Abstract

Abstract : With the merit of high capacity, high safety, and low cost, zinc‐ion batteries (ZIBs) possess huge application potential in the domain of large‐scale energy storage. However, due to the relatively narrow voltage window and large lattice distortion of cationic redox reaction, ZIBs tend to present low energy density, poor kinetics, and unstable cyclic performance. Anion chemistry seems to provide a novel strategy to solve these issues from different aspects, such as enhanced operating voltage, extra capacity contribution, and boosted reaction kinetics. Considering the significance of this theory and the lack of relevant literatures, herein, in‐depth comprehension of anionic chemistry and its positive effects on zinc storage performance have been emphasized and summarized. This review aims to present a full scope of anionic chemistry and furnish systematic cognition for rational design of advanced ZIBs with high energy density. Furthermore, insightful analysis and perspectives based on the current research status also have been proposed, which may point out some scientific suggestions and directions for the future research. Abstract : This review aims to present comprehensive understanding of anionic chemistry involving anionic redox reaction, electrode modification as well as electrolyte regulation in ZIBs, and promote the development of advanced secondary battery with high‐energy density and low cost.
