Abstract: The pyrometallurgical regeneration is associated with high energy consumption，high melting metals volatilization， high pollution emissions，and other shortcomings.Therefore，more attention has been paid to lead paste desulfurization conversion process of waste lead-acid battery.Several commonly used measurement methods for sulfur in the lead paste from waste lead-acid battery were introduced，and their basic principles were mainly introduced.Recent research progress of the lead paste desulfurization process at home and abroad was summarized in detail.The development trend of lead paste desulfurization process was also predicted.

Key words: waste lead-acid battery；lead paste；desulfurization
