“…The performance of CDI is strongly affected by the electrode materials. Activated carbon (AC) , , carbon nanotubes (CNTs) , ordered mesoporous carbon , carbon aerogels , , carbon nanofibers , and graphene are widely used in CDI systems due to their high specific surface area, suitable pore structure, and good chemical stability. Traditional CDI with single carbon material as electrodes shows poor adsorption selectivity for ions, because these materials have no or weak ion selectivity , .…”

Activated carbon (AC) and carbon nanotubes (CNTs) were used to fabricate resin/carbon composite electrodes (D314/AC and D314/CNTs). The adsorption characteristics of vanadium (V) on the two electrodes under different pH and voltage conditions were compared in capacitive deionization. Physical and electrochemical studies on the electrodes indicated that micropores and mesopores are well balanced in D314/AC, but mesopores are dominant in D314/CNTs. D314/ CNTs showed higher specific capacitance and higher ion adsorption capacity than D314/AC. This study indicated that the adsorption performance of composite electrodes for V is affected by the electrode material, especially the pore properties.

“…Recent advances in CDI electrode materials have been focus on development of carbon materials with novel nanostructures. Nanostructured carbon materials such as carbon aerogels (CAs), [13][14][15] activated carbon (AC), [16][17][18] carbon nanotubes (CNTs), [19][20][21] carbon nano-bers (CNFs), [22][23][24][25] mesoporous carbon (MC), [26][27][28][29] carbon sphere 30 and graphene [31][32][33][34][35] have been reported to be widely studied and explored in CDI. However, these single component carbon materials suffer problems such as low electrosorption capacity, poor wettability or poor mechanical stability, which does harm their practical applications in CDI.…”

“…The wide pore distribution of AC may cause a severe reduction in capacitance over a short current drain time. 39,40 Several AC-based composites including: reduced graphene with AC (RG-AC), AC with metal oxides (AC-MO), AC with carbon nanotubes (AC-CNTS), AC with metal-organic frameworks (AC-MOFs), mesoporous carbon with carbon nanotubes (MC-CNTs), composite of mesoporous with microporous AC (CAs-AC) and AC with carbon nanofibers (AC-CNFs) 17,39,41 have been widely developed showing an improved interconnection structure in the matrix of the electrode. For example, Wouters et al employed metal oxides to modify carbon material for ion removal.…”

Design and optimization of electrode materials plays the pivotal role on the performance of capacitive deionization (CDI). Activated carbon (AC) has been a workhorse material for electrode fabrication in capacitive technologies. Several modification methods have been reported with enhanced activity and versatility attributes. Undeniably, tuning and tailoring AC properties have opened avenues for broadening the scope of applications, by meeting necessary features of electrodes for a given CDI cell configuration. This review traces the beneficial and also detrimental effects from various modifiers on AC electrodes with respect to CDI performance. Furthermore, a comprehensive classification of CDI cells based on different architectural aspects with a comparative performance is presented. On this basis, the tradeoff between physical, chemical, electrochemical properties in the course of electrode modification and the interdependence between electrode design and CDI cell configuration are discussed with disclosing some prospective guidelines on AC electrode design. It is important to evaluate the electrode materials and modifications in the way of practical including not only the electrode design, but also the cell architecture and operational parameters. This review aims to raise the attention on the rational electrode design by taking into account all necessary features of electrode in a given cell configuration.
