| description | In the context of the rising demand for electric storage systems, lithium–sulfur batteries provide an attractive solution for low-weight and high-energy battery systems. Considering circular economy for new technologies, it is necessary to assure the raw material requirements for future generations. Therefore, metallurgical recycling processes are required. Since lithium is the central and most valuable element used in lithium–sulfur batteries, this study presents an environmentally friendly and safe process for lithium recovery as lithium carbonate. The developed and experimentally performed process is a combination of thermal and hydrometallurgical methods. Firstly, the battery cells are thermally deactivated to mechanically extract black mass. Then, water leaching of the black mass in combination with using CO<sub>2</sub>, instead of emitting it, can mobilize lithium by >90% as solid product. |
