Abstract: A vehicle hood covering an underhood object includes an inner surface of the vehicle hood facing the underhood object and spaced from the underhood object, and an outer surface of the vehicle hood opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the vehicle hood. The local energy absorber is a multiply-connected structure. The local energy absorber includes a wall defining an interior surface having symmetry about a central plane normal to the inner surface of the vehicle hood. A plurality of apertures is defined in the wall symmetrically about the central plane to initiate buckling and fracture in the wall during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.

Abstract: A composite electrode for an electrochemical cell that cycles lithium ions may include a metal current collector having a three-dimensional porous structure defining an interconnected network of open pores and an electrode material disposed within the open pores of the current collector. An oxygen-containing reactive layer may be formed on surfaces of the current collector and an electrode precursor mixture may be deposited thereon and dried to form a solid electrode material having a continuous structure within the open pores of the current collector. The electroactive material particles and/or the electrically conductive agent may interact with the oxygen-containing reactive layer on the metal current collector to form an oxygen-containing adhesive layer along an interface between the current collector and the solid electrode material. The electroactive material particles and the electrically conductive agent may be chemically bonded to the current collector via hydrogen bonds within the oxygen-containing adhesive layer.

Abstract: A method for preparing an electroactive material for an electrochemical cell that cycles lithium ions includes applying a potential to a first assembly that includes a first electrode and an aqueous electrolyte. The aqueous electrolyte includes a lithium salt and as the potential is applied the lithium salt disassociates forming cations and anions. The first assembly is physically separated from a second assembly by a lithium ion-conducting separator. The second assembly includes a second electrode and a non-aqueous electrolyte. The electroactive material is formed as the cations move from the first assembly through the lithium ion-conducting separator towards the second electrode.

Abstract: An electrode assembly includes a current collector, a lithium metal foil, and an alloyed interface that chemically binds the current collector and the lithium metal foil. In certain variations, the alloyed interface includes an intermediate layer disposed between the current collector and the lithium metal foil, a portion of the current collector adjacent to the intermediate layer is alloyed with the indium, gallium, or alloy of indium and gallium defining the intermediate layer, and a portion of the lithium metal foil adjacent to the intermediate layer is alloyed with the indium, gallium, or alloy of indium and gallium defining the intermediate layer. In other variations, the alloyed interface includes a copper-lithium alloy.

Abstract: A brake rotor having a composite structure may include an annular body defining opposite friction surfaces of the brake rotor. The annular body may include a core made of an Al—Si alloy, a thermal barrier layer made of a thermally insulating material disposed on the core, and a wear-resistant layer made of an Fe—Al—Si—Zr alloy disposed on the core over the thermal barrier layer. The wear-resistant layer may define a first one of the opposite friction surfaces of the annular body.
