Fixed‐Linkage Enabled Ultra‐Stable Ion Transport Channels in Membranes for Long‐Life Alkaline Flow Batteries

Advanced Science, EarlyView.
Rigid fixed‐ethylene‐linked PBI membrane stabilizes ion‐transport channels, enabling high ionic conductivity and durable alkaline Zn─Fe flow batteries. ABSTRACT Alkaline zinc–iron redox flow batteries (Zn─Fe FBs) are promising candidates for developing high‐voltage and cost‐effective grid‐scale energy storage systems.

Decoding Structure‐Property Relationships in Anion Exchange Membranes via a Chemically Informed Dual‐Channel Graph Attention Network

Advanced Science, EarlyView.
SPARK decodes structure‐property relationships in anion exchange membranes (AEMs) via a chemically informed dual‐channel graph attention network (DEGAT) that explicitly captures microphase separation. It outputs five‐level grades for hydroxide conductivity and alkaline stability and highlights relevant key structural units, enabling robust pre ...
