Abstract Low-electrode capacitive deionization (FCDI) is an emerging desalination technology with great potential for removal and/or recycling ions from a range of waters. However, it still suffers inefficient charge transfer and ion transport kinetics due to weak turbulence low electric intensity in flow electrodes, both restricted by the current collectors. Herein, new tip-array collector (designated as T-CC) was developed replace conventional planar collectors, which intensifies significantly. The effects tip arrays on fields were studied computational simulations electrochemical impedance spectroscopy, revealed reduction barrier, barrier internal resistance. With voltage increased 1.0 1.5 2.0 V, T-CC-based FCDI system (T-FCDI) exhibited average salt rates (ASRR) 0.18, 0.50, 0.89 μmol cm −2 min −1 , respectively, are 1.82, 2.65, 2.48 folds higher than that serpentine 1.48, 1.67, 1.49 Meanwhile, solid content electrodes 1 5 wt%, ASRR T-FCDI 0.29 0.50 1.70 1.67 Additionally, efficiency 99.89% achieved remained above 95% after 24 h operation, thus showing its superior long-term stability.

Flow-electrode Capacitive Deionization (FCDI) is a relatively young technology that allows energy-efficient desalination and salt concentration. FCDI employs flow electrodes, suspensions of conductive particles capable storing ions in the electric double layer at their surface upon charging. To facilitate charging, electrode must be electrically contacted using current collectors. Current collectors guide along membrane surface, provide area for electrical contact with particles, inert high concentrations. In this study, we compare different collector architectures FCDI. Graphite plates membrane-electrode assemblies made carbon fiber fabric are two described recent literature. We introduce new architecture based on bipolar plate expanded graphite. These novel show up to 55 % higher transfer than graphite plates, rendering them valuable modules. Comparative analysis shows side walls channel more effective charge transport bottom wall. Furthermore, roughness impacts transport, smoother surfaces leading removal rates.
