Abstract: The present application provides a lithium ion battery including a thermal sensitive layer comprising polymer particles. The thermal sensitive layer may be disposed between the electrodes and the separator. When the lithium ion battery is under thermal runaway condition and the internal temperature rises to a critical temperature, the polymer particles undergo a thermal transition process (melting) to form an insulating barrier on the electrodes, which blocks lithium ion transfer between the electrodes and shuts down the internal current of the battery.

Abstract: A pressure distribution mapping system includes a flexible M×N textile-based pressure sensor array. with first and second electrode textile layers and a piezoresistive fabric layer with a sheet resistance of at least 60 k-ohm/square positioned between the first and second electrode textile layers. Individual pressure sensors are formed by an intersection between a row electrically-conductive path and a column electrically-conductive path along with the portion of the piezoresistive layer positioned at the intersection. A measurement system measures the resistance of each pressure sensor of the pressure sensor array. The measurement system includes a reading module with first op-amps connected to each row and second op-amps connected to each column. Plural switches switch between pressure sensor-enabled and pressure sensor-disabled positions to minimize a bus line crosstalk effect during pressure sensor reading A processor scans each pressure sensor and generates a pressure distribution profile based on a measured resistance of each pressure sensor.

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.
