摘要： A method for manufacturing zinc negative electrodes includes mixing a powder including zinc with polytetrafluoroethylene to form a homogenous blend, injecting a lubricant into the homogenous blend to form a dough, kneading the dough to form a fibrillated dough, and extruding the fibrillated dough through a die to form a ribbon. The method also includes calendering the ribbon to a target thickness to form a plaque, drying the plaque to form an active material sheet, laminating portions of the active material sheet to a current collector substrate to form an electrode blank, and sectioning the electrode blank into zinc negative electrodes.

摘要： An electrode includes a current collector, a metal shell in direct contact with and encapsulating the current collector, green dendritic columnar growths extending out of the metal shell and having protrusions thereon, and active material in contact with the metal shell and having embedded therein the green dendritic columnar growths. The protrusions penetrate the active material to form a mechanical retainer that prevents delamination of the active material from the metal shell and define localized regions of increased current density during operation of the electrode that promote deposition of the active material first on the protrusions and then on areas of the green dendritic columnar growths adjacent to the protrusions such that the active material electrochemically adheres to the green dendritic columnar growths and the protrusions enlarge during repeated charge and discharge cycling of the electrode.

摘要： A method for manufacturing electrodes includes, by an extruder that receives powder, mixing the powder to form a homogenous blend, injecting a lubricant into the homogenous blend to form a dough, and kneading the dough to form a fibrillated dough. The method further includes, by calender rollers, calendering chunks of the fibrillated dough to a target thickness to form a continuous plaque, by a laminating machine, laminating the plaque to opposite sides of a metal substrate to form a continuous electrode preform, by a dryer, drying the continuous electrode preform to form a dry continuous electrode preform, and by a cutting machine, sectioning the dry continuous electrode preform into electrodes.

摘要： An electrode includes a current collector having metallic struts formed by freeze tape casting along a cast direction, and an electrochemically active material occupying portions of the void spaces. The struts define a percolated conductive network and void spaces through the percolated conductive network. The struts are directionally aligned and the void spaces are directionally ordered perpendicular to the cast direction.

摘要： A pouch cell includes an electrode assembly and a body forming a gas headspace within the pouch. Tabs of the electrode assembly may extend through or around the body and out of the pouch. Gas from the electrode assembly may collect in the gas headspace. The body may accommodate a vent mechanism that also extends out of the pouch.

摘要： An aqueous battery system includes an electrode assembly, a recombination device, and a controller. The recombination device has a catalyst that combines hydrogen and oxygen produced by the electrode assembly to form water and generate heat via exothermic reaction. The controller, responsive to a detected temperature or change in temperature associated with the recombination device due to the heat, changes power supplied to the electrode assembly.
