This review delves into recent innovations in cathode material recycling from LIBs, focusing on methodologies that not only reclaim materials but also restore their functionality for reuse. Highlighted are cutting-edge techniques such as an electrochemical relithiation process, which rejuvenates spent cathode materials to equal the performance of new ones. At the forefront of these sustainable practices is the concept of direct regeneration via direct recycling, offering an economically viable and environmentally friendly approach to mend degraded cathodes. Such progress signals a shift away from conventional metallurgical methods toward intelligent regeneration, representing a significant step forward in the sustainable recycling of LIBs. This review provides a brief analysis of these novel recycling processes, illustrating their ability to transform spent batteries into valuable resources, mitigate environmental harm, and foster a circular economy within the realm of energy storage.enLithium-Ion Battery RecyclingCathode MaterialRegenerationRelithiationDirect RecyclingconferenceObject
