    Abstract: The rapid development of the electric vehicle industry has led to a surge in demand for power lithium-ion batteries, making natural cobalt, lithium, and nickel scarce mineral resources. To promote the sustainable development of the electric vehicle industry and solve the problems of environmental pollution as well as resource scarcity caused by lithium-ion batteries, it is extremely imperative to realize the green recycling of end-of-life electric vehicle lithium-ion batteries. This article systematically reviewed and evaluated the recycling process of lithium-ion batteries from electric vehicles, which focuses on discharging, dismantling, stripping, separation, metallurgy and other operations. The influence of different operation methods on stripping, sorting, metallurgy and other effects is analyzed from the perspectives of technology research and development and industrial application, and the research progress and main problems of each operation link are discussed. The future development of recycling lithium-ion batteries is prospected, which lay the foundation for the green and efficient recycling of spent lithium-ion batteries.
