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: Core-shell particles, composite anode material, anodes made therefrom, lithium ion cells and methods are provided, which enable production of fast charging lithium ion batteries. The composite anode material has core-shell particles which are configured to receive and release lithium ions at their cores and to have shells that are configured to allow for core expansion upon lithiation. The cores of the core-shell particles are connected to the respective shells by conductive material such as carbon fibers, which may form a network throughout the anode material and possibly interconnect cores of many core-shell particles to enhance the electrical conductivity of the anode. Ionic conductive material and possibly mechanical elements may be incorporated in the core-shell particles to enhance ionic conductivity and mechanical robustness toward expansion and contraction of the cores during lithiation and de-lithiation.

Abstract: Methods, stacks and electrochemical cells are provided, in which the cell separator is surface-treated prior to attachment to the electrode(s) to form binding sites on the cell separator and enhance binding thereof to the electrode(s), e.g., electrostatically. The cell separator(s) may be attached to the electrode(s) by cold press lamination, wherein the created binding sites are configured to stabilize the cold press lamination electrostatically—forming flexible and durable electrode stacks. Electrode slurry may be deposited on a sacrificial film and then attached to current collector films, avoiding unwanted interactions between materials and in particular solvents involved in the respective slurries. Dried electrode slurry layers may be pressed or calendared against each other to yield thinner, smother and more controllably porous electrodes, as well as higher throughput. The produced stacks may be used in electrochemical cells and in any other type of energy storage device.

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.
