    Abstract: Color conversion films for an 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. The color conversion films may comprise at least one of: polydimethylsiloxane hydroxy terminated, dendritic polyol or polyvinylpyrrolidone.

    Abstract: Methods of preparing Si-based anode slurries and anode made thereof are provided. Methods comprise coating silicon particles within a size range of 300-700 nm by silver and/or tin particles within a size range of 20-500 nm, mixing the coated silicon particles with conductive additives and binders in a solvent to form anode slurry, and preparing an anode from the anode slurry. Alternatively or complementarily, silicon particles may be milled in an organic solvent, and, in the same organic solvent, coating agent(s), conductive additive(s) and binder(s) may be added to the milled silicon particles—to form the Si-based anode slurry. Alternatively or complementarily, milled silicon particles may be mixed, in a first organic solvent, with coating agent(s), conductive additive(s) and binder(s)—to form the Si-based anode slurry. Disclosed methods simplify the anode production process and provide equivalent or superior anodes.

    Abstract: Electrolytes, anode material particles and methods are provided for improving performance and enhancing the safety of lithium ion batteries. Electrolytes may comprise ionic liquid(s) as additives which protect the anode material particles and possibly bind thereto; and/or may comprise a large portion of fluoroethylene carbonate (FEC) and/or vinylene carbonate (VC) as the cyclic carbonate component, and possibly ethyl acetate (EA) and/or ethyl methyl carbonate (EMC) as the linear component; and/or may comprise composite electrolytes having solid electrolyte particles coated by flexible ionic conductive material. Ionic liquid may be used to pre-lithiate in situ the anode material particles. Disclosed electrolytes improve lithium ion conductivity, prevent electrolyte decomposition and/or prevents lithium metallization on the surface of the anode.

    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.
