“…In order to make further efforts to investigate the capacity retention property and the self-discharge degree of ICRFB single-cell assembled with various Nafion membranes with different thickness, the OCV curve was specially recorded to understand the self-discharge trend. 40,41 For all the three single cells, the OCV gently declines at first and then suddenly drops to 0.2 V. For N117, N115, and N212 membranes to reach 0.2 V, the self-discharge time is 108, 87, and 50 hours, respectively. As shown in Figure 2, the starting OCV value of the ICRFBs drops gradually with time, and the slope of OCV reduction is larger with the lessening of the membrane thickness.…”

Summary To boost the performance of the iron‐chromium redox flow battery (ICRFB), opting an appropriate proton exchange membrane (PEM) as the core component of ICRFB is of great importance. For the purpose, in this paper, various widely adopted commercial Nafion membranes with a different thickness of 50 μm (Nafion 212, N212), 126 μm (N115), and 178 μm (N117) are chosen for the sake of evaluating the influence of membrane thickness on the ICRFB single‐cell performance. Physicochemical properties, electrolyte utilization, cell efficiency, long‐term cycling stability, and the self‐discharge process of ICRFBs based on a series of Nafion membranes are contrasted comprehensively. The cycling test of ICRFBs is carried out under the current density range of 40 to 120 mA/cm2 for the charge‐discharge process. As a result of the good equilibrium of membrane resistance and electro‐active species permeability, Nafion 212 membrane exhibits the highest electrolyte utilization and energy efficiency during the operation, accompanied by the lowest overpotential. In the final part, the selection of Nafion membrane thickness was optimized on the basis of single‐cell performance and the overall cost of the system.

“…Both Nafion TM 112 and Nafion TM 1135 exhibit serious VO 2+ permeability, so they can't be applied in VRB. In addition, Nafion TM 117 membrane shows the highest capacity retention and relatively high EE among all of Nafion TM membranes at 120 mA cm À2 [24]. Therefore, like majorities of literatures [25][26][27][28], Nafion TM 117 membrane was chosen as a representative for comparison in this work.…”

Novel polysulfone membranes with bunch-like tertiary amine groups are synthesized with high ion selectivity and outstanding chemical stability for vanadium redox flow batteries (VRFBs). The bunch-like tertiary amine groups simultaneously act as an ionic conductor for proton hopping and vanadium ion transport obstacles. The performance of the membrane is tuned via controlling the grafting degree of the chloromethylated polysulfone. The results show that membranes show increasing proton over vanadium ion (σ/p) selectivity with increasing functional tertiary groups. VRFBs assembled with the prepared membranes demonstrate an impressive Coulombic efficiency of 98.9% and energy efficiency of 90.9% at a current density of 50 mA cm . Furthermore, the prepared membrane reported in this work shows excellent stability in 1 m VO solution at 35 °C over 240 h. Overall, the synthesized polymers provide a new insight into the design of high-performance membranes toward VRFB applications.
