What Are the Main Sources of Pollution in Lithium-Ion Battery Production?Raw Material Extraction: Raw material extraction generates considerable pollution. Chemical Waste: Chemical waste is another significant source of pollution. End-of-life Disposal: End-of-life disposal presents environmental challenges as well.
These metal materials can generate pollutants in the process of material exploitation, battery production, and battery recycling or disposal.

The manufacturing process begins with building the chassis using a combination of aluminium and steel; emissions from smelting these remain the same in both ICE and EV. However, the environmental impact of battery production begins to change when we consider the manufacturing process of the battery in the latter type.
However, as we've examined, the battery-making process isn't free of environmental effects. In this light, this calls for sector-wide improvements to achieve environmentally friendly battery production as much as possible. There's a need to make the processes around battery making and disposal much greener and safer.
However, the environmental impact of EV batteries is a very complex issue, not only affected by material exploitation and battery manufacturing and production methods, but also by battery transportation, usage, recycling, or disposal methods (Wang et al., 2020, Zhiyong et al., 2020, ISO, 2006a).
The main sources of pollution in lithium-ion battery production include raw material extraction, manufacturing processes, chemical waste, and end-of-life disposal. Addressing the sources of pollution is essential for understanding the environmental impact of lithium-ion battery production.
Addressing the pollution and environmental impact of lithium-ion battery production requires a multi-faceted approach. Innovations in battery technology, responsible sourcing of raw materials, and enhanced recycling efforts are vital.
