Research progress on hybrid capacitive deionization and faradic electrode materials
The basic principles of hybrid capacitive deionization(HCDI)and its development history are introduced.From the analysis of the principle and current situation of HCDI,it is concluded that the key of the research of HCDI lies in the electrode material.Thus,the current research status of faradic electrode materials including transition metal oxides,poly anionic compounds,and prussian blue analogs is system-atically reviewed.Based on the above analysis,it is suggested that the current research focus is still to im-prove the desalination ability and cycling stability of electrode materials.Finally,the further development direction of HCDI is proposed and suggested.
