Janus‐Type Electrostatic Potential Gradient‐Activated Dynamic Zn 2+ ‐Coordinating Nitrogen Sites in Molecularly Locked Nanocellulose Separators for Stable Zinc‐Ion Batteries

cathode, the full pouch cell retains 85.8% of its capacity after 4000 cycles at ∼10 C. This work highlights that molecular functionalization of separators enables next-generation aqueous Zn batteries.
