Recent advances in green deep eutectic solvents for lithium-ion battery recycling: A perspective on bibliometric analysis.

The rapid growth of electric vehicles worldwide has resulted in a significant increase in the demand for lithium-ion batteries (LIBs), thereby accelerating the development of the LIBs recycling industry. Currently, the predominant methods for recycling spent LIBs include pyrometallurgical, hydrometallurgical, and direct recycling techniques, each with its own advantages and disadvantages. To enhance the recycling efficiency of cathode metals from spent LIBs while promoting environmental sustainability, green deep eutectic solvents (DESs) have attracted scholarly interest.
