Abstract
Abstract Aqueous zinc metal batteries have attracted much attention in the field of large‐scale energy storage due to their abundant resources, high safety, low cost, and high theoretical energy density. However, Zn anodes suffer from serious problems such as dendrite growth, hydrogen evolution reaction, corrosion, and passivation. Cu‐based materials have a wide range of applications in Zn anodes due to their excellent zincophilicity. Unfortunately, relevant review on Cu‐based materials in anode electrode is still lacking. This review focuses on the progress, issues, and optimization strategies of Cu‐based materials in Zn anodes. The application of Cu collectors in Zn anodes and the corresponding modifications are also highlighted. Finally, insights and future directions related to Cu‐based materials for modified Zn anode and Cu collectors are presented to provide scientific guidance for future research.
