Abstract
ABSTRACT Direct recycling has emerged as a promising alternative to existing recycling methods due to its simplicity and cost-effectiveness. However, its scalable application remains a subject of debate, primarily due to the complexity of mixed degraded cathode materials in practice. The reason is that degraded materials with different compositions are extremely difficult to be repaired to produce cathode materials with uniform composition and performance. Herein, we have successfully realized direct regeneration of mixed heterogeneous degraded LiNi0.5Co0.2Mn0.3O2 from different sources on an industrial scale. First, uniform contact lithiation is achieved through the van der Waals force between…
