Considering that the lead–acid battery dominates consumption of the element, around 80% of world lead output, it is not surprising to find that secondary lead sourced from batteries is the major contributor to the world''s annual lead production of 8.4 million tons. The recycling of lead–acid batteries has been an established practice ever since the introduction of the battery

The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O. Overall: Pb + PbO 2 +2H 2 SO 4 → 2PbSO 4 + 2H 2 O. During the

Lead is also widely used in the production of lead-acid batteries, as it is able to store large amounts of energy and is able to withstand the high charging and discharging rates that are common in these applications. Lead is also used in the production of radiation shielding, as it is able to absorb and block radiation.

A facile recovery route of spent lead-acid battery pastes, including efficient desulfurization and pH-controlled acid leaching, is proposed. Effects of two typical desulfurizers (NaOH and Na 2 CO 3 ) on desulfurization efficiency and removals of major impurities (Ba and Fe elements) were comparatively investigated for the first time.
A lead acid battery typically consists of several cells, each containing a positive and negative plate. These plates are submerged in an electrolyte solution, which is typically a mixture of sulfuric acid and water. The plates are made of lead, while the electrolyte is a conductive solution that allows electrons to flow between the plates. The Chemistry Behind
General advantages and disadvantages of lead-acid batteries. Lead-acid batteries are known for their long service life. For example, a lead-acid battery used as a storage battery can last between 5 and 15 years, depending on its quality and usage. They are usually inexpensive to purchase. At the same time, they are extremely durable, reliable
