The growing demand for the renewable energy storage technologies stimulated the quest for efficient energy storage devices. In recent years, the rechargeable aqueous zinc-based battery technologies are emerging as a compelling alternative to the lithium-based batteries owing to safety, eco-friendliness, and cost-effectiveness. Among the zinc-based energy devices, rechargeable zinc-ion batteries (ZIBs) are drawing considerable attention. However, they are plagued with several issues, including cathode dissolution, dendrite formation, etc.. Despite several efforts in the recent past, ZIBs are still in their infant stages and have yet to reach the stage of large-scale production. Finding stable Zn intercalation cathode material with high operating voltage and long cycling stability as well as dendrite-free Zn anode is the main challenge in the development of efficient zinc-ion storage devices. This Review discusses the various strategies, in terms of the engineering of cathode, anode and electrolyte, adopted for improving the charge storage performance of ZIBs and highlights the recent ZIB technological innovations. A brief account on the history of zinc-based devices and various cathode materials tested for ZIB fabrication in the last five years are also included. The main focus of this Review is to provide a detailed account on the rational engineering of the electrodes, electrolytes, and separators for improving the charge storage performance with a future perspective to achieving high energy density and long cycling stability and large-scale production for practical application.
对可再生能源存储技术日益增长的需求刺激了人们对高效储能设备的探索。近年来，由于安全性、生态友好性和成本效益，可充电水系锌基电池技术正成为锂电池的一种有吸引力的替代品。在锌基能源设备中，可充电锌离子电池（ZIBs）受到了相当大的关注。然而，它们存在几个问题，包括阴极溶解、枝晶形成等。尽管近年来人们做出了诸多努力，但ZIBs仍处于起步阶段，尚未达到大规模生产的阶段。寻找具有高工作电压、长循环稳定性的稳定锌嵌入阴极材料以及无枝晶的锌阳极是开发高效锌离子存储设备的主要挑战。本综述讨论了在阴极、阳极和电解质工程方面为提高ZIBs的电荷存储性能而采用的各种策略，并突出了最近的ZIB技术创新。还简要介绍了锌基设备的历史以及过去五年中用于制造ZIBs的各种阴极材料。本综述的主要重点是从实现高能量密度、长循环稳定性和大规模实际应用的未来角度，详细阐述电极、电解质和隔膜的合理设计，以提高电荷存储性能。
