Advancements and Challenges in Lithium-Ion Battery Lifecycle Management Toward a Sustainable Circular Economy for Electric Vehicles

The increasing global shift towards electric vehicles (EVs) has led to a surge in demand for lithium-ion batteries (LIBs), which serve as the primary energy storage solution for modern EVs. However, with this growth comes significant challenges related to battery performance, sustainability, and end-of-life (EOL) management. This paper provides a comprehensive review of battery technologies, focusing on advancements in lithium-ion batteries, their degradation mechanisms, and the environmental impact of battery disposal. Additionally, it examines the challenges in EV battery recycling, including safety hazards, disassembly complexities, and economic feasibility. The study explores second-life applications of retired EV batteries in energy storage systems, microgrids, and hybrid renewable energy solutions, emphasizing their potential to extend battery usability while minimizing waste. Furthermore, advanced screening, refurbishment, and material recovery techniques are analyzed to improve resource efficiency and reduce the need for new raw material extraction. By proposing a systematic framework for sustainable battery lifecycle management, this research aims to promote a circular economy, optimize battery reusability, and support the transition towards a cleaner, more sustainable future in electromobility.
