new approach to recover anode materials from spent li

A Rapid and Facile Approach for the Recycling of

By a combination of thermal decomposition and dissolution steps, spent NCM could be converted into Li 2 CO 3 and a transition metal oxalate blend, which served as precursors for new NCM. Importantly, it was also possible to individually separate each transition metal during the recycling process, thereby extending the utility of this method to a wide variety of NCM compositions.
