description 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 such that the current collector substrate is sandwiched between the portions to form an electrode blank, and sectioning the electrode blank into zinc negative electrodes. Un método para fabricar electrodos negativos de zinc incluye mezclar un polvo que incluye zinc con politetrafluoroetileno para formar una mezcla homogénea, inyectar un lubricante en la mezcla homogénea para formar una masa, amasar la masa para formar una masa fibrilada, y extruir la masa fibrilada a través de un troquel para formar una cinta. El método también incluye calandrar la cinta a un espesor objetivo para formar una placa, secar la placa para formar una hoja de material activo, laminar porciones de la hoja de material activo a un sustrato de colector de corriente de tal manera que el sustrato de colector de corriente se intercale entre las porciones para formar un blanco de electrodo, y cortar el blanco del electrodo en electrodos negativos de zinc.
