Abstract: A quantum dot-based color display includes a backlight unit with a light source and light source distribution layer and a photo down-conversion light emissive layer. The photo down-conversion layer has populations of light-emitting Group II-VI core-shell structure quantum dots, the core having an excess amount of a Group II component in a ratio to a Group VI component of approximately 6:1 or greater. The quantum dots include an organic fraction of approximately 20 weight percent to approximately 45 weight percent, the organic fraction including ligands bound to quantum dot surfaces in an as-deposited state and including one or more long-chain fatty acids. Non-barrier polymer films are positioned on either side of the photo down conversion light emissive layer which exhibits photo stability at a light intensity of at least 4000 W/m2. A display panel cooperates with the back light unit to form the display.

Abstract: The preset invention provides an electrode structure for a lithium ion battery comprising an electrode selected from a cathode including a lithium-based material or an anode including a conductive material, and a melt-convertible encapsulation layer covering at least one surface layer of the electrode. The melt-convertible encapsulation layer comprises a network of nanofibers having the diameter ranging approximately from 100 to 300 nm and polymer microspheres embedded in and coated on the nanofibrous network, wherein the ratio of the diameter of the polymer microspheres to the diameter of the nanofiber is over 30. The polymer microspheres melt to form a dielectric coating of the electrode so as to prevent fire or thermal runaway at a temperature approximately from 100 to 200° C.
