“…Anfeng et al have recently exploited the excellent properties of SPEEK combined with organic components to develop hybrid membranes SPEEK/triphenylamine (TPAM), 110 SPEEK/polyimide (PI), 101 and SPEEK/ polyvinylpyrrolidon (PVP). 94 The novel hybrid membrane SPEEK/TPAM with various loadings of TPAM (1%, 2%, and 5%) exhibited lower vanadium permeability than SPEEK membranes due to the acid-base interaction between amine groups and sulfonated groups. 110 The introduction of triphenylamine also improved the conductivity of protons because the nitrogen atom of triphenylamine can be protonated and contribute to the transfer of protons.…”

“…SPEEK mixed with other polymers is an approach widely adopted in composite membranes production, enabling high proton conductivity on the one hand and good mechanical properties on the other hand. SPEEK has been blended with a variety of polymers such as polytetrafluorethylene (PTFE), 36,[89][90][91] poly(vinylidene fluoride) (PVDF), 10,26,39,46,92,93 polyvinylpyrrolidone (PVP), 94 tungstophosphoric acid (TPA), 95 polyphenylene oxide (PPO), 96,97 lignine, 98 polyacrylonitrile (PAN), 99 poly (ether imide) (PEI) 100 or polyimide (PI), 101 polybenzimidazole (PBI), 102 poly sulfone, 103 or poly(ether sulfone) (PES). 11,104,105 The performance of SPEEK membrane can be improved by modifying its microstructure with Nafion resin, 106 through a layer of Nafion combined with a layer of polypropylene (PP) 107 or by porogen DBP, as reported in Ref.…”

“…As for the SPEEK/PVP membrane, it prevents the passage of vanadium ions because of the network structure formed by the hydrogen bond between PVP and SPEEK. 94 Properties of this membrane were compared with those of pure SPEEK and Nafion 115 membranes. The study indicates that the CE and EE obtained by the battery with the hybrid membrane (SPEEK/ PVP) containing 30% PVP were 97.5% and 84.5%, respectively, at 60 mA cm À2 , with notable stability after 50 cycles.…”

Vanadium redox flow batteries (VRFB) are among the most promising approaches to efficiently store renewable energies. In such battery type, Nafion is commonly used as membrane material but suffers from high vanadium crossover and cost. These drawbacks negatively influence the widespread commercial application of VRFBs. Alternative membrane materials with high performance and low cost are thus being developed to address these shortfalls. Among those, possible materials for the VRFB membrane is sulfonated polyether ether ketone (SPEEK), which recently attracted considerable attention due to its low cost, combined with mechanical and chemical stability, and ease of preparation. This review summarizes the research activities related to the development of SPEEK-based membranes for VRFB applications and gives an overview of the properties of PEEK and its sulfonated form. A critical analysis on the challenges of SPEEK-based membranes is also discussed.

“…Since the acid‐base composite membrane can form a large amount of dense hydrogen bond networks between the acid‐base pairs, it plays an effective role in resisting the crossing of vanadium ions. Wang and co‐workers blended SPEEK with PVP to prepare an acid‐base composite membrane [20d] . The surface morphology of the membrane is uniform and compact (Figure 13d).…”

Polymer electrolyte membranes (PEMs) play vital roles in electrochemical energy conversion and storage devices, such as polymer electrolyte membrane fuel cell (PEMFC), redox flow battery, and water electrolysis. As the crucial component of these devices, PEMs need to possess high ion conductivity and electronic insulation, remarkable mechanical and chemical stability, and outstanding isolation function for the materials on both sides of the cathode and anode. Polyvinylpyrrolidone has received widespread attention in the research of PEMs owing to its tertiary amine basic groups and exceptional hydrophilic properties. This review focuses on the application status of polyvinylpyrrolidone-based PEMs in PEMFC, vanadium redox flow battery, and alkaline water electrolysis, and describes in detail the key scientific problems in these fields, providing constructive suggestions and guidance for the application of polyvinylpyrrolidone-based PEMs in electrochemical energy conversion and storage devices.

“…PVP is a commodity reagent, widely used as a hydrophilic polymer in the preparation and modification of filtration membranes [ 50 , 51 ] or as a precursor for ion exchange membrane fabrication. In recent works, membrane containing PVP were positively tested for application in VRFBs [ 52 , 53 ]. In highly acidic conditions the pyrrolidone segments can be protonated, facilitating ion conductivity and reducing vanadium permeation due to a positive charge [ 54 ].…”

Composite Anion Exchange Membranes Fabricated by Coating and UV Crosslinking of Low-Cost Precursors Tested in a Redox Flow Battery

et al. 2021

This paper presents a novel, cost-effective approach to the fabrication of composite anion exchange membranes (AEMs). Hierarchical AEMs have been fabricated by coating a porous substrate with an interpenetrating polymer network (IPN) layer where poly(vinylpyrrolidone) (PVP) is immobilized in a crosslinked matrix. The IPN matrix was formed by UV initiated radical crosslinking of a mixture of acrylamide-based monomers and acrylic resins. The fabricated membranes have been compared with a commercial material (Fumatech FAP 450) in terms of ionic transport properties and performance in a vanadium redox flow battery (VRFB). Measures of area-specific resistance (ASR) and vanadium permeability for the proposed membranes demonstrated properties approaching the commercial benchmark. These properties could be tuned by changing the content of PVP in the IPN coating. Higher PVP/matrix ratios facilitate a higher water uptake of the coating layer and thus lower ASR (as low as 0.58 Ω.cm2). On the contrary, lower PVP/matrix ratios allow to reduce the water uptake of the coating and hence decrease the vanadium permeability at the cost of a higher ASR (as high as 1.99 Ω.cm2). In VRFB testing the hierarchical membranes enabled to reach energy efficiency comparable with the commercial AEM (PVP_14—74.7%, FAP 450—72.7% at 80 mA.cm−2).
