摘要:

随着新能源领域对锂资源需求的持续增长,开发高效的锂提取技术变得及其重要。然而,由于其高能耗和可能引发的二次污染问题,传统的锂提取和回收技术具有实际应用和发展的局限性。电容去离子(CDI)技术作为一种新兴的锂提取技术,在效率、成本效益和能源消耗方面展现出巨大的潜力。本综述从文献计量入手,剖析了CDI提锂的关键研究主题,进而全面总结了在CDI提锂技术中电极材料的最新进展,并探讨了使用这些材料构建的各种CDI系统类型。本研究详细阐明了CDI系统中用于锂资源回收的主要电极材料——水系锂离子电极材料(包括LiFePO4、LiMn2O4、LiNi1/3Co1/3Mn1/3O2等)及其修饰材料(包括碳纳米管、石墨烯、MOF等)。此外,本文讨论了通过不同的电容去离子(CDI)系统提高锂提取效率,并评估了各种先进电极材料在这些系统中的性能。文末强调了机器学习在CDI提锂领域的应用潜力,并期望本研究将为未来开发基于CDI的高效锂提取系统提供坚实的理论基础和实践指导。

Abstract:

Efficient technologies for lithium extraction are progressively pivotal in response to the growing requirement for lithium in new energy applications. However, due to its high energy consumption and possible secondary pollution problems, traditional lithium absorption and recovery technologies, are limited in practical application and development. Capacitive deionization (CDI) demonstrates significant potential for lithium extraction with regard to efficiency, cost-effectiveness, and energy consumption. This review commences with bibliometric analysis to dissect the key research topics of lithium extraction via CDI, and presents a complete synopsis of recent advances in electrode materials for lithium extraction using CDI technology, along with various types of CDI systems that utilize these materials. This study elucidates in detail the main electrode materials used in CDI systems for lithium resource recovery——aqueous lithium ion electrode materials (including LiFePO4, LiMn2O4, LiNi1/3Co1/3Mn1/3O2) and their modification materials (including carbon nanotubes, graphene, MOFs). In addition, this paper discusses the improvement of lithium extraction efficiency through different CDI systems and evaluates the capability of various advanced electrode materials in these systems. The end of the paper emphasizes the application potential of machine learning in the domain of lithium extraction via CDI. The study is anticipated to deliver a strong theoretical basis and practical recommendations for advancing efficient lithium extraction systems that utilize CDI.
