| Abstract Scope |
For a smooth transition to a CO2-neutral society, spent lithium-ion batteries (LIBs) must be recycled. Swerim has in recent years made great efforts in this field. This paper will summarize the major projects and highlight their major results. In the pyrometallurgical study, an optimized pyrometallurgical recycling process was developed and demonstrated in a pilot electric arc furnace (8-tonne scale). The developed process demonstrated a high recovery of cobalt and nickel of > 98%, and most of the lithium was recovered into a Li-rich dust fraction which could be upgraded into lithium carbonate by carbonated water leaching. In the shredding and thermal treatment study, a homemade simulator was constructed to simulate the combined mechanical and thermal treatment of spent LIBs cells. Studies were conducted to examine the possibility of recovering electrolyte components as well as to understand the mechanisms behind the formation of gases generated during shredding. |
