The modern technical era demands sustainable and green energy production and storage methods that overcome the limitations of conventional fuel resources. Electrochemical energy storage (ECS) technologies are widely anticipated to store and release energy on repeated cycles for domestic and commercial utilization. Several ECS devices were developed over the years to achieve higher energy density and energy sustainability. Zn-air batteries are developed to deliver higher energy density and their lower maintenance, flexibility, and rechargeability made them the significant sustainable energy device. However, the Zn anodes face several issues due to dendrite formation during several discharge cycles, HER at higher negative potentials, and corrosion behavior. Therefore, Zn-anode design strategies and significant electrolyte modifications were adopted to limit the critical issues. The review promptly exhibits the significance of Zn-air battery and their construction strategies. The present review highlights the rational design strategies for the stabilization of the Zn anode, such as coating with a passive layer, heterostructure and alloy-composite formation, and the major electrolyte modifications, such as using organic electrolytes, additives in aqueous electrolytes, and solid-state polymer gel electrolytes. The review is expected to attract a wide range of readers, from beginners to industrialists, which serve as a guide for developing Zn-air batteries.
现代技术时代需要可持续和绿色的能源生产及存储方法，以克服传统燃料资源的局限性。电化学储能（ECS）技术被广泛期待能够在重复循环中存储和释放能量，以供家庭和商业使用。多年来，人们开发了几种ECS装置，以实现更高的能量密度和能源可持续性。锌空气电池的开发旨在提供更高的能量密度，其较低的维护成本、灵活性和可充电性使其成为重要的可持续能源装置。然而，锌阳极在几个放电循环中会因枝晶形成、在较高负电位下的析氢反应（HER）以及腐蚀行为而面临几个问题。因此，人们采用了锌阳极设计策略和重要的电解质改性方法来限制这些关键问题。该综述迅速展示了锌空气电池的重要性及其构建策略。本综述重点介绍了稳定锌阳极的合理设计策略，如涂覆钝化层、形成异质结构和合金复合材料，以及主要的电解质改性方法，如使用有机电解质、在水性电解质中添加添加剂和固态聚合物凝胶电解质。预计该综述将吸引从初学者到实业家的广泛读者群体，为锌空气电池的开发提供指导。
