New energy materials and technologies are developing rapidly, and the sales of electric vehicles are increasing significantly. The cathode material is the core of electric vehicle batteries. The production of electrode precursors generates a large amount of wastewater. Power lithium-ion battery precursor wastewater is highly toxic to the ecosystem and human health. For wastewater that cannot be treated biologically and for resource recovery, membrane technology demonstrates superior performance.The objective of this paper is to comprehensively organize and summarize the role of membrane processes in treating precursor wastewater from power lithium-ion batteries for water recovery and resource utilization. Firstly, by analyzing the sources and characteristics of various precursor wastewater and understanding the fundamentals of membrane technologies, this study aims to summarize the ability of different membrane processes to treat contaminants in precursor wastewater from power lithium-ion battery production. The performance of membrane filtration in removing heavy metals, recovering valuable salts, and water recycling is also discussed. Furthermore, the article emphasizes membrane fouling issues and reviews various strategies for mitigating contamination. Ultimately, the possible pathways for the resource reuse of power lithium-ion battery precursor wastewater were also proposed.
