A Rapid and Facile Approach for the Recycling of High-Performance LiNi_1-x-y Co_x Mn_y O₂ Active Materials.

ABSTRACT: The demand for lithium-ion batteries has risen dramatically over the years. Unfortunately, many of the essential component materials, such as cobalt and lithium, are both costly and of limited abundance. For this reason, the recycling of lithium-ion battery electrodes is crucial to ensuring the availability of such resources and protecting the environment. Herein, a simple and scalable recycling process was developed for the prototypical cathode active material Li_1.02 (Ni_0.8 Co_0.1 Mn_0.1 )_0.98 O₂ (NCM-811). By a combination of thermal decomposition and dissolution steps, spent NCM could be converted into Li₂ CO₃ and a transition metal oxalate blend, which served as precursors for new NCM. Importantly, it
