Abstract
Abstract Aqueous Zn metal batteries have attracted much attention due to their high intrinsic capacity, high safety, and low cost. Nevertheless, uncontrollable dendrite growth and adverse side reactions of Zn anodes seriously hinder their further application. Herein, a three‐dimensional (3D) porous graphene‐carbon nanotubes scaffold decorated with metal–organic framework derived ZnO/C nanoparticles (3D‐ZGC) is fabricated as the host for dendrite‐free Zn‐metal composite anodes. The zincophilic ZnO/C nanoparticles act as preferred deposition sites with low nucleation barriers to induce homogeneous Zn deposition. The mechanically robust 3D scaffold with high conductivity not only suppresses the formation of…
