Abstract: The invention describes the unique finding that UV-curable flexo (and single pass inkjet) ink compositions can be more effectively cured by curing the pigmented ink compositions through two or more exposures to UV rather than a single exposure, where the total UV dose supplied by the multi-exposure approach is the same or less than the dose supplied by the single exposure.

Abstract: A method for modifying an electrode comprising an alkali metal is disclosed, the method comprising casting a salt solution comprising at least one salt comprising an alkaline ion and a solvent on the electrode; casting a fluoropolymer solution comprising at least one fluoropolymer and a solvent on the electrode; and drying the electrode. Also disclosed is an electrode comprising an alkali metal at least partly covered by a solid electrolyte interphase, said solid electrolyte interphase having atomic ratios of carbon, fluorine and sulfur atoms of 1 C:0.15 to 0.80 F:0.02 to 0.30 S.
