    摘要： A method of applying a separator ink onto a dried electrode of a lithium ion battery. The method includes preparing a separator ink suspension, applying the separator ink suspension onto the dried electrode, and drying the applied separator ink suspension. The separator ink suspension includes a binder comprising 20 wt % to 50 wt % of a total weight of the separator ink suspension, the binder being selected from the group consisting of polyvinylidene fluoride (PVDF), polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP), polytetrafluoroethylene (PTFE), poly(ethylene oxide) (PEO), Poly(methyl methacrylate (PMMA), polyacrylonitrile (PAN), carboxymethyl cellulose (CMC), styrene-butadiene rubber (SBR), and combinations thereof, a solvent selected from the group consisting of N-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), acetone, dimethylacetamide (DMAc), dimethyl sulfoxide (DMSO), trimethyl urea, triethyl phosphate, and combinations thereof, a non-solvent selected from the group consisting of glycerol, water, ethanol, methanol, ethylene glycol, diethylene glycol, triethylene glycol, hexane, heptane, and combinations thereof, and a ceramic filler comprising 50 wt % to 80 wt % of the total weight of the composite electrolyte the ceramic filler being selected from the group consisting of Al2O3, SiO2, TiO2, MgO, Li2O, LiAlO2, BaTiO3, lithium aluminum germanium phosphate (LAGP), lithium aluminum titanium phosphate (LATP), lithium lanthanum titanate (LLTO), and combinations thereof.

    摘要： A passive filter for an aerosol printing system. The passive filter includes a housing having a fluid inlet port at a first end and a fluid outlet port at a second end, the fluid inlet and outlet ports being coaxial. A chamber is disposed within the housing and has a ceiling, a base, at least one wall between the ceiling and the base, a chamber entrance in the ceiling, and a chamber exit. The chamber entrance and exit being coaxial to the fluid inlet and outlet ports. The chamber exit is disposed within chamber between the chamber entrance and the base and defining a circumferential trough about the chamber exit.

    摘要： A method for aerosol-jet printing a layered perovskite structure by applying a PEDOT:PSS layer to a substrate; applying a layer of lead iodide (PbI2) to the PEDOT:PSS layer; and applying an aerosol mist of methylammonium iodide (CH3NH3I) atop the PbI2 layer with an aerosol-jet nozzle to form a CH3NH3PbI3 perovskite film layer. The substrate may be an ITO glass substrate, and the PEDOT:PSS layer may be applied by a process selected from spin-coating, inkjet-printing, slot-die-coating, aerosol-jet printing, physical vapor deposition, chemical vapor deposition, and electrochemical deposition. The PbI2 layer may be applied by a process selected from spin-coating, aerosol-jet printing, inkjet-printing, slot-die-coating, physical vapor deposition, chemical vapor deposition, and electrochemical deposition, and the PbI2 for application to the PEDOT:PSS layer may be in a solution of DMF, DMSO, γ-butyrolactone, or a combination thereof.
