| Abstract Scope |
Innovations in materials processing based on fundamental thermokinetics have allowed the development of novel eco-metallurgical processes to produce materials substituting existing carbon-heavy-methods. A novel pyrometallurgical recycling process for end-of-life lithium ion batteries developed jointly by RDSŪ and Yonsei University is presented. Utilizing fundamental thermodynamic and kinetic principles, the reaction between cathode active materials with anode active materials within LIBs from cell phones and electric vehicles at defined temperatures, heating rates and oxygen partial pressures were systematically analyzed and interpreted. After processing, Ni-Co metal powders, Li2CO3, C, Cu, and Al-dross could be produced and separated, which could all be utilized in a wide range of industries. All highly valued elements from EOL-LIBs besides the electrolytes and the consumed carbon and aluminum during the reduction process could be recycled with over 90% retrieval and purity reaching 95% for the Li2CO3 products generated from the developed LIFE (Lithium ion Fast Extraction) ProcessŪ. |
