Recycling and Disposal of Lithium-Ion Batteries Utilized in Electric Vehicles: A Review

Abstract: The rapid proliferation of electric vehicles (EVs) has significantly contributed to reducing greenhouse gas emissions and advancing sustainable transportation systems. Central to the functionality of these EVs are lithium-ion batteries (LiFePO4), known for their high energy density and long lifespan. However, as the EV market continues to expand, the growing issue of battery waste management presents considerable environmental and economic challenges. This paper provides a comprehensive overview of the three main types of lithium-ion batteries utilized in electric vehicles, namely, Lithium Iron Phosphate (LFP), Nickel Manganese Cobalt (NMC) and Nickel Cobalt aluminum (NCA) batteries. It examines the challenges and opportunities of lithium-ion battery recycling and disposal within the broader context of the ongoing energy crisis. As the demand for clean energy technologies intensifies, the sustainable management of battery waste becomes crucial to ensure the long-term viability of renewable energy systems and addressing resource scarcity. This review explores the complexities involved in lithium-ion battery recycling and disposal. It discusses the four prominent recycling methods that are available and in practice as of 2024. The advantages and disadvantages of each of the methods are carefully evaluated and discussed thoroughly in the paper. The findings underscore the urgent need for collaborative efforts among policymakers, industry stakeholders, and researchers to develop comprehensive strategies that support circular economy principles, enhance resource efficiency, and promote environmental stewardship in the transition shift toward a sustainable energy future.
