The growing demand for lithium-ion batteries (LIBs) underscores the urgent need for efficient recycling technologies. This presentation explores the current landscape of LIB recycling, analyzing state-of-the-art metallurgical research validated through expert interviews. Key criteria such as economic viability, decarbonization potential, and technology readiness have been assessed to identify the most promising solutions. Our findings highlight Lithium First processes as the most advanced metallurgical approach, offering superior lithium recovery while optimizing resource efficiency. After optimization, these processes show strong potential for implementation at an industrial scale, enhancing sustainability and economic feasibility in LIB recycling.
