摘　　要：电容去离子技术(Capacitivedeionization,CDI)是一种新兴的脱盐技术,通过在电极两端施加外加电场除去水中带电离子或分子,由于其具有低能耗和可持续性的特点而备受关注。储能电池领域的迅猛发展实现了阳离子储存从双电层作用为代表的碳材料到法拉第电极材料的跨越。相较于传统碳材料,法拉第材料的脱盐性能有了显著提升。目前,CDI中针对阴离子,特别是氟离子,高效去除的电极材料研究较少。本文从CDI装置构型的发展演变出发,系统梳理了CDI中关于除氟电极材料的分类,对比不同类型除氟电极材料的特点,并总结氟离子的去除机理以及氟离子电池领域电极材料的研究进展,为CDI除氟电极与装置构型的设计开发提供了理论基础和研究思路。The capacitive deionization(CDI) is an emerging desalination technology that removes charged ions and molecules from water by applying an applied electric field at both ends of the electrode,which is concerned due to its low energy consumption and sustainability.Because of the rapid development in the field of energy storage batteries,the cationic electrode materials have leaped carbon materials,represented by the bilayer mechanism of action,to Faraday electrode materials,resulting in a significant improvement in the desalination performance of CDI.Currently,less research attention has been paid to electrode materials for the efficient removal of anions,especially fluoride ions in CDI.This paper systematically sorted out the classification of fluoride removal electrode materials in CDI,compared the characteristics of different types of fluoride removal electrode materials,summarized the mechanism of fluoride ion removal and the research progress of electrode materials in the field of fluorine ion battery,and provided the theoretical basis and research ideas for the design and development of CDI fluoride removal electrodes and device configurations.
