Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs)—lead–acid batteries are made from abundant low-cost materials and nonflammable
solution to the environmentally sound management of waste lead-acid batteries. 1 Heinstock, ICME study 2. 1. HISTORICAL BACKGROUND 7. The physical and chemical properties of lead such as its malleability and resistance to corrosion were already known from the ancient civilizations. Lead has been mined and smelted, indeed, for at least 8,000 years. This is
Lead-acid batteries (LABs) have become an integral part of modern society due to their advantages of low cost, simple production, excellent stability, and high safety performance, which have found widespread application in various fields, including the automotive industry, power storage systems, uninterruptible power supply, electric bicycles, and backup
An average battery can contain up to 10 kilograms of lead. Recycled lead is a valuable commodity for many people in the developing world, making the recovery of car batteries [known as Waste Lead-Acid Batteries (WLAB) or Used Lead-Acid Batteries (ULAB)] a viable and profitable business which is practiced in both formal and informal sectors
As part of the Lead Battery 360° program we aim to promote a better understanding of what constitutes responsible lead battery manufacturing and recycling. Over the years we have developed guidelines and tools to allow

China produces a large number of waste lead-acid batteries (WLABs). However, because of the poor state of the country''s collection system, China''s formal recycling rate is much lower than that of developed countries and regions, posing a serious threat to the environment and human health.
According to the 2015 report on lead-acid battery by Chinese Association of Battery Industry (Zhao and Cao, 2015-11-24), disposal of lead-containing acid increases significantly by year in the past 12 years and it only starts to decrease from recently (Fig. 1 b). Lead is of highly toxic, poisoning almost every organ through blood. Long-term

Over the years we have developed guidelines and tools to allow stakeholders to gain a fundamental understanding of the key principles required to recycle lead batteries in a manner that
As noted in the Global Battery Alliance (GBA) report A Vision for a Sustainable Battery Value Chain in 2030: "[A] vision of the battery value chain is incomplete without providing a perspective of the other large battery market segment: lead-acid batteries (LAB). In 2018, approximately 72% of the world rechargeable battery capacity (in GWh) was
Recycling lead from waste lead-acid batteries by the combination of low temperature alkaline and bath smelting
Another important performance factor for lead–acid batteries is self-discharge, a gradual reduction in the state of charge of a battery during storage or standby. The self-discharge takes place because of the tendency of battery reactions to proceed toward the discharged state, in the direction of exothermic change or toward the equilibrium. The

Therefore, clarifying the life distribution of waste lead batteries by analyzing accurate user behavior can help promote the gathering of accurate statistics on end-of-life waste lead batteries and provide data support for overall government planning and supervision, as well as improving the geographical distribution of recycling enterprises.
With improved understanding of the status, circulability of lead in the whole life cycle of lead-acid battery is subsequently calculated. The main conclusions can be given as follows: 30–40% of the spent lead-acid battery is recycled through companies without a certificate for handling hazardous waste.
Subsequently, the MIIT and MEE issued new conditions for companies entering the lead battery and the secondary lead industry in 2012, stipulating that newly renovated and expanded recycling enterprises entering the sector must have a minimum capacity of 50 kt/a.
Ingestion of vegetables and inhalation are the main exposure pathways. In recent years, environmental pollution and public health incidents caused by the recycling of spent lead-acid batteries (LABs) has becoming more frequent, posing potential risk to both the ecological environment and human health.
As for the recycled waste batteries, the primary lead industry can take lead concentrate or higher grade lead concentrate after sintering as the main raw material, and lead-containing waste in waste lead-acid batteries such as lead paste from a small number of WLABs as auxiliary ingredients.
To a broader level, the entire life cycle of lead-acid battery needs to be considered that are raw materials production, lead-acid battery design, production and consumption, end-of-life process including collection of spent LABs and recycling or reuse of lead for lead acid battery (Fig. 9) (Sun et al., 2017).
