Lead-Acid Battery Technology. Lead-acid batteries employ [lead electrodes] and [sulfuric acid electrolyte] to store and discharge energy. A typical battery cell consists of two lead plates; one is covered in lead dioxide while the other plate is made of lead. The two plates are immersed in a sulfuric acid electrolyte solution that acts as a
Improper waste lead-acid battery (LAB) disposal not only damages the environment, but also leads to potential safety hazards. Given that waste best available treatment technology (BATT)...
Overview Approximately 86 per cent of the total global consumption of lead is for the production of lead-acid batteries, mainly used in motorized vehicles, storage of energy generated by photovoltaic cells and wind turbines, and for back-up power supplies (ILA, 2019). The increasing demand for motor vehicles as countries undergo economic development and

In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method. The structure of quicklime, slaked lime, and resultant residues were measured by X-ray diffraction. The obtained results show that
Effective removal of both, acidity and lead in a single step was achieved in only 25 minutes of electrolysis time with iron electrodes and a mixed supporting electrolyte solution containing 0.03 M Na2SO4 and 0.003 M KCl. Keywords: Acid lead battery wastewater, aluminum and iron sacrificial electrodes, electrochemical coagulation. 1. Introduction .
Secondary lead facilities in North America mainly produce lead alloys by recycling end of life lead bearing materials, primarily lead acid batteries. Throughout the lifecycle, these batteries undergo thousands of charge–discharge cycles that cause degradation of the electrically active components. As a result, lead and the alloying elements

Secondary lead mainly refers to the lead recovered from discarded lead acid battery, lead dust, lead pipe, lead glass of liquid crystal display (LCD), and slag from lead smelting process. Among the secondary lead resources, the spent lead acid battery was listed as relatively easier for collection and transportation. Generally estimated, spent/discarded lead acid

Lead Acid Batteries (LABs) are vital for reliably powering many devices. Globally, the LAB market is anticipated to reach USD 95.32 billion by 2026, with Europe having the second biggest market share has been
Physical treatment methods can remove (up to 90–99%), chemical treatment methods can remove (up to 95–99%), and biological treatment methods can remove (up to 40–99%) Pb from wastewater. Based on the efficiency range of each method, chemical treatment methods appear to be the most efficient for the removal of Pb from wastewater.
In this study, a strong acid gel cation exchanger (C100) impregnated with hydrated ferric hydroxide (HFO) nanoparticles (C100-Fe) was synthesized, characterized, and
The results indicated that mixed smelting technology (MST), pre-desulfurization and multi-chamber smelting technology (PD-MCST), and direct smelting technology (DST) were found to perform well and were therefore deemed optimal for waste LAB disposal at this stage.
It is evident that the segregation and independent treatment of the most polluting effluents from dismantling and washing lead-acid batteries means that much of the rest of the effluents can be discharged; this therefore simplifies their treatment and minimises the environmental impact.
The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).
Lead-acid batteries (LABs) have been undergoing rapid development in the global market due to their superior performance , , . Statistically, LABs account for more than 80% of the total lead consumption and are widely applied in various vehicles .
The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the advanced processes already being implemented by some environmental managers.
The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.
