The characteristics of a single chemistry together with a standard design for all lead-acid cells result in a simple recycling process. Fig. 2 plots the cell composition in a NMC622 Li-ion cell and a lead-acid battery. Lead-acid batteries have few components, making them easy to recycle.
Secondary lead production is almost entirely dependent on the recycling of spent lead-acid batteries (Fig. 7) [2, 73]. After removing the acid, the batteries are crushed to separate lead from the plastic. The lead can be separated in a lead metal fraction and a lead oxide fraction by a mechanical process .
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
