Abstract:

Capacitive deionization (CDI) technology,with low cost,low energy consumption and high efficiency,is an effective method to alleviate the water crisis. Flow-electrode capacitive deionization(FCDI) technology coupled with the flowable electrode and ion exchange membrane can effectively address the technical bottleneck of traditional CDI technology,including limited adsorption capacity and discontinuous operation. Over the past ten years,FCDI technology has been actively explored in terms of theoretical research,material development and engineering application,and has shown excellent application potential. Herein,this paper systematically reviewed the research progress of FCDI technology. The development history and its involved mechanism was firstly introduced. Then,the optimization method of FCDI system was analyzed in depth from several key factors,including device configuration,operation mode,material innovation and parameter influence. Furthermore,special attention has been paid to the representative applications in different fields,and the economy and practicability was evaluated. Finally,a conclusion of the review and subsequently,perspectives are given for possible research directions.

Key words: flow-electrode capacitive deionization, system optimization, desalination, resource utilization
