“…This kind of polymers can be subdivided into: aliphatic copolymers synthesized by free radical polymerization 133–140, plasma‐polymerization 141–144, ring‐opening polymerization 145, 146, ATRP 147 and RAFT 148, random aromatic copolymers 149–175, copolymers with locally high concentration of ammonium moieties 176–184, and multi‐block copolymers 185–190, especially with long hydrophilic/hydrophobic blocks 191–197.…”

This review focuses on various synthesis strategies of anion‐exchange membranes (AEMs) for fuel cells, diverse methodologies of AEM‐forming, together with relationship between structures and properties. AEMs are discussed from seven categories, including (1) AEMs derived from Nafion precursors with sulfonyl fluoride groups, which display excellent stability and well‐developed morphologies that similar to Nafion, but has potentially high costs. (2) AEMs prepared by grafting technologies, such as chemical grafting technique, ATRP technique, plasma grafting technique and radiation grafting technique. (3) AEMs based on functionalized commercial polymers, including PVA, SEBS, CPP, PEEK, PES, PEI, PPO, and so on. (4) AEMs prepared by newly‐synthesized polymers, in which the most interesting approach is to synthesize alkaline multi‐block copolymers with enough long hydrophilic/hydrophobic blocks. (5) AEMs containing heterogeneous composition, which mainly prepared by blending and sol‐gel methods, reinforced or pore‐filling AEMs and IPN or s‐IPN. (6) AEMs with functional groups different from quaternary ammonium, which includes the studies of new type of AEMs with highly chemical stability in alkaline solution. (7) Hybrid membranes combining AEM with PEM, in which new configuration results in different performances. At last, conclusions and perspectives for the future researches of AEMs are presented.

“…Table 1 shows the recently developed AEMs and their performance under several experimental conditions such as temperature, RH, and flow rate. dimensional and chemical stability [7,124,125]. In addition, OHconductivity of AEM is highly dependent on water, for instance, the state of art on FAA-3 membrane shows more than ten times increment in through-plane ionic conductivity when measured at 90% RH compared to 50% RH as shown in Figure 5 [128].…”

In spite of significant achievements in alkaline exchange membrane fuel cells (AEMFCs) in recent years, they are still lagging behind proton exchange membrane fuel cells (PEMFCs) due to performance instability. Among the relevant operational parameters of AEMFC, the researchers have found that poor water management within the cell was the main reason for failure of the system. In the past five years, numerous modeling and experimental works were reported proposing different strategies to improve water management of AEMFC. The achievable power output in AEMFCs is then comparable with that of PEMFCs or even more. Efforts have to be continued, but AEMFCs can become a strong competitor in the market place. This review paper discusses the strategies and developments impacting water management of AEMFCs providing knowledge source for upcoming studies.

“…As discussed in Section 2, various cation group types, including QA [78][79][80], imidazolium [81,82], phosphonium [83,84], and guanidinium [85,86] have been used for preparing AEMs. Among them, QAs are the most frequently used because they are not only easy to prepare, but also easier to attach to the polymer backbone.…”

Prospects for Anion-Exchange Membranes in Alkali Metal–Air Batteries

Rechargeable alkali metal–air batteries have enormous potential in energy storage applications due to their high energy densities, low cost, and environmental friendliness. Membrane separators determine the performance and economic viability of these batteries. Usually, porous membrane separators taken from lithium-based batteries are used. Moreover, composite and cation-exchange membranes have been tested. However, crossover of unwanted species (such as zincate ions in zinc–air flow batteries) and/or low hydroxide ions conductivity are major issues to be overcome. On the other hand, state-of-art anion-exchange membranes (AEMs) have been applied to meet the current challenges with regard to rechargeable zinc–air batteries, which have received the most attention among alkali metal–air batteries. The recent advances and remaining challenges of AEMs for these batteries are critically discussed in this review. Correlation between the properties of the AEMs and performance and cyclability of the batteries is discussed. Finally, strategies for overcoming the remaining challenges and future outlooks on the topic are briefly provided. We believe this paper will play a significant role in promoting R&D on developing suitable AEMs with potential applications in alkali metal–air flow batteries.
