The rapid increase in electric vehicle (EV) adoption globally poses significant environmental and resource management challenges, especially concerning the lifecycle of lithium-ion batteries. This paper explores the sustainability of remanufacturing, reusing, and recycling e-mobility batteries to mitigate environmental impacts and enhance resource efficiency. Utilizing data from the International Energy Agency and predictive models, the study projects a tripling of EV numbers over the next decade. It evaluates various battery end-of-life (EoL) strategies through technical, economic, and environmental analyses. Findings reveal that recycling batteries significantly reduces reliance on scarce virgin materials and prevents up to six tons of CO2 emissions per ton, saving \$300 per ton based on current carbon credit values. Figure 3 further demonstrates a reduction of up to 60% in CO2 emissions, 40% in energy consumption, and 50% in waste generation from recycling processes. Additionally, the paper highlights promising technologies like direct recycling that preserve more of the battery’s original materials. Policy recommendations to support the recycling industry include incentives for using recycled materials and stricter disposal regulations. The integration of renewable energy sources into the recycling process also decreases the carbon footprint of these operations. This study offers a framework for policymakers and industry stakeholders to foster a circular economy in the battery industry, underscoring the urgent need for robust battery EoL strategies in response to rising EV adoption.
