Abstract: A method for manufacturing a current collector for an electrode of a battery cell includes providing a wire mesh current collector including wires that have a diameter and form mesh junctions; and rolling the wire mesh current collector using a first roller and a second roller, wherein the first roller and the second roller are spaced by a predetermined gap. The predetermined gap is less than 2 times the diameter of the wires of the wire mesh current collector.

Abstract: A method for manufacturing a current collector for an electrode of a battery cell includes forming the current collector using a metal 3D printing process; defining L layers of the current collector, where L is an integer greater than zero during the 3D printing of the current collector; and defining a lattice structure in at least one of the L layers of the current collector during the 3D printing of the current collector.

Abstract: A shear panel construction includes a patterned upper sheet metal panel including a planar section and having a plurality of upwardly protruding portions defining first strengthening crossbar sections extending upward from the planar section, the planar section of the patterned upper sheet metal panel extends to an edge of the patterned upper sheet metal panel. A patterned lower sheet metal panel is secured to a bottom surface of the patterned upper sheet metal panel, the patterned lower sheet metal panel having a plurality of protruding portions defining second strengthening crossbar sections.

Abstract: A method for fabricating an anode electrode includes providing a stainless steel current collector, forming a metal oxide layer on the stainless steel current collector, and pouring molten lithium over the metal oxide layer of the stainless steel current collector to create a lithium metal layer on the metal oxide layer.

Abstract: A method for manufacturing electrodes for a battery cell includes providing a first free-standing electrode; providing a current collector including holes; providing a second free-standing electrode; and laminating the current collector between the first free-standing electrode and the second free-standing electrode using at least one of heat and pressure and without using a solvent.

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 gradient steel includes a first layer, a second layer near a first surface of the first layer, and a third layer near a second surface of the first layer. The first layer includes a first ferrite phase volume. The second and third layers include a second ferrite phase volume greater than the first ferrite phase volume. The gradient steel may also include a fourth layer near the second layer and a fifth layer near the third layer. The fourth and fifth layers may each include a third ferrite phase volume greater than the second ferrite phase volume. The gradient steel may also include a sixth layer near the fourth layer and a seventh layer near the fifth layer. The sixth and seventh layers may each include a fourth ferrite phase volume greater than the third ferrite phase volume.
