Frontispiece: A Sustainable and Scalable Approach for In Situ Induction of Gradient Nucleation Sites in Biomass-Derived Interface Layers for Ultra-Stable Aqueous Zinc Metal Batteries

Abstract

A biomass-based Cu²⁺-carboxymethyl chitosan-Kaolin (CuCK) layer composed of in-situ galvanically and galvanostatically induced gradient alloy sites is designed to achieve a durable Zn@CuCK anode, promoting continuous vertical zinc deposition, facilitating Zn²⁺ desolvation, and regulating Zn²⁺ flux. This study provides a sustainable and scalable method to in-situ induce gradient nucleation sites in durable Zn anodes for practical aqueous zinc metal batteries, as reported by Li-Feng Chen in their Research Article (e202504613).
