Towards Sustainable Direct Recycling: Unraveling Structural Degradation Induced by Thermal Pretreatment of Lithium-Ion Battery Electrodes.

ABSTRACT: As the demand for lithium-ion batteries (LIBs) continues to increase, there is a growing focus on recycling these battery wastes. Among the existing recycling methods, direct recycling is considered a promising approach, because it allows waste to be returned directly to production. One crucial step in this process is the pretreatment, which involves separating the active materials from the current collector. Thermal treatment provides a feasible and effective approach for achieving this separation. Nonetheless, concerns persist regarding the potential impacts of this process on the structure. This study aims to examine the effects of thermal treatment on the separation efficiency and crystal structure of fresh and cycled NMC (LiNi_0.6Co_0.2Mn_0.2O₂
