Summary: Chronopotentiometry using constant current pulses is a powerful method for characterizing ion-exchange membranes, allowing for the quantification of coion transport based on ChP analysis. Coion transport can influence the shape of the chronopotentiogram, with potential peaks observed at overlimiting current densities due to increased coion transfer. Mathematical modeling based on Nernst-Planck-Poisson equations shows that the cause of these peaks is current-induced concentration polarization leading to increased coion transfer.

Summary: This study investigates the effects of non-conductive pattern structures on ion transport through ion exchange membranes in electrodialysis (ED). The study identifies two factors, electric view factor and vortex intensity, that control conductive/convective ion transports. Experimental results on a two-dimensional ED platform show that these factors play a significant role in determining current, ion conduction, and salt removal performance.

Summary: The creation of monovalent selective ion exchange membranes helps in desalinating surface waters by removing interfering monovalent ions while preserving polyvalent ionic nutrients. Studies have shown that the number of formed layers and the nature of the external layer have a significant effect on the properties of the resulting membranes. Changes in properties, such as the dependence of limiting current densities, enhanced electroconvection, and decreasing monovalent selectivity, occur with increasing numbers of layers in the layer-by-layer coated heterogeneous membranes.

Summary: This study experimentally demonstrates the mass transport effects of partially masked ion-exchange membranes in microfluidic electrodialysis systems. Different masking membranes were prepared by depositing non-conductive films on parts of the membranes. The results show that overlapped masking membranes exhibit better electrical conductance and current/energy efficiency, while a reduction in the unit length of unmasked ion-exchange membranes enhances overall mass transport.

Summary: Electroconvection and gravitational convection are identified as the main mechanisms influencing overlimiting currents in ion-exchange systems. Particle image velocimetry (PIV) is used to analyze convection on a heterogeneous cation-exchange membrane, revealing characteristics in both horizontal and vertical planes. The study demonstrates the presence of chaotic vortices, counter-current vortices, and the dominance of gravitational convection in generating upward-directed flow compared to electroconvection. The development of gravitational convection is slower than that of electroconvection.

Summary: This study investigates the induction of overlimiting current in high voltage applications through the development of an electroconvective vortex. The dynamics of the vortex are controlled using a one-dimensional grid-patterned ion exchange membrane (IEM). The research shows that the electric potential fall rate increases rapidly during vortex development and decreases gradually during vortex merging. The study also demonstrates the successful performance of the 1D grid-patterned IEMs in terms of overlimiting currents and desalination.

Summary: This paper simulates the changes in structure and transport properties of an anion-exchange membrane (CJMA-7) caused by modification with a perfluorosulfonated ionomer (PFSI). The results show that the PFSI film formed on the membrane does not significantly affect its properties, but mainly blocks the transport of coions by clogging the macropores. The modified membrane shows a decreased transport number for coions.

Summary: This study investigates the mechanism of permselectivity in ion-exchange membranes using a 1D model based on the Nernst-Planck-Poisson equation system. The results show that the change in permselectivity coefficient with increasing current density is mainly due to the change in the membrane/solution layer. At low current densities, divalent ions control the ion fluxes, while at higher current densities, monovalent ions become predominant. The study provides insights into the trade-off between membrane permselectivity and permeability.

Summary: This paper investigates the influence of membrane/electrode surface heterogeneity on the electrochemical behavior of membrane/electrode systems under current-induced concentration polarization. The low-frequency electrochemical impedance spectra of electrically heterogeneous ion-exchange membranes (IEMs) are studied both experimentally and theoretically. A 2D model is proposed to calculate these spectra, and the non-stationary ion transport through a heterogeneous membrane and two adjacent diffusion layers is analyzed. The impedance spectrum of a heterogeneous IEM is shown to exhibit a finite-length-Warburg-type impedance at low frequencies, and a nose-shaped element at relatively high frequencies, reflecting an increase in system resistance due to higher concentration polarization.

Summary: In recent years, commercially available innovative ion exchange membranes have been introduced. However, there is a lack of comprehensive information regarding their structure and transport characteristics. This study investigates homogeneous anion exchange membranes (ASE, CJMA-3, CJMA-6) in various solutions to understand their properties. Results show that ASE has a highly cross-linked aromatic matrix and contains quaternary ammonium groups, while CJMA-3 and CJMA-6 have less cross-linked aliphatic matrices based on polyvinylidene fluoride and polyolefin, respectively. In NaCl solutions, the conductivity of the membranes is found to increase with ion-exchange capacity, with CJMA-6 showing the highest conductivity. Additionally, weakly basic amines in CJMA-6 form bound species with proton-containing phosphoric acid anions, leading to decreased electrical conductivity in phosphate-containing solutions.

Summary: New processes are needed for recycling valuable materials from used lithium-ion batteries (LIBs) in order to meet growing global demand and address the electronic waste crisis. This study demonstrates the use of a hybrid electrobaromembrane (EBM) method for selectively separating Li+ and Co2+ ions. The results show that ion separation efficiency for a lithium/cobalt pair can be very high using this method, and the presence of coexisting nickel ions does not affect the separation of lithium.

Summary: Phosphate recovery through electrodialysis (ED) is a promising method for a nutrients circular economy, but the low ED performance and formation of bonded species between phosphates and weakly basic fixed groups hinder its widespread adoption. The use of intense current modes in ED processing and shielding the fixed groups with a modifier containing quaternary ammonium bases significantly improve the ED performance for phosphate recovery. Studies using the commercial anion exchange membrane CJMA-2 showed enhanced performance in terms of faster phosphate recovery and reduced energy consumption.
