Abstract: A method for forming a layered anode material includes contacting a precursor material and a first electrolyte. The precursor material is a layered ionic compound represented by MX2, where M is one of calcium and magnesium and X is one of silicon, germanium, and boron. The method further includes applying a first bias and/or current as the precursor material contacts the first electrolyte to remove cations from the precursor material to create a two-dimensional structure that defines the layered anode material. In certain variations, the method further includes contacting the two-dimensional structure and a second electrolyte and applying a second bias and/or current as the two-dimensional structure contacts the second electrolyte so as to cause lithium ions to move into interlayer spaces or voids created in the two-dimensional structure by the removal of the cations thereby forming the layered anode material.

Abstract: The present disclosure describes a method of manufacturing a vehicle body structure component. The method includes extruding a tube to include at least one reinforced region extending along a length of the tube. The tube has a first thickness in the at least one reinforced region and a second thickness in other regions of the tube. The first thickness is greater than the second thickness. The method further includes cutting a blank from the tube such that the blank includes at least a portion of the at least one reinforced region and forming the blank into a desired shape of the component.

Abstract: A sheet metal assembly includes a drawn metal sheet constructed of a metal material. The drawn metal sheet defines a surface and includes one or more stiffening features disposed along the drawn metal sheet. The one or more stiffening features represents a raised area disposed along the surface of the drawn metal sheet. Each of the one or more stiffening features include a predefined draw depth ranging from about twenty millimeters to about eighty millimeters.

Abstract: A method for forming a prelithiated, layered anode material includes contacting an ionic compound and a lithium precursor in an environment having a temperature ranging from about 200° C. to about 900° C. The ionic compound is a three-dimensional layered material represented by MX2, where M is one of calcium (Ca) and magnesium (Mg) and X is one of silicon (Si), germanium (Ge), and boron (B). The lithium precursor is selected from the group consisting of: LiH, LiC, LiOH, LiCl, and combinations thereof. The contacting of the ionic compound and the lithium precursor in the environment causes removal of cations from the ionic compound to create openings in interlayer spaces or voids in the three-dimensional layered material thereby defining a two-dimensional layered material and also causes introduction of lithium ions from the lithium precursor into the interlayer spaces or voids to form the prelithiated, layered anode material.

Abstract: A structural assembly includes a frame and a plurality of panels. The frame includes a wall that at least partially defines an interior region. The plurality of panels is disposed at least partially in the interior region and is coupled to the frame. The plurality of panels includes a first panel and a second panel. The first panel includes a first surface and a second surface opposite the first surface. The first surface defines a first plurality of depressions and the second surface defines a first plurality of protrusions complementary to the first plurality of depressions. The second panel includes a third surface and a fourth surface opposite the third surface. The third surface defines a second plurality of depressions. The fourth surface defines a second plurality of protrusions complementary to the first plurality of depressions. The first panel is coupled to the second panel.

Abstract: A steel workpiece includes an alloy substrate comprising iron, about 1.4 to about 2.0 weight percent aluminum, and about 0 to about 1.0 weight percent silicon. The steel workpiece further includes a coating comprising zinc. A method of spot welding a workpiece stack-up that includes a pair of the steel workpieces includes providing the stack-up, contacting first and second electrodes to the steel workpieces, passing an electrical current through the stack-up, forming a weld nugget from molten mixing of the alloy substrates of the pair of steel workpieces, forming a boundary layer between the coating and the alloy substrate from dispersion of the coating into the alloy substrate and reaction of the zinc with the aluminum and the silicon to prevent molten mixing of the coating within the alloy substrate, and ceasing passage of the electrical current.
