Sustainable battery materials via direct recycling

Modern lifestyles and population growth have greatly increased energy demand and consumption across various sectors. This surge in energy needs has accelerated the development of advanced energy storage technologies, particularly lithium-ion batteries, to power a wide range of applications, from electric vehicles and portable electronics to stationary energy storage systems, such as grid-scale battery installations. As a result, the rapid expansion of the global lithium-ion battery market presents significant economic and environmental challenges, driving a growing demand for metal resources. Consequently, there is strong interest in developing new technologies for recovering and recycling valuable materials from end-of-life lithium-ion batteries.
Compared to conventional high-temperature pyrometallurgical and hydrometallurgical methods, direct recycling of spent lithium-ion batteries offers a more attractive approach by regenerating electrode materials without breaking down their compounds. This method is not only more cost-effective but also less resource-intensive for the regeneration of Li-ion battery materials. Direct recycling provides a more sustainable and closed-loop strategy for electrode materials by bypassing the energy-intensive smelting and leaching steps. In this talk, current strategies and emerging technologies for direct recycling of end-of-life lithium-ion batteries will be discussed. Additionally, an efficient and sustainable method for the direct recycling of cathode active materials will be presented.
