Lead acid battery scraps

Lead-acid batteries are secondary or rechargeable batteries used widely in cellular phones, computers etc. Based on the method of construction there are two types of lead-acid storage batteries. They are flooded and sealed lead acid batteries. The battery comprises of metal grid, electrode paste, sulphuric acid, connectors and poles of lead alloy, and grid separators made up of PVC. The battery components are contained in a plastic housing which is heat and corrosion resistant. The typical lead-acid storage scrap batteries contain 25-30% of lead alloy components like grid, poles. It contains 35-45% of electrode paste which includes fine particles of lead oxide and lead sulphate. The scrap also contains 10-15% of sulphuric acid, 5-8% of polypropylene, 4-7% of other plastics like PVC, PE etc, 1-3% of ebonite and less than 0.5% of other materials like glass. Drained lead acid battery scrap consists of whole drained lead or acid batteries. Hence a number of raw materials are available in the battery scraps. Hence proper battery disposal and recycling is required to make efficient use of resources.
