Abstract: A method of making a calendered electrode for a battery cell comprises introducing a coated electrode having a first surface extending thereover. The coated electrode has a predetermined density of active materials for ion transport. The method further comprises selectively modifying the coated electrode by patterning the first surface to define a patterned electrode having a first portion and a second portion. After the step of selectively modifying, the method further comprises compressing the patterned electrode by calendering the first surface to provide the first portion having a first density of active materials and the second portion having a second density of active materials. The second density is greater than the first density to define the calendered electrode having a spatial variation of active material density.

Abstract: A method of analyzing the quality of a battery cell includes performing a high-throughput quality check on the battery cell with a quality control system, assessing a quality score to the battery cell, with quality score identifying the battery cell as low-quality or high-quality, and performing a comprehensive quality check on the battery cell if identified as low-quality. The method further includes assessing an enhanced quality score to the battery cell superseding the quality score of the quality control system identifying the battery cell as confirmed low-quality or confirmed high-quality and providing revised production instructions for manufacturing successive battery cells if confirmed low-quality.

Abstract: Systems and methods are provided for fixturing hairpins for joining by welding. A fixture system includes an outer structural ring fixed relative to an inner structural ring and mates with the component around its hairpin type conductor ends. Dielectric rings are disposed between conductor pairs. Clamp rings are disposed on opposite sides of the dielectric rings. One clamp ring and one dielectric ring define an opening receiving one conductor pair. Another clamp ring and another dielectric ring define another receiving another conductor pair. The clamp rings are movable toward one another to align and crowd the conductor pairs between the clamp rings and the dielectric rings prior to welding.

Abstract: A transmission includes a housing, and a transmission input member. A torque converter includes a pump and a turbine. The turbine of the torque converter is connected to the transmission input member. A lock-up clutch selectively connects the pump and the turbine. A cover is connected to and rotatable with the pump. The cover at least partially defines an interior of the torque converter. A torque converter input member passes through the cover. A one way clutch interconnects the torque converter input member and the cover. An engine brake friction clutch is disposed within the interior of the torque converter. The engine brake friction clutch selectively interconnects the torque converter input member and the cover in torque communication to transfer a braking torque therebetween.

Abstract: A system for evaluating a battery cell includes an imaging device configured to take an image of at least part of the battery cell, and a processor. The processor is configured to perform: determining a region of interest in the acquired image, reducing a sharpness of the acquired image to generate a reference image, comparing the acquired image and the reference image, and identifying a discontinuity of the battery cell based on a difference between the acquired image and the reference image.

Abstract: Presented are clutch-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes a notch plate, which has multiple notches and attaches to a torque converter, and a pocket plate, which has multiple pockets and attaches to an engine's crankshaft. A pawl is movably mounted within each notch; these pawls selectively engage the notches with the pockets. A notch plate insert is nested within each notch, supporting thereon one of the pawls. A selector plate interposed between the pocket and notch plates moves from a first position, to shift the pawls out of engagement with the pockets, and a second position, to move the notch plate inserts within the notches and allow the pawls to engage the notches with the pockets to thereby lock the notch plate to the pocket plate to rotate in unison with each other.

Abstract: Presented are wedge-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes an outer race that attaches to a torque converter's pump cover. The outer race's inner diameter (ID) surface has circumferentially spaced grooves. An inner race is concentrically aligned within the outer race and attaches to an engine's output shaft. The inner race's outer diameter (OD) surface has circumferentially spaced pockets. A wedge plate interposed between the inner and outer races has multiple circumferentially spaced ramps. Each ramp slidably mounts within one groove and one pocket. The wedge plate moves between an engaged position, whereat the ramps wedge between the ID and OD surfaces to thereby transfer torque between the inner and outer races, and a disengaged position, whereat the ramps unwedge to thereby free the inner race to rotate with respect to the outer race.

Abstract: A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. A multi-component damping mechanism is disposed between the input member and the output member which includes a first spring element cooperating with a second spring element to couple the input member to the output member. The first spring element defines a greater stiffness and shorter deflection relative to the second spring element.

Abstract: A system for transporting a non-Newtonian material. The system includes a storage container configured to store the non-Newtonian material and a dispensing system configured to dispense the non-Newtonian material. A conduit connects the storage container to the dispensing system. The conduit is configured to transport the non-Newtonian material from the storage container to the dispensing system. A pump is configured to pump the non-Newtonian material out of the storage container and through the conduit to the dispensing system. A hanger is configured to support the conduit from a support structure. An acoustic wave generator is along the conduit configured to impart acoustical shear agitation to the non-Newtonian material to reduce viscosity of the non-Newtonian material.
