Inverted Capacitive Deionization

Abstract

Inverted capacitive deionization (iCDI) is another important category of CDI which also employs the electrical double layer principle for desalination process. But different from conventional CDI, iCDI inverts the conventional CDI process which desalts without charging operation but recovers under charging mode. This point endows iCDI with unusual properties compared to conventional CDI. This chapter reviews the recent progresses in the iCDI field. We hope it will give some meaningful insights for readers to develop new materials or introduce some new concepts in this field.
