Artificial Interfacial Layer Strategy for High‐Performance Zinc Metal Anodes: Mechanism and Application

With the increasing global demand for clean energy, aqueous zinc‐ion batteries have emerged as a promising candidate for large‐scale energy storage owing to their high safety, low cost, and environmental friendliness. However, challenges associated with zinc metal anodes, such as dendrite formation, hydrogen evolution reactions, and corrosion, significantly hinder their cycling stability and commercial viability. This review systematically summarizes eight functional strategies involving artificial interfacial layers to address these issues. This review provides a systematic summary of eight functional strategies based on artificial interfacial layers designed to overcome these issues. By analyzing the mechanisms of various interfacial materials, it highlights their effectiveness in suppressing dendrite growth, mitigating side reactions, and enhancing cycling performance, and further offers perspectives and recommendations for the rational design of highly reversible zinc anodes.
