“…Compared with Nafion 117, at a DOG of about 40 %, the resulting AIEM exhibits similar ionic conductivity (54 vs. 58 mS cm -1 ), higher IEC (1.2 vs. 0.97 mmol g -1 ) and lower vanadium ion permeability (0.69 × 10 -7 vs. 7.89 × 10 -7 cm 2 min -1 ). Moreover, it exhibits much better chemical stability than the AIEM grafted with St and DMAEMA, and the OCV of VRB with this AIEM shows better performance than that with Nafion 117 (60 h vs. 14 h, OCV > 1.4 V, 41.1 % DOG) [71].…”

In recent years, much attention has been paid to vanadium redox flow batteries (VRBs) because of their excellent performance as a new and efficient energy storage system, especially for large-scale energy storage. As one core component of a VRB, ion exchange membrane prevents cross-over of positive and negative electrolytes, while it enables the transportation of charge-balancing ions such as H + , 2 4 SO , − and 4 HSO − to complete the current circuit. To a large extent, its structure and property affect the performance of VRBs. This review focuses on the latest work on the ion exchange membranes for VRBs such as perfluorinated, partially fluorinated, and nonfluorinated membranes. The prospective for future development on membranes for VRBs is also proposed.

“…The PVDF-g-PMAODEMACco-PAMSSA membranes possess relatively lower permeability of vanadium ions, higher IEC and similar conductivity compared to Nafion ® 117. Moreover, the membrane tested in VRFB has higher open circuit voltage than that of Nafion ® 117 [239].…”

“…Another AIEM for VRFB was synthesized by radiation-induced grafting of AMS and DMAEMA and subsequent sulfonation and protonation [239]. The PVDF-g-PMAODEMACco-PAMSSA membranes possess relatively lower permeability of vanadium ions, higher IEC and similar conductivity compared to Nafion ® 117.…”

“…[52,53] However,membranes from aromatic,n onfluorinated polymers frequently do not have as ufficient chemical stability to vanadium electrolyte solutions [54,55] and tend to form cracks. [58][59][60][61][62] c) Amphoteric ion-exchange membranes have both cationic and anionic groups.T hese membranes are generally obtained by the radiation-graft copolymerization of prefabricated films or powdered PVDF [63][64][65][66] or ETFE [67] with the help of gamma rays.C ationic groups are inserted using grafted polystyrene or a-methylstyrene and subsequently sulfonated with chlorosulfuric acid. Base polymers include poly-(vinylbenzylstyrene) copolymer cross-linked with adipic acid, [56] poly(fluorenyl ether), [57] or poly(aryl ether ketone phtalazinone) (PAEKP).…”
