Patent number: 11276850Abstract: 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.Type: GrantFiled: January 2, 2020Date of Patent: March 15, 2022Assignee: STOREDOT LTD.Inventors: Eran Sella, Leora Shapiro, Rony Schwarz, Moria Koren, Maxim Kagan

Publication number: 20210191198Abstract: LCDs (liquid crystal displays) with improved efficiency and performance, as well as corresponding methods are disclosed. Color conversion films and elements with rhodamine-based fluorescent compounds and/or assistant dyes are used to modify the spectrum of the illumination provided by the backlight unit in either or both the backlight unit itself and the LCD panel, in various configurations. Color conversion may be performed above the LC module, possibly by a patterned layer incorporating the color filters, and/or within the backlight unit within a fluorescence-intensifying section in which radiation is recycled to enhance color conversion. Film configuration, positions and optionally supportive structures are provided, to extend the lifetime of the fluorescent compounds. Collimation of backlight illumination may further enhance the optical performance of disclosed LCDs.Type: ApplicationFiled: December 18, 2019Publication date: June 24, 2021Applicant: MolecuLED Ltd.Inventors: Sanaa MUSA, Rony SCHWARZ, Eran SELLA, Daniel SZWARCMAN, Maxim LIBERMAN, Evgenia Liel (Jeny) KUKS, Ziv SOBOL, Daniel ARONOV, Mor Shmuel ARMON, Elad Cohen

Patent number: 10519314Abstract: 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.Type: GrantFiled: November 16, 2016Date of Patent: December 31, 2019Assignee: StoreDot Ltd.Inventors: Daniel Szwarcman, Elad Cohen, Mor Shmuel Armon, Evgenia Leil (Jeny) Kuks, Rony Schwarz, Elena Eisurovich, Daniel Aronov, Eran Sella
