Within the framework of carbon neutrality, lithium-ion batteries (LIBs) are progressively booming along with the growing utilization of green and clean energy. However, the extensive application of LIBs with limited lifespan has brought about a significant recycling dilemma. The traditional hydrometallurgical or pyrometallurgical strategies are not capable to maximize the output value of spent LIBs and minimize the potential environmental hazards. Herein, to alternate the tedious and polluting treatment processes, we propose a high-temperature ...
