T-017637

— 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.An advanced, tunable AEM has been developed with dramatically reduced cost and improved performance relative to industry leading AEMs. High ionic conductivity, chemical stability and enhanced mechanical performance have been shown. The technology includes tunable membrane compositions, mechanical re…
