Modular Interfacial Engineering via Nanofiber‐Reinforced Hydrogels for Stabilizing Zn Anodes Toward High‐Performance Zn‐Based Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Inspired by reinforced concrete casting, a modular interfacial engineering strategy was developed by integrating a rigid polyacrylonitrile fiber skeleton with an ion‐regulating hydrogel matrix. This composite interface homogenizes Zn2+ flux, accelerates ion transport, and stabilizes Zn deposition while suppressing hydrogen evolution and corrosion ...
