 The rapid increase in electric vehicle adoption has led to a surge in demand for lithium ion batteries, LIBs, which contain rare metals and toxic electrolytes. To ensure sustainable use of these batteries, they must be effectively managed at end of life, either through reuse in less demanding applications or through recycling. This review discusses the various options available for managing spent LIBs, including battery second use, repair of electrodes, and material recovery. Current technologies, environmental impacts, and economic feasibility are also considered. Examples of pilot and industrial scale adoption of the processes are provided.
