Abstract: Fast-charging lithium ion cells are provided, which have electrolytes that do not react with the cell anodes, but instead form a solid-electrolyte interphase (SEI) on the cathodes. Advantageously, such electrolytes improve the performance of the fast-charging cells, and enhance their lifetime and safety. Various electrolyte solutions and lithium ions are proposed to limit electrolyte interactions to the cathodes, or possibly even minimize or prevent these reactions by coating the cathodes. Redox couples may be used to prevent SEI formation on the anode, while promoting SEI formation on the cathode.

Abstract: This invention is directed to photoluminescent compounds based on rhodamine dyes with red-shifted absorption and emission maxima and uses thereof for photoluminescence based devices.

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.
