Rechargeable zinc‐ion batteries (ZIBs) based on near‐neutral aqueous electrolytes have been actively researched in recent years as an alternative large‐scale stationary storage device because of their outstanding merits in energy density, safety, cost, and environmental impact. Although remarkable materials advancements have been reported recently, particularly in the area of Zn‐ion‐storing cathodes, the commercialization course of ZIBs is still being hindered by several key technical issues such as capacity, degradation, self‐discharge, etc. Recognizing that there are ample Reviews on ZIBs in the literature, the focus of this article is to specifically address the current development and critical challenges in ZIB electrodes and provide candid opinions for future commercialization of ZIBs. The Review starts with a brief introduction to ZIBs and their unique advantages in stationary energy storage, and then moves onto the current Zn‐ion storage mechanisms, progress and issues associated with cathodes and anodes. Finally, the Review is concluded with perspectives and directions of future ZIB development.

实用的可充电锌离子水电池电极材料：挑战与机遇

近年来，基于近中性水性电解质的可充电锌离子电池（ZIB）作为能量消耗，安全性，成本和环境影响方面的突出优点，已成为替代型大型固定式存储设备的积极研究。尽管最近已经报道了材料的显着进步，特别是在锌离子存储阴极领域，但是ZIBs的商业化进程仍然受到容量，降解，自放电等几个关键技术问题的阻碍。在文献中对ZIB进行了充分的评论，本文的重点是专门解决ZIB电极的当前发展和关键挑战，并为ZIB的未来商业化提供坦率的见解。该综述首先简要介绍了ZIB及其在固定式能量存储方面的独特优势，然后介绍了当前的Zn离子存储机理，进展以及与阴极和阳极相关的问题。最后，总结了未来ZIB发展的观点和方向。
