Abstract
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.
