Among energy storage technologies available or currently being developed, one of the most promising and attractive electrochemical system is the vanadium redox flow battery (VRFB). One of the key components in VRFB is the membrane required to separate the positive and negative half-cells. The role of this membrane is to prevent cross-mixing of vanadium ions while allowing the transport of certain ions to maintain the electrolytes’ electro-neutrality. Such a membrane represents a sizeable fraction of the system’s total cost while significantly affecting performance. Current research mostly consists of developing high-performance membranes offering high ionic conductivity, low permeability to vanadium ions, and good chemical and mechanical stability. A lower membrane cost is also desirable in order to reduce the overall system costs. This paper provides a comprehensive review of VRFB membranes and recent developments to allow for a better understanding of VRFB membranes’ characterization techniques and their different manufacturing methods, while exploring materials suitable as VRFB membrane. Modeling of ion transport mechanisms through the separator and development prospects for a high-performance VRFB membrane are also discussed. The characteristics of the newly developed membranes are summarized to serve as a reference guide for researchers.

“…34 According to the Grotthuss mechanism, sulfonic groups aid the transportation of ions in water. 1,35 The sulfonation of 2,3-dialdehyde cellulose with bisulfite is an attractive synthesis route, as it can be conducted in an efficient manner under mild aqueous reaction conditions and without the use of harmful solvents. 14,19,36,37 The results revealed that NaIO 4 treatment for 24 h resulted in increased BC sulfonation than treatment for 48 h (Figure 7).…”

In this study, we investigated the effects of the modification of bacterial cellulose used as a template on the in situ polymerization of catechol by laccase. The bacterial cellulose was modified by sulfonation and the entrapment of carboxymethyl cellulose. The catechol polymerization was optimized at a pH of 5.5, catechol concentration of 50 mM, and synthesis time of 24 h. After the in situ polymerization, conductive and colored bacterial cellulose composites were obtained. The bacterial cellulose composites containing oligomers/polymers were analyzed using Fourier-transform infrared spectroscopy, scanning electron microscopy, and color strength measurements, and the conductivity of the bacterial cellulose composites was evaluated using a four-probe method. The results revealed that the modification of bacterial cellulose as a template for catechol oxidation resulted in the production of fibers with enhanced coloration and conductive properties owing to the presence of the enzymatically-obtained polymers. The results suggest the promising potential of both sulfonated bacterial cellulose and carboxymethyl cellulose-bacterial cellulose as templates for the formation of other functional polymers and composite materials.

“…Amphoteric membranes, which have both cations and anions covalently bonded to their structures, have been synthesized and characterized to maintain good conductivity while lowering vanadium permeability. [30][31][32][33][34][35][36][37][38][39][40][41][42][43] Studies have characterized the permeability of vanadium ions across the membrane, but such studies often do not consider the migrative flux of vanadium that may dominate in working VRFBs. Equation 6shows a non-dimensional parameter, M D, that may be helpful to quantify the significance of migration in VRFBs.…”

The performance of vanadium redox flow batteries (VRFBs) is impacted by the diffusion and migration of the vanadium species across the separator. In this work, the vanadium crossover as a function of current density for vanadium-containing electrolytes of various state of charge (SOC) and state of discharge (SOD) is measured. Experiments conducted with electrolytes at complete charge/discharge yielded direct measurements of the transference numbers of the vanadium species. The transference numbers of V2+, V3+, VO2+, and VO2 + were estimated to be 0.064 ± 0.002, 0.087 ± 0.003, 0.068 ± 0.003, and 0.018 ± 0.002, respectively. Experiments conducted with electrolytes at intermediate states of charge/discharge yielded direct measurements of the sum of transport numbers of the vanadium species. The transport number estimates are quantitatively related to faradaic efficiency loss and capacity fade of a working VRFB.
