Abstract

Aqueous zinc-ion batteries (AZIBs) have emerged as a promising alternative to lithium-ion batteries (LIBs) due to their high safety, low cost, and environmental friendliness. However, aqueous electrolytes face inherent challenges such as freezing at low temperatures and water loss at high temperatures. Achieving reliable operation of AZIBs under extreme conditions remains a significant challenge and has attracted considerable research attention. Furthermore, extreme temperatures can exacerbate parasitic side reactions, including hydrogen evolution reaction (HER) and zinc dendrite formation. This review begins by outlining the failure mechanisms of AZIBs under various temperature conditions, followed by a comprehensive discussion of design strategies to mitigate these issues. Various electrolyte optimization approaches are examined, including solute optimization, functional additives, cosolvents, ionic liquids, deep eutectic electrolytes, and hydrogel-based systems. The article provides a detailed overview of the basic components, operating principles, and unique features of wide-temperature-range AZIBs. Additionally, persistent challenges and bottlenecks regarding AZIBs are summarized, together with constructive perspectives and future research directions. This review aims to offer valuable insights and practical guidelines for developing next-generation electrolyte systems for high-quality, wide-temperature-range AZIBs.

电解液设计策略，失效机制，以及宽温度范围水锌离子电池的未来前景

水性锌离子电池（AZIBs）因其高安全性、低成本和环保性而成为锂离子电池（LIBs）的一个有前途的替代品。然而，含水电解质面临着固有的挑战，例如在低温下冻结和在高温下失水。在极端条件下实现azib的可靠运行仍然是一个重大挑战，并引起了相当大的研究关注。此外，极端温度会加剧寄生副反应，包括析氢反应（HER）和锌枝晶的形成。本文首先概述了azib在各种温度条件下的失效机制，然后全面讨论了减轻这些问题的设计策略。研究了各种电解质优化方法，包括溶质优化、功能添加剂、共溶剂、离子液体、深共晶电解质和基于水凝胶的系统。本文详细介绍了宽温度范围azib的基本组成、工作原理和独特功能。此外，总结了azib的持续挑战和瓶颈，并提出了建设性的观点和未来的研究方向。本综述旨在为开发高质量、宽温度范围azib的下一代电解质系统提供有价值的见解和实用指南。
