Abstract

As one of the most appealing energy storage technologies, aqueous zinc-iodine batteries still suffer severe problems such as low energy density, slow iodine conversion kinetics, and polyiodide shuttle. This review summarizes the recent development of Zn─I₂ batteries with a focus on the electrochemistry of iodine conversion and the underlying working mechanism. Starting from the fundamentals of Zn─I₂ batteries, the electrochemistry of iodine conversion and zinc anode, as well as the scientific problems existing in Zn─I₂ batteries are introduced. The concrete strategies dealing with cathode, anode, electrolyte, and separator challenges confronting Zn─I₂ batteries are elaborated as well. To deepen the understanding of the electrochemistry of Zn─I₂ batteries, the recent important findings of the underlying working mechanism of different Zn─I₂ batteries are summarized in detail. Finally, some guidelines and directions for Zn─I₂ batteries are also provided. This review is expected to deepen the understanding of Zn─I₂ battery electrochemistry and promote their practical applications in the future.

水性锌碘电池：从电化学到储能机制

作为最具吸引力的储能技术之一，水性锌碘电池仍然存在能量密度低、碘转化动力学慢和聚碘穿梭等严重问题。本文综述了锌的最新发展─I2电池，重点研究了碘的电化学转化及其潜在的工作机制。从锌的基本原理入手─I2电池，碘转化和锌阳极的电化学，以及锌中存在的科学问题─介绍了I2电池。应对锌面临的阴极、阳极、电解质和隔膜挑战的具体策略─I2电池也进行了阐述。加深对锌电化学的理解─I2电池，不同锌的潜在工作机制的最新重要发现─对I2电池进行了详细的总结。最后，Zn的一些指导方针和方向─还提供I2电池。这篇综述有望加深对锌的理解─I2电池电化学及其在未来的实际应用。
