    摘要: Additive manufacturing processes, such as fused filament fabrication, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of a printed object. Conductive traces and similar features may be introduced in conjunction with fused filament fabrication processes by incorporating a metal precursor in a polymer filament having a filament body comprising a thermoplastic polymer, and forming a printed object from the polymer filament through layer-by-layer deposition, in which the metal precursor remains substantially unconverted to metal while forming the printed object. Suitable polymer filaments compatible with fused filament fabrication may comprise a thermoplastic polymer defining a filament body, and a metal precursor contacting the filament body, in which the metal precursor is activatable to form metal islands upon laser irradiation.

    摘要: An electrochemical device is disclosed, which may include an anode, a cathode, and a molded electrolyte composition disposed between the anode and the cathode. Implementations of the electrochemical device may include where the cathode and/or the anode are disposed in a stacked geometry. The electrolyte composition may include a gel polymer electrolyte, which can include a hydrogel of a copolymer and a salt dispersed in the hydrogel of a copolymer. The electrolyte composition may alternatively include a crosslinker or a photoinitiator. A method of producing an electrolyte layer of an electrochemical device is also disclosed, including preparing a substrate having an electrode for an electrochemical device, preparing a gasket to form a cavity on the substrate for the electrolyte layer, and depositing an electrolyte composition onto the substrate
