6 Frequently Asked Questions about “Lead powder in lead-acid batteries”
What is a green recycling process of discarded lead–acid battery?
Zhu X, Zhang W, Zhang L, Zuo Q, Yang J, Han L (2019) A green recycling process of the spent lead paste from discarded lead–acid battery by a hydrometallurgical process. Waste Manage Res 37 (5):508–515
What is the leaching electrolysis process for lead paste?
The leaching electrolysis process for lead paste can be categorized according to process flow into a three-stage process of desulfurization conversion-reduced leaching-electrodeposition and a two-stage process of direct leaching-electrodeposition. Here, this section is devoted to the electrodeposition procedure.
How can lead be recycled into PbO powder?
In addition, chemical transformations including leaching-crystallization [38, 39], leaching-calcination, leaching-pyrolysis, and hydrothermal desulfurization [23, 42, 43] have been developed to recycle lead resources into PbO powders.
How is Lead extracted from the electrolyzer?
Lead, PbSO 4, or other lead products are extracted from the bottom of the electrolyzer under forced stirring and current. The spent electrolyte could be further purified as pure electrolyte, which could then be reused in the production of LABs.
Can a bagged cathode be used to produce metallic lead?
Wang et al. proposed an innovative, ecologically friendly, and low-cost strategy for producing metallic lead via direct electroreduction of SLP with bagged cathode in Na 2 SO 4 electrolyte (Fig. 5) . The current efficiency and lead recovery are enhanced by the bagged cathode.
Why do lead products on the cathode have low levels of impurities?
Since most of the metal impurities have been removed during the hydrometallurgical leaching process, the obtained lead products on the cathode after electrowinning usually contain low levels of impurities, where the contents of metal impurities mainly depend on their amounts in electrolyte and electrodeposition potential compared to Pb.
