Used lead-acid batteries generally come from scrapped automobiles and electric bicycles. Depending on structural and functional differences, lead-acid batteries can be categorized into starting (flooded) lead-acid batteries, motive (starved electrolyte) lead-acid batteries, and other types. After dismantling, the main components of waste lead-acid batteries include: 30% to 40% (by weight) waste lead paste, 24% to 30% (by weight) lead alloy grids and terminals, 22% to 30% (by weight) plastic and other organic materials, and 11% to 30% (by weight) electrolyte. The process represented by this dataset involves spent lead-acid batteries entering the dismantling workshop, followed by dismantling, piercing, crushing, and hydraulic separation to obtain electrolyte, lead paste, grid plates, and plastic separators. This dataset is applicable to the dismantling process of spent lead-acid batteries.
