Abstract: Lithium ion batteries and electrolytes therefor are provided, which include electrolyte additives having dithioester functional group(s) that stabilize the SEI (solid-electrolyte interface) at the surfaces of the anode material particles, and/or stabilize the CEI (cathode electrolyte interface) at the surfaces of the cathode material particles, and/or act as oxygen scavengers to prevent cell degradation. The electrolyte additives having dithioester functional group(s) may function as polymerization controlling and/or chain transfer agents that regulate the level of polymerization of other electrolyte components, such as VC (vinyl carbonate) and improve the formation and operation of the batteries. The lithium ion batteries may have metalloid-based anodes—including mostly Si, Ge and/or Sn as anode active material particles.

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.
