摘要：
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. © 2021, China Science Publishing & Media Ltd.
