Abstract: A sulfide-based composite electrolyte for use in solid-state batteries and methods for making same. In some embodiments, the sulfide-based composite electrolyte comprises the combination of an inorganic sulfide Li argyrodite (Li7PS6) with a polyvinylidenefluoride-co-hexafluoropropylene (PVDF-HFP) polymer.

Abstract: Systems and methods for additive manufacturing. In some examples, a system includes a frame defining an interior volume and an overhead robotic arm suspended from a gantry on a ceiling of the frame. The system includes manufacturing subsystems located within the interior volume of the frame. The system includes a control system configured for controlling the overhead robotic arm for parts movement among additive manufacturing processes using the manufacturing subsystems. The manufacturing subsystems can include one or more of: a microassembly station, an aerosol jetting print station, an intense pulsed light (IPL) photonic sintering station, a fiber weaving station, and a 3D printing station.

Abstract: Embodiments of the invention employ frequency selective surfaces that resonate at defined frequencies depending on geometry. Tag-based embodiments allow the ability to have passive, battery-free, systems that can be used for applications including but not limited to inventory tracking, locating, and indoor radar (e.g. determining whether something labeled with a tag is in range of a particular wireless network signal). The shape of the resonator, among other available factors, influences the interference frequency. Embodiments may include metal based tags on a non-conductive material that will be used to disturb, for example, frequencies from 3 KHz to 300 GHz. These disturbances at specific resonant frequencies are useable to, for example, locate the tags/labels using WiFi Mapping, sending a WiFi signal and getting unique feedback on a router.

Abstract: A paste (32) for use in metallization of a solar cell (12) includes an organic vehicle (44) and a mixture of copper-containing particles (46), metal-oxide-containing nanoparticles (50), and secondary oxide particles (52) different from the metal-oxide-containing nanoparticles (50). The secondary oxide particles (52) include particles (42) of a metal oxide and a metal of the metal oxide capable of reducing at least some of the metal-oxide-containing nanoparticles (50) to metal when heated. The organic vehicle (44) is capable of reducing the metal oxide of the secondary oxide particles (52) upon decomposition of the organic vehicle (44). A paste (32) includes a mixture of particles (42) including metallic copper particles (46), nanoparticles (50), and metal oxide particles (52) in the organic vehicle (44). The nanoparticles (50) include at least one oxide of nickel, copper, cobalt, manganese, and lead.

Abstract: Methods for wet chemical synthesis of lithium argyrodites are provided, which in some embodiments include includes dissolving a stoichiometric mixture of precursors in a small quantity of solvent in an argon atmosphere, drying the mixture under vacuum or an inert gas atmosphere to evaporate the solvent, and then annealing to obtain a final lithium argyrodite product. Further embodiments comprise synthesizing the precursors, and excess halide doping to achieve higher ionic conductivity.

Abstract: A perovskite thin film and method of forming a perovskite thin film are provided. The perovskite thin film includes a substrate, a hole blocking/electron transport layer, and a sintered perovskite layer. The method of forming the perovskite solar cell includes depositing a perovskite layer onto a substrate and processing (for example, by sintering) the perovskite layer with intense pulsed light to initiate a radiative thermal response that is enabled by an alkyl halide additive.
