Abstract

Aqueous zinc-iodine batteries (AZIBs) exhibit intrinsic safety, cost-effectiveness, extended service life, and environmental sustainability, demonstrating promising application prospects. Nevertheless, the sluggish kinetics of iodine conversion reactions, the “shuttle effect” of polyiodides, and the instability of high-valence iodine species in aqueous electrolytes limit their reversibility and energy density. By summarizing the recent advances in electrolytes for AZIBs, including material design and mechanistic investigations, this review provides a comprehensive overview of energy storage mechanisms based on iodine conversion chemistry, emphatically analyzes the underlying roots of the above challenges, and highlights the critical role of electrolyte optimization in enhancing the reversibility and energy density of AZIBs. Building on these insights, guidelines and future research directions for AZIBs are proposed. This review aims to provide a valuable reference for developing AZIBs and facilitating their commercial applications.

在水锌碘电池中实现高可逆和高能量阴极：电解质途径

水性锌碘电池（azib）具有固有的安全性、成本效益、延长使用寿命和环境可持续性，具有广阔的应用前景。然而，碘转化反应的缓慢动力学、多碘化物的“穿梭效应”以及高价碘在水电解质中的不稳定性限制了它们的可逆性和能量密度。本文综述了近年来azib电解质的研究进展，包括材料设计和机理研究，全面概述了基于碘转化化学的储能机制，重点分析了上述挑战的根本原因，并强调了电解质优化在提高azib可逆性和能量密度方面的关键作用。在此基础上，提出了azib的指导方针和未来的研究方向。本文旨在为azib的开发和商业化应用提供有价值的参考。
