Emissions of lead particulates, sulfur oxides and their potential environmental risks are received great attention in traditional pyrometallurgical process for recycling spent lead-acid battery. In recent years, envir. ••The latest progress on the clean recovery processes of spent LAB. Lead-acid battery (LAB) has widespread applications in uninterrupted power supplies, electric vehicles, energy storage, traction and starting, lighting and ignition (SLI) batteries [[1. 2.1. Desulfurization pretreatment of the spent lead pasteLead sulfate accounts for about 60 wt% in the spent lead paste. Due to its stability, it does not react wi. 3.1. Metallic lead and PbO for new LAB manufacturingMost products of electrowinning process are metallic lead, which is deposited on the cathode (Table 3. 4.1. The impurity removalThe current trend is intensification of research in the hydrometallurgical methods. Many new options have been proposed and studied by many.
