    Abstract: Color conversion films for a LCD (liquid crystal display) having RGB (red, green, blue) color filters, as well as such displays, formulations, precursors and methods are provided, which improve display performances with respect to color gamut, energy efficiency, materials and costs. The color conversion films absorb backlight illumination and convert the energy to green and/or red emission at high efficiency, specified wavelength ranges and narrow emission peaks. For example, rhodamine-based fluorescent compounds are used in matrices produced by sol gel processes and/or UV (ultraviolet) curing processes which are configured to stabilize the compounds and extend their lifetime—to provide the required emission specifications of the color conversion films. Film integration and display configurations further enhance the display performance with color conversion films utilizing various color conversion elements. Fluorescent emission may be enhanced by plasmon resonance of coupled nanoparticles.

    Abstract: Electrolytes, anodes, lithium ion cells and methods are provided for preventing lithium metallization in lithium ion batteries to enhance their safety. Electrolytes comprise up to 20% ionic liquid additives which form a mobile solid electrolyte interface during charging of the cell and prevent lithium metallization and electrolyte decomposition on the anode while maintaining the lithium ion mobility at a level which enables fast charging of the batteries. Anodes are typically metalloid-based, for example include silicon, germanium, tin and/or aluminum. A surface layer on the anode bonds, at least some of the ionic liquid additive to form an immobilized layer that provides further protection at the interface between the anode and the electrolyte, prevents metallization of lithium on the former and decomposition of the latter.

    Abstract: The present invention discloses integrated power-management units in energy-storage devices for fast-charging of rechargeable devices. Energy-storage devices include: an energy-storage component for providing power to a rechargeable device; and an integral power-management unit (PMU), integrally connected to the energy-storage component, for transforming a high-power input, having an input voltage and a low input RMS current, into a high-power output, having an output voltage and a high output RMS current, wherein the high-power input is equal to the high-power output, and wherein the high-power output is configured to charge the energy-storage component. Preferably, the PMU is configured to minimize resistive losses, wherein the resistive losses are designated as a mathematical product of the square of the high output RMS current (IRMS2) and an output circuit resistance between the integral PMU and the energy-storage component, and wherein the mathematical product is symbolically defined as IRMS2×R, associated with the high-power output.
