Abstract
A low-cost direct melt foaming approach was used to develop a new Pb alloy-based composite foams containing hybrid of gas pores and closed cell porosity in the form of hollow ceramic particles to be alternative to the traditional Pb grids in Lead acid battery (LAB). The novel Pb alloy-based composite foams were used as plates in manufacturing of lightweight LAB. The LAB was evaluated in terms of weight saved and electrochemical performance, including cyclic voltammetry, galvanostatic polarization and specific discharge capacity. The cyclic voltammetry results of the composite foams revealed that the composite foam required a higher voltage for oxidation, indicating that Pb oxidation occurred at a slower rate in the composite foams. Galvanostatic measurements showed that the composite foam took a longer duration in the oxidation of Pb into PbSO4 , implying that the battery developed in the current work would have a longer lifespan than a conventional LAB. The specific electrical discharge capacity of the LAB made of composite foams was higher than that of traditional LAB. The density of the composite foam plate was much lower than those of the conventional Pb alloys, indicating that the weights of the composite foam plates were lower than those of the conventional lead alloys. These findings suggested that the LAB with plates made of composite foams developed in the present work can be a feasible alternative to traditional Pb grids used in LAB.
