A Novel recycling process for Spent Li-ion Batteries

The rapid growth of the global lithium-ion battery market poses economic and environmental challenges leading to an increased demand for metal resources. Indeed, the number of spent batteries which are categorized as hazardous and potentially harmful waste has increased dramatically in recent years. Consequently, recycling of spent batteries holds significant importance and emerges as a vital strategy to recover and reintegrate the recovered materials into the battery supply chain. Indeed, recycling of spent Li-ion batteries has attracted a lot of attention because it raises questions about sustainability, resource, and energy security. Recycling mitigates the scarcity of strategic elements used in battery production and reduces associated manufacturing expenses.
Several technologies are used for the recycling of spent Li-ion batteries such as pyrometallurgical, hydrometallurgical, and direct recycling. The concept of direct recycling has has emerged as an innovative and a more sustainable approach because it offers several advantages compared to other traditional recycling processes that require high energy consumption and chemicals utilization. Indeed, direct recycling ensures high recovery rate of cathode active materials while employing simpler processes, compared with traditional recycling processes. In this talk, the current strategies, and emerging technologies in the recycling of spent Li-ion batteries will be discussed. In addition, an efficient, and eco-friendly method for the direct recycling of cathode active materials material will be presented.
