Whether it''s your car, boat, or even a household appliance, a dead battery can be frustrating. One common cause of battery failure is sulfation, a buildup of lead sulfate crystals on the battery plates. But before you rush out to buy a new battery, there''s a cost-effective solution you can try: desulfating the battery with a charger.
This paper reports a new method of direct recovery of highly pure lead oxide (PbO) from waste lead pastes and lead grids of spent lead–acid batteries via catalytic conversion, desulfurization, and recrystallization processes in sequence. On the basis of the analytical results of lead (Pb) and lead dioxide (PbO2) contents in the scrap lead paste, a …
