Abstract
The present application belongs to the field of new energy technology. The present application provides a preparation method for copper-aluminum composite pole plate, which comprises: heating the aluminum ingot to 700-800° C. for smelting, and allowing the aluminum ingot liquid at 700-800° C. to stand still for 0-30 minutes to obtain an aluminum solution, roughening and cleaning the copper strip to complete the surface pretreatment of the copper strip, continuously casting aluminum strips on aluminum solution after being left to stand, and forming pole aluminum bosses through forming rollers, increasing the copper-aluminum bonding strength, and side discharging aluminum waste, molding at room temperature for the forming of fine features of the boss and the shaping of large bosses during rolling, cutting the pole and determining whether the battery pole product meets the standard, thereby improving the preparation process and equipment for the copper-aluminum composite material for the pole.
