An Adaptive Ionic Sieve: Flexible Hydrogen‐Bonded Organic Frameworks Decouple the Trade‐Off Between Zn Ions Desolvation and Mass Transfer

Honghui Bi, Zongbin Zhao, Qi Yang, Bolun Zhang et autres

ABSTRACT Efficient ion desolvation and rapid mass transport are crucial yet often competing requirements for stabilizing Zn anodes in aqueous Zn‐ion batteries. This dilemma arises because ion desolvation introduces additional energy barriers that increase ion diffusion resistance. To reconcile this inherent trade‐off, …
