Abstract: A structural member for a battery cell may be provided in the form of an I-beam having a central support structure that extends through the middle of the battery cell. One or more electrode stacks may be provided within one or more cavities defined by the structural member. The structural member may provide mechanical, structural, and/or thermal benefits for the battery cell and/or one or more battery sub-assemblies, battery modules, and/or battery packs. A battery cell includes a contoured housing with curved lateral surfaces conforming to a shape of one or more wound electrode layers. When the wound electrode layers are inserted into the contoured housing, space between the electrode layers and the contoured housing is reduced, as compared to that of square or rectangular housings, leading to higher wetting rate and lower wetting times of the wound electrode layers, higher structural loading, wider tolerances, and/or flexible cooling strategies.

Abstract: Described herein are medical devices and medical implements with high lubricity to flesh (or biological fluid) and/or inhibited nucleation on its surface. The device has a surface comprising an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between said solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface.

Abstract: Aspects of the subject disclosure relate to various features of a battery subassembly, such as a battery module. The battery subassembly may be implemented in an electric vehicle or in a building. In one or more implementations, the battery subassembly may include a battery cell having a peripheral rim having a first width and forming a terminal for the battery cell; and at least one weld configured to couple the peripheral rim to a connector, in which the at least one weld has a second width that is larger than the first width.

Abstract: The invention is directed to an article with a liquid-impregnated surface, the surface having a matrix of features thereupon, spaced sufficiently close to stably contain a liquid therebetween or therewithin, and preferable also a thin film thereupon. The surface provides the article with advantageous non-wetting properties. Compared to previous non-wetting surfaces, which include a gas (e.g., air) entrained within surface textures, these liquid-impregnated surfaces are resistant to impalement and frost formation, and are therefore more robust.
