Important results from the project
The project aimed to enhance the recovery of valuable metals from spent LIBs using different approaches. Specific objectives included developing pretreatment methods to remove electrolyte and detect hazardous, separating graphite and recovery of Li without compromising recovery rates of Co, Ni, and Mn. The project was developed in phases, starting with basic principles and laboratory work and moving to pilot-scale verification, followed by sustainability and economic evaluations. All activities have been performed according to the project plan and the project goals met.
Expected long term effects
The NEXT-LIB developed processer to improve the existing ones for recycling of spent LiB with focus on Li, graphite and electrolyte. NEXT-LiB combined mineral processing, mechanical activation, pyrometallurgy, and hydrometallurgy to improve the processes. The project achieved recovery rates of up to 68% graphite, 86% Cu, and 84% Al, and up to 100% of Li, Co and Ni. Also methods for recovery of graphite and electrolyte have been developed and evaluated. The project outcomes contribute to a improved circular economy and reduced environmental impacts.
Approach and implementation
The NEXT-LiB project was coordinated by Swerim via numbers of project meeting both online and physically. The project activities were organized and carried out step by step as follows: -Comprehensive characterization works as to understand the black mass material with focus on binders. This is essential for development of pretreatment process for graphite recovery. -Prove of concept test works in lab scale -Prove of concept test works in upscaled reactors -Product and process evaluations both from the economic and environmental perspectives
