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: The present invention discloses systems and methods for adaptive fast-charging for mobile devices and devices having sporadic power-source connection. Methods include the steps of: firstly determining whether a supercapacitor of a device is charged; upon detecting the supercapacitor is charged, secondly determining whether a battery of the device is charged; and upon detecting the battery is not charged, firstly charging the battery from the supercapacitor. Preferably, the step of firstly determining includes whether the supercapacitor is partially charged, and the step of secondly determining includes whether the battery is partially charged. Preferably, the step of firstly charging is adaptively regulated to perform a task selected from the group consisting of: preserving a lifetime of the battery by controlling a current to the battery, and discharging the supercapacitor in order to charge the battery. Preferably, the discharging enables the supercapacitor to be subsequently recharged.

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: 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.
