Lead-Acid Battery Manufacturing 1. Lead-acid battery manufacturing involves several processes that may generate lead-containing dust, lead oxide particles, fumes, sulfuric acid mist, wastewater and other industrial contaminants. 2. Lead-containing dust generated during processes such as paste mixing, plate handling, brushing and related operations should be effectively captured and controlled to reduce airborne contamination and occupational exposure. 3. Sulfuric acid used in lead-acid battery production is highly corrosive. Acid dilution, filling, formation and related processes require suitable corrosion-resistant equipment, ventilation and appropriate safety measures. 4. Different production stages require different environmental control technologies. Dust collection, acid mist treatment, wastewater treatment and process-water preparation should be selected according to the specific operation and contaminant. 5. Appropriate personal protective equipment, engineering controls and operating procedures should be used according to the process hazards and applicable workplace safety requirements.
1. In lead-acid battery manufacturing, lead oxide, water, sulfuric acid and formulation additives are mixed under controlled conditions to produce the active-material paste used for battery plates. 2. Handling and feeding lead oxide and other dry ingredients can generate lead-containing dust, while the subsequent mixing process may produce moist or acidic airborne contaminants depending on the process conditions. 3. As the paste mixing process progresses, the collected contaminants may become acidic, moist and potentially sticky, which should be considered when selecting the extraction and filtration method. 4. For paste mixing applications involving moist, sticky or acid-containing contaminants, a suitable wet collection or scrubbing system can be considered according to the actual process conditions, contaminant characteristics and required emission performance.
