Batteries account for more than 80 per cent of the global demand of lead. Improper recycling of used lead-acid batteries causes environmental pollution and health damage. The largest subsets of lead-acid batteries are for automotive applications (May, Davidson & Monahov, 2018).
Lead-acid batteries are the most widely and commonly used rechargeable batteries in the automotive and industrial sector. Irrespective of the environmental challenges it poses, lead-acid batteries have remained ahead of its peers because of its cheap cost as compared to the expensive cost of Lithium ion and nickel cadmium batteries.
For all battery technologies, the contribution of lead production to the impact categories under consideration was in the range of 40 to 80 % of total cradle-to-gate impact, making it the most dominant contributor in the production phase (system A) of the life cycle of lead-based batteries.
The technical challenges facing lead–acid batteries are a consequence of the complex interplay of electrochemical and chemical processes that occur at multiple length scales. Atomic-scale insight into the processes that are taking place at electrodes will provide the path toward increased efficiency, lifetime, and capacity of lead–acid batteries.
Inappropriate recycling operations release considerable amounts of lead particles and fumes emitted into the air, deposited onto soil, water bodies and other surfaces, with both environment and human health negative impacts. Lead-acid batteries are the most widely and commonly used rechargeable batteries in the automotive and industrial sector.
Lead-based batteries LCA Lead production (from ores or recycled scrap) is the dominant contributor to environmental impacts associated with the production of lead-based batteries. The high recycling rates associated with lead-acid batteries dramatically reduce any environmental impacts.

About the Lead Acid Battery
Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.
