Abstract: Methods, stacks and electrochemical cells are provided, which improve production processes and yield flexible and durable electrode stacks. Methods comprise depositing an electrode slurry on a sacrificial film to form an electrode thereupon, wherein the electrode slurry comprises a first solvent, attaching (e.g., laminating) a current collector film, which is produced at least partly using a second solvent, onto the formed electrode, to yield a stack, wherein a binding strength of the electrode to the current collector film is higher than a binding strength of the electrode to the sacrificial film, and delaminating the sacrificial film from the electrode while maintaining the attachment of the electrode to the current collector film. Additional layers such as a cell separator and an additional electrode may be further attached using similar steps.

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.

Abstract: Cathodes for a fast charging lithium ion battery, processes for manufacturing thereof and corresponding batteries are provided. Cathode formulations comprise cathode material having an olivine-based structure, binder material, and monomer material selected to polymerize into a conductive polymer upon partial delithiation of the cathode material during at least a first charging cycle of a cell having a cathode made of the cathode formulation. When the cathode is used in a battery, polymerization is induced in-situ (in-cell) during first charging cycle(s) of the battery to provide a polymer matrix which is evenly dispersed throughout the cathode.

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.
