Abstract

Rechargeable Zn-based batteries are gaining increased interest for use in energy storage systems due to their inherent safety, affordability, and eco-friendliness. Zn powder is highly regarded as a promising material for Zn-based batteries due to its cost-effectiveness, superior electrochemical performance and ease of processing, as well as customizable utilization rate, which holds great potential in increasing overall energy density of Zn-based batteries. However, the commercialization of Zn powder anodes still remains great challenges such as more severe hydrogen evolution, volume effect caused electrical contact failure, poor macroscopic mechanical strength in comparison with zinc foils and additional short circuits due to dendrite growth. This topical review focuses on the recent research advance of Zn power-based anodes. A comprehensive organization of the previously reported benefits and challenges in Zn powder anode is firstly provided. Then, the advancements in structural design strategies of Zn powder anodes, and the corresponding electrochemical performance are discussed in detail. Finally, the future challenges in developing practical Zn powder anode based on crystallography, mechanics, electrode process engineering and other related fields are examined. This review offers a fresh perspective on designing Zn powder anodes for use in commercial Zn-based energy storage systems in the future.

锌粉阳极结构设计策略--实现锌基可充电电池

可充电锌基电池因其固有的安全性、经济性和环保性，在储能系统中的应用日益受到关注。锌粉因其成本效益高、电化学性能优越、易于加工以及可定制的利用率而被认为是一种很有前途的锌基电池材料，在提高锌基电池的整体能量密度方面具有巨大潜力。然而，锌粉阳极的商业化仍面临巨大挑战，例如氢演化更加严重、体积效应导致电接触失效、与锌箔相比宏观机械强度较差以及枝晶生长导致的额外短路。本专题综述重点介绍了锌动力阳极的最新研究进展。首先全面梳理了之前报道的锌粉阳极的优势和挑战。然后，详细讨论了锌粉阳极结构设计策略的进展以及相应的电化学性能。最后，研究了基于晶体学、力学、电极工艺工程和其他相关领域开发实用锌粉阳极的未来挑战。这篇综述为设计未来用于商用锌基储能系统的锌粉阳极提供了一个全新的视角。
