Abstract

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─I 2 batteries with a focus on the electrochemistry of iodine conversion and the underlying working mechanism. Starting from the fundamentals of Zn─I 2 batteries, the electrochemistry of iodine conversion and zinc anode, as well as the scientific problems existing in Zn─I 2 batteries are introduced. The concrete strategies dealing with cathode, anode, electrolyte, and separator challenges confronting Zn─I 2 batteries are elaborated as well. To deepen…
