Reshaping the future of battery waste: Deep eutectic solvents in Li-ion battery recycling

Abstract

This review article explores the evolving landscape of lithium-ion battery (LIB) recycling, emphasizing the critical role of innovative technologies in addressing battery waste challenges. It examines the environmental hazards posed by used batteries and underscores the importance of effective recycling programs for sustainability. Deep eutectic solvents (DESs) have emerged as promising candidates for LIB recycling, offering advantages in selectivity, efficiency, and environmental sustainability. The review provides a comprehensive update on recent developments in DESs utilization for LIB recycling, focusing on processing conditions and mechanism peculiarities. It highlights the exponential growth of research in this area and the need for tracking trends and novel achievements. The article synthesizes the latest literature, discussing emerging trends, promising strategies, and areas for further research. It aims to contribute to advancing sustainable recycling solutions and reshaping the future of battery waste management.
