Conclusions A research investigation for recycling lead from lead paste in the spent lead acid battery under vacuum has been developed in this work.
There are four main components in spent lead acid battery: polymeric containers, lead alloy grids, waste acids and pastes. Among them, the pastes mainly comprise lead oxide (∼9%), lead dioxide (∼28%), lead sulfate (∼60%) and a small amount of lead (∼3%) (Zhu et al., 2012a).
The recovery of lead from spent lead acid battery paste (SLP) is not only related to the sustainable development of the lead industry, but also to the sustainable evolution environment.
With the wide application of lead acid battery, spent lead acid battery has become a serious problem to environmental protection and human health. Though spent lead acid battery can be a contaminant if not handled properly, it is also an important resource.
Lead acid batteries (LABs) have been widely used in transportation, energy storage, communication equipment, and national economy owing to their excellent properties, such as low cost, great safety, and excellent electrochemical performance [1, 2].
