Influence of Process Parameters on Paste Morphology in Lead-Acid Battery Cured Plates

This study aim is to understand the effects of paste preparation process parameters Acid/Oxide ratio, paste peak temperature and curing temperature on establishing the crystal morphology of paste and to optimize the conditions to favor homogeneity and good crystal morphology. Full factorial DoE technique with three factors in three levels was used to design the experiments. The paste prepared as per experiment design was analyzed for surface area using gas adsorption method, for crystal size using scanning electron microscope and analyzed by XRD to confirm the relative proportions of crystals. It was found that paste peak temperature and curing temperature exhibited significant influence in controlling the surface area and crystal growth. While Acid/Oxide ratio having influence in surface area and a effect on crystal distribution.
