and methods of manufacture of display structure including a display panel with a curved three-dimensional film contour are described. In an embodiment, a display panel includes display area with a main body area and a plurality of petals extending from the main body area. The petals are folded into a curved three-dimensional (3D) film contour, and are separated by corresponding trenches between petals. The trenches may be filled with various seam hiding materials to visually obscure the trenches.

Display structure for electronic devices

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.

Translucent and transparent separators

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.

Lithium, phosphorus, sulfur, and iodine containing electrolyte and catholyte compositions, electrolyte membranes for electrochemical devices, and annealing methods of making these electrolytes and catholytes

Set forth herein are electrolyte compositions that include both organic and inorganic constituent components and which are suitable for use in rechargeable batteries. Also set forth herein are methods and systems for making and using these composite electrolytes.

Composite electrolytes

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.
