Abstract

Aqueous Zn batteries (ZBs) are promising candidates for large-scale energy storage, considering their intrinsically safe features, competitive cost, and environmental friendliness. However, the fascinating metallic Zn anode is subjected to severe issues, such as dendrite growth, hydrogen evolution, and corrosion. Additionally, traditional aqueous electrolytes' narrow electrochemical windows and temperature ranges further hinder the practical application of ZBs. Solid-state electrolytes, including solid polymer electrolytes and hydrogel electrolytes, offer distinct paths to mitigate these issues and simultaneously endow the ZBs with customizable functions such as flexibility, self-healing, anti-freezing, and regulated Zn deposition, etc, due to their tuneable structures. This review summarizes the latest progress in developing polymer electrolytes for ZBs, focusing on modifying the ionic conductivity, interfacial compatibility, Zn anode stability, electrochemical stability windows, and improving the environmental adaptability under harsh conditions. Although some achievements are obtained, many critical challenges still exist, and it is hoped to offer guidance for future research, accelerating the development and application of polymer electrolytes.

先进锌电池用聚合物电解质的研究进展。

考虑到其本质安全、具有竞争力的成本和环境友好性，水锌电池（ZBs）是大规模储能的有希望的候选者。然而，令人着迷的金属锌阳极受到严重的问题，如枝晶生长，析氢和腐蚀。此外，传统水性电解质的电化学窗口和温度范围较窄，进一步阻碍了ZBs的实际应用。固态电解质，包括固体聚合物电解质和水凝胶电解质，提供了不同的途径来缓解这些问题，同时赋予zb可定制的功能，如灵活性、自修复、防冻和调节锌沉积等，由于其可调谐的结构。本文综述了ZBs聚合物电解质的最新研究进展，重点从离子电导率、界面相容性、Zn阳极稳定性、电化学稳定窗口以及改善恶劣条件下的环境适应性等方面进行了综述。虽然取得了一些成果，但仍存在许多关键挑战，希望对未来的研究提供指导，加快聚合物电解质的开发和应用。
