The lead–acid batteries represent about 60% of batteries sold in the entire world [1], [2], [3]. Lead is a material very easy to recycle and, provided that adequate procedures are implemented, the final product (secondary lead) is indistinguishable from the primary lead produced from ores. About 50% of the lead consumed worldwide is derived from recycled and

Two technological challenges in hydrometallurgical recovery process for spent lead-acid battery are recognized as: removal of impurity elements (such as Fe and Ba) and loop reuse for reducing dosage of leaching reagents.
In the last phase of lead-acid battery recycling, recyclers extract the lead powder and heavy metal components from the remaining battery remnants. This procedure can be executed in two distinct manners:
This process consists of four stages: (1) grinding of the battery to separate plastic, electrolyte and lead plates; (2) lead reduction in a rotary furnace; (3) separation of metallic lead...

At the heart of devices like smartphones, tablets and electric cars are rechargeable batteries, and at the heart of those is lithium. With demand growing, mining isn''t sustainable long-term, so
Once discarded, recent battery designs may be more prone to puncturing when compared to earlier models due to the lower mechanical integrity of modern casings [31]. Without proper containment, the metal nanostructures contained can then leach into the surrounding soil and water streams. Modelling studies to analyze the extent and pattern of environmental
A facile recovery route of spent lead-acid battery pastes, including efficient desulfurization and pH-controlled acid leaching, is proposed. Effects of two typical
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.

Recycling lead from spent lead-acid batteries has been demonstrated to be of paramount significance for both economic expansion and environmental preservation.
In 2022, the global production of recycled Pb surpassed 8.1 million tons, with a significant 85 % attributed to end-of-life lead-acid batteries [9]. Within discarded lead-acid batteries, Pb constitutes an overwhelming majority, comprising over 70 % by weight.
This process consists of four stages: (1) grinding of the battery to separate plastic, electrolyte and lead plates; (2) lead reduction in a rotary furnace; (3) separation of metallic lead...
In "Clean Recycling Process for Lead Oxide Preparation from Spent Lead–Acid Battery Pastes Using Tartaric Acid–Sodium Tartrate as a Transforming Agent," Ouyang et al. present a novel desulfurization-calcination procedure. Sulfur removal of LAB paste is experimentally conducted using tartaric acid and sodium tartrate to produce a lead
Projections indicate that discarded LIBs will exceed 11 million tons by 2030, considering their limited lifespan (typically 5–10 hydrometallurgy utilizes strong acid/alkali as leaching reagents, requiring multiple intricate stages and complex procedures to obtain high-purity products, accompanied by the generating tremendous wastewater [15], [16]. Conventional
