In recent years, ion-selective capacitive deionization (CDI) technology has been used to selectively separate ions from multi-ion composition solutions. Innovative ion-selective electrode materials have been widely used in the fields of recovery of high-value ions and removal of toxic and harmful ions. Developments of electrode materials and their structure-chemical activity relationships were reviewed and analyzed. Moreover, anticipatory observations and challenges regarding the future of ion-selective CDI devices are discussed. Ultimately, this comprehensive review aims to provide meaningful insights and directions in the exploration for ideal ion-selective electrode materials, propelling further advancements in CDI systems.
