A Selectively Permeable Membrane for Enhancing Cyclability of Organic Sodium‐Ion Batteries

Abstract

A novel strategy to enhance the cyclability of organic sodium-ion batteries is developed by applying a selectively permeable membrane to allow the passage of Na ions but block the slightly dissolved active molecules and thereby inhibit the further dissolution. After utilization of the membrane, the batteries show highly enhanced cyclability. Such strategy can be potentially extended to many organic materials with low solubilities.
