Researchers at the University of Chicago and New York University have challenged the traditional belief that excess free water is necessary for fast ion transport in anion exchange membranes (AEMs). The study reveals that maintaining a well-connected network of water molecules within the membrane is key to efficient ion movement, rather than relying on high levels of free-flowing water. By combining simulations and experimental data, the researchers demonstrated that structured water networks and water shells surrounding ions enable faster ion transport without compromising membrane stability. This breakthrough offers a new approach to optimizing energy membranes for applications like fuel cells and redox flow batteries. The use of advanced techniques like 2D IR spectroscopy provided insights into the molecular-level dynamics of water within AEMs. The findings pave the way for designing next-generation materials that work efficiently even in low-humidity environments, making clean energy technologies more practical and durable. The research not only enhances our understanding of ion transport but also provides a framework for addressing other scientific challenges related to molecular movement.
