Used lead-acid batteries generally come from scrapped automobiles and electric bicycles. Based on structural and functional differences, lead-acid batteries can be divided into starting (flooded) lead-acid batteries, motive (starved electrolyte) lead-acid batteries, and other types. Spent lead-acid batteries contain 24% to 30% (by mass) of lead alloy grids, terminals, and other alloy components. Grids dismantled from spent lead-acid batteries contain a large amount of lead. After separation, they are directly sent to furnaces for smelting. The smelting temperature is approximately 900 to 1000°C. As there is some residual lead mud on the grids, pollutants such as lead dust and lead slag are generated during the smelting process. This dataset applies to the smelting process of grid plates from waste lead-acid batteries.
