Abstract
Anion exchange membranes (AEMs) enable the selective transport of anions, playing a crucial role in renewable electrochemical energy conversion technologies. Recent decades have witnessed significant breakthroughs in AEM design strategies, synthesis methodologies, and performance optimization. Unfortunately, moving from fundamental research to commercialization remains a huge challenge despite the great market demand for AEM. In this review, we first discuss the current technological requirements and analyze the state of AEM. Then, we focus on the bottlenecks encountered and solved in scaling up chemical reactions and implementing roll-to-roll (R2R) manufacturing processes. Finally, we prospect the future development of commercial AEM from the monomer structure-membrane stability relationships, mechanism understanding in amplification polymerization, and environment and cost-effectiveness assessments. This comprehensive analysis aims to bridge the gap between fundamental research and the commercialization of AEM and to accelerate the deployment of AEM in relevant technologies.
