    Abstract: A method of making the sulfide-impregnated solid-state battery is provided. The method comprises providing a cell core that is constructed by cell unit. The cell core is partially sealed into the packaging such as the Al laminated film and metal can. The method further comprises introducing a sulfide solid-state electrolyte (S-SSE) precursor solution in the cell core, the S-SSE precursor solution comprises a sulfide solid electrolyte and a solvent. The method further comprises evaporating the solvent from the cell core to dry the cell core to solidify the sulfide-based solid-state electrolyte within the cell core and pressurizing the cell core to densify the solid sulfide-base electrolyte within the cell core. The cell core is then fully sealed.

    Abstract: A wear-resistant component includes a substrate formed from a metal, defining a bore, and having a bore surface. The substrate includes a first region having a first microstructure adjacent the bore surface and a first average particle size. The substrate also includes a second region having a second microstructure adjacent the first microstructure and a second average particle size. The first average particle size is larger than the second average particle size. A system and a method of forming the wear-resistant coating are also described.

    Abstract: A capacitor-assisted, solid-state lithium-ion battery is formed by replacing at least one of the electrodes of the battery with a capacitor electrode of suitable particulate composition for the replaced battery particulate anode or cathode material. The solid-state electrodes typically contain solid-state electrode material and are separated with solid-state electrode material. In another embodiment the capacitor anode or cathode particles may be mixed with lithium-ion battery anode or cathode particles respectively. Preferably, the battery comprises at least two positively-charged electrodes and two negatively-charged electrodes, and the location and compositions of the capacitor material electrode(s) may be selected to provide a desired combination of energy and power.

    Abstract: A wastegate actuator assembly includes a regulating rod, an arm, and a shaft. The regulating rod includes a proximate end region and a distal end region wherein the proximate end region of the regulating rod may be connected to an actuator. The arm includes a first end region and a second end region. The first end region is pivotally coupled to the distal end region of the regulating rod via a crank pin, a first cup spring, and a second cup spring wherein the first and second cup springs retain a solid lubricant substantially around the crank pin. The regulating rod may move in a linear fashion causing the arm and the shaft to rotate so as to move a wastegate cover connected to the shaft from a closed wastegate duct position (toward the wastegate duct) to an open wastegate duct position (away from the wastegate duct).

    Abstract: Methods for profiling a bore of an engine block are provided. Methods can comprise profiling the bore surface with a qualitative optical device (QlOD) to determine a qualitative surface characteristic map of the bore surface, wherein the QlOD comprises a light source configured to emit light toward the bore surface at an emitting angle, and a sensor array configured to sense scattered light reflected from the bore surface, and comparing the qualitative surface characteristic map to a calibration value to determine the suitability of the bore surface for thermal spray deposition. Methods can further include profiling the bore surface with a quantitative optical device (QnOD) to determine a quantitative surface characteristic, and determining a quantitative-qualitative correlation. Methods can further include profiling additional sample areas of the bore surface with the QlOD to determine a qualitative surface characteristic map of the bore surface and applying the correlation to the map.
