Anion-exchange membranes (AEMs) have attracted tremendous research interest in alkaline energy devices such as AEM fuel cells (AEMFCs), AEM water electrolyzers (AEMWEs), CO2 reduction reaction (CO2RR), and redox flow batteries due to the feasible utilization of earth-abundant non-noble catalysts. AEM-based energy devices are intended to supersede costly acidic energy systems and provide a low-cost pathway for sustainable energy conversion and utilization. Specifically, AEMs and ionomers are crucial components for alkaline energy devices to conduct anions (typically OH−) and separate fuels between the anode and cathode. Highly ion-conductive, and durable AEMs are an interesting topic in alkaline energy devices. Currently, the ion conductivity and durability of AEMs have been substantially improved in the past few years due to the discovery of efficient aryl ether-free polymers and stable cationic groups, resulting in significant progress in several energy devices. Here, the advances in AEMs and AEM-based energy devices will be presented by understanding their structure-function relationship, covering durable and promising cationic groups, polymer backbones, and AEMs for fuel cell and water electrolysis. This will highlight the importance of AEMs and guide future research.
