Engineers in Prof. Vijay Ramani’s laboratory have developed a variety of robust, versatile anion exchange membrane (AEM) materials that achieve high performance through superior ion selectivity. These mechanically and chemically stable membranes have the potential to d…
— Background: Anion exchange membranes (AEMs) are used as separators in redox flow batteries, water electrolyzers, water desalination systems, fuel cells, and other electrochemical devices. Current AEMs suffer from issues with cost, poor stability and low perm selectivity. For example, current redox flow batteries are not economical or suffer from capacity loss upon cycling due to cross species contamination while using less expensive decoupled chemistries.
