“…Layer-by-layer (LbL) self-assembly is another widely used method to prepared AIEMs,b ut it is usually applied to modifying the surface of af oregone membrane such as Nafion. [56] Recently,a ni nteresting work reported that welloriented proton-conductive nanochannels could be induced in SPEEK membranes based on 3-(1-hydroimidazolium-3-yl)propane-1-sulfonate additive via acid-base interactions, boosting ah ighly conductive IEM for VRFBs. [57] Polymer blends other than AIEMs have also been reported in recent years for RFBs,s uch as PBI/AEM, CEM/lignin, and cellulose-nanocrystals/PVDF-HFP.…”

Redox flow batteries (RFBs) are among the most promising grid‐scale energy storage technologies. However, the development of RFBs with high round‐trip efficiency, high rate capability, and long cycle life for practical applications is highly restricted by the lack of appropriate ion‐conducting membranes. Promising RFB membranes should separate positive and negative species completely and conduct balancing ions smoothly. Specific systems must meet additional requirements, such as high chemical stability in corrosive electrolytes, good resistance to organic solvents in nonaqueous systems, and excellent mechanical strength and flexibility. These rigorous requirements put high demands on the membrane design, essentially the chemistry and microstructure associated with ion transport channels. In this Review, we summarize the design rationale of recently reported RFB membranes at the molecular level, with an emphasis on new chemistry, novel microstructures, and innovative fabrication strategies. Future challenges and potential research opportunities within this field are also discussed.

“…The all vanadium redox flow battery (all-V RFB) is the most prospective RFB energy storage system [1]. The key materials of an all-V RFB comprised of a separation membrane, an electrode, an electrolyte, and a flow channel [2][3][4][5][6][7] these which can induce a different thermal effect. The key factors, which affect the temperature evolution of an all-V RFB during the charge-discharge operations, include the reversible and irreversible enthalpy and entropy change of the electrochemical reactions, and the self-discharge circumstances due to the ion cross-contamination [8][9][10].…”

“…In thermoelectrochemical models, the (∆S o r ) of the cell can be calculated, which quantity represents the heat output or consumption of the cell. The ∆S o r is proportional to the (∂E o r /∂T) (also called the "temperature coefficient"), which is the partial derivative of the cell potential with temperature, as shown in Equation (3) [19,20].…”

In this study, a new monitoring method was developed, titled infrared thermal imaging technology, which can effectively evaluate the thermal effect of the charge-discharge test in the vanadium/iodine redox flow battery (V/I RFB). The results show that the all-vanadium redox flow battery (all-V RFB) has a greater molar reaction Gibbs free energy change than that of the V/I RFB, representing a large thermal effect of the all-V RFB than the V/I RFB. The charge-discharge parameters, flow rate and current density, are important factors for inducing the thermal effect, because of the concentration polarization and the ohmic resistor. The new membrane (HS-SO3H) shows a high ion exchange capacity and a good ions crossover inhibitory for the V/I RFB system, and has a high coulomb efficiency that reaches 96%. The voltage efficiency was enhanced from 61% to 86% using the C-TiO2-Pd composite electrode as a cathode with the serpentine-type flow field for the V/I RFB. By adopting the high-resolution images of an infrared thermal imaging technology with the function of the temperature profile data, it is useful to evaluate the key components’ performance of the V/I RFB, and is a favorable candidate in the developing of the redox flow battery system.
