Recycling of End-of-Life Lithium-Ion Batteries, Part II: Laboratory-Scale Research Developments in Mechanical, Thermal, and Leaching Treatments

摘要

Lithium-ion batteries (LIBs) are an essential energy storage device for many advanced electronics used in our everyday lives, from cell phones and laptops to medical devices and electric vehicles. Despite their continued widespread adoption, a method to recycle and reuse end-of-life (EOL) LIB materials is an area still under active development. Numerous hydrometallurgical methods have been explored to achieve a high extraction yield and effective separation of metal components. In the second part of this two-part review, we focus on recent developments made in laboratory-scale studies, namely developments in leaching chemistries, thermal treatment methods, and mechanical processing. A discussion on the advantages, disadvantages, and areas in need of future work is also presented.
