vehicles, and energy storage [2-6]. Lead acid batteries occupy more than 70% of the global secondary battery market share [7]. Correspondingly, spent lead acid batteries dominate the raw materials of the secondary lead, accounting for over 85% of the wastes [8]. Thus, spent lead acid batteries can be viewed as the most important renewable lead resources. If being treated inappropriately, spent lead......
