Abstract
Pretreatment process is essential in lithium-ion battery (LIB) recycling. The pretreatment of spent LIB module pack typically includes disassembly, cell discharge, dissociation of electrode material using physical/chemical methods, and sorting of electrode material and current collector materials. Its main purpose is to separate the cathode material with the highest recycling value from other components of the battery, especially aluminum foil, enabling the following regeneration or efficient extraction of valuable metals by the hydrometallurgical process. Although some review articles have discussed the pretreatment methods of spent LIBs, to the best of our knowledge, few have specifically focused on the liberation of cathode material to date. Recently, significant progress has been made in this field, with advancements in physical fragmentation and grinding, organic solvent immersion, alkaline solution immersion, and heat treatment. Moreover, conventional heat treatment methods, especially pyrolysis, have seen notable improvements. Emerging technologies such as deep eutectic solvents (DES), high-voltage pulsed discharge, electrical separation, and acid-assisted separation have also garnered attention. Given the growing interest in LIBs recycling, the demand for comprehensive information on this topic is increasingly urgent. This state-of-the-art review aims to provide insights into the development of spent LIBs recycling technology.
期刊介绍:
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
