A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. The positive electrode consists of lead oxide. Both electrodes are immersed in a electrolytic solution of sulfuric acid and water.
A green, efficient, and short route for recovering metal lead from spent lead-acid batteries has a great advantage in both environmental protection and sustainable development of lead industry. This paper developed a new scheme to recover metal lead by direct electrolysis in (NH 4) 2 SO 4 solution with desulfurized lead paste.
In this investigation, two electrorefining... The recycling of lead acid batteries (LABs) comprises relevant concerns on the suitable methodologies to recover lead. In this investigation, two electrorefining processes, by using acidic and alkaline electrolytes, have been compared to determine the most significant results of both methodologies.
Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
The formation of this lead sulfate uses sulfate from the sulfuric acid electrolyte surrounding the battery. As a result, the electrolyte becomes less concentrated. Full discharge would result in both electrodes being covered with lead sulfate and water rather than sulfuric acid surrounding the electrodes.
Inspect the electrolyte level of each battery cell. Tip the battery forward to empty the electrolyte solution from the battery cells. Since the battery electrolyte contains sulfuric acid, make sure to capture all of the used electrolyte solution in an acid-resistant container.
