The replacement of lead grids with acrylonitrile butadiene styrene (ABS) polymer grids in the negative
electrode of lead-acid batteries was studied experimentally, while the positive electrode remained unchanged. A polymer
grid was activated by nickel plating using a chemical solution, and then coated with chrome and copper conductive
plating. The polymer grid was coated with a layer of lead. Using a lead-coated polymer grid, a 30-amp 12-volt
battery was produced and tested, and the results were compared with a 30-hour production line lead-acid battery. The
results show that the polymer grid has a strong ability to generate an appropriate voltage in the charge and discharge
cycle and create a stable capacity. The results also show the polymer grid weight has decreased significantly (about
50%) compared to the conventional lead grid. In this work, the adhesion of a negative paste to the surface of the polymer
grid covered with the lead-exposed expand grid was studied, and the results show that the polymer grid can
adhere to the negative dough perfectly.
