Abstract: The process and principle to refine and alloy the secondary lead are proposed. Low-antimony alloy of lead-acid storage battery can be made from treated secondary lead. The high-antimony alloy, regular low-antimony alloy and secondary lead Low-antimony alloy have been compared in different experiments. Because some elements such as antimony, copper and bismuth are fully utilized in Low-antimony alloy based on secondary lead. This alloy has a low cost and good properties of casting, corrosion resistance, tensile strength and electricity.
