Electrosorption　is　generally　defined　as　adsorption　on　the　surfaces　of　charged　electrodes　by　applying　potential　or　current.　Electrosorption　deionization　method　is　a　low-pressure　non-membrane　deionization　process,　with　the　potential　to　be　a　low　energy　cost　alternative　for　desalination　in　the　future.　In　this　paper,　the　principle　and　mechanism　of　the　electrosorption　deionization　method　are　discussed,　the　materials　and　properties　of　the　electrode　used　in　electrosorption　process　are　summarized　and　the　application　and　prospect　of　this　promising　desalination　method　are　reviewed.
