As already mentioned, lead-acid battery recycling has a long tradition, especially in industrialised countries. The battery and scrap trade takes back spent batteries free of charge or even pays the metal value.
The lead acid battery has been widely used in automobile, energy storage and many other fields and domination of global secondary battery market with sharing about 50% . Since the positive electrode and negative electrode active materials are composed of PbO 2 /PbSO 4 and Pb/PbSO 4, lead is the most important raw material of lead acid batteries.
Typically, the recycling technologies for the recovery of lead from spent lead paste can be based on both hydrometallurgical and pyrometallurgical processes. Recycling through hydrometallurgy basically consists of the acid or base leaching of scrap to put the metals in a solution [ 2, 4 ].
The innovative cleaner metallurgical process for one-step extraction of lead from spent lead-acid battery paste via reductive sulfur-fixing smelting is technically feasible. This new technique is characterized by high comprehensive recovery of valuable metals, elimination of SO 2 emission, energy conservation and environment-friendly.
Since the positive electrode and negative electrode active materials are composed of PbO 2 /PbSO 4 and Pb/PbSO 4, lead is the most important raw material of lead acid batteries.
