“…For example, the I − anion and even the dual halogen anions (Br/Br − and Cl/Cl − ) in electrolyte could contribute capacity according to anionic redox reaction (Figure 3e). [27,47] In this zinc-dual halogen battery system with molten hydrate electrolyte, the graphite electrodes can sequentially accommodate intercalated Br − and Cl − , improving the capacity from 78 to 257 mA h g −1 compared with the conventional zinc-bromine batteries. There are also applications in aqueous ZIBs, which provide a new avenue for building high voltage batteries through using dual-ion battery system and "water-in-salt" electrolyte.…”

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.

Aqueous Zn-ion energy-storage deviceswith metal Zn as anodes, including batteries and capacitors (ZIBs and ZICs), is largely hindered by dendritic growth and low coulombic efficiency since the side reactions between Zn anodes and electrolyte, originating fromthat targeted and efficient isolation of H 2 O and SO 4 2− is extremely challenging. Herein, inspired by density functional theory (DFT) that the 2D angstrom level metal-organic framework(2D-MOF) is highly selective for the passage of ions, simultaneously excluding the SO 4 2− and H2O but allowing Zn 2 + selective conduction. Moreover, 2D-MOF exhibits better mechanical strength compared with 3D-MOF, which is more conducive to inhibit dendrite growth. Impressively, benefiting from the 2D-MOFlayer, symmetric Zn cells survived up to 2000 h at 4 mA cm −2 ,near 20-times that of bare Zn anodes. Coupling it with cathode for ZICs and ZIBs, excellent electrochemical performances are presented. Importantly, symmetric Na cells with 2D-MOF as ionic sieve membrane also deliver small polarization and outstanding performance, indicating that this study provides an efficient strategy to develop long-life metal anode.

Aqueous multivalent‐ion batteries (AMIBs) with features of environmental friendliness and cost‐efficiency are the most promising energy storage technologies for consumer electronics, electric vehicles, and grid‐scale energy storage. However, their practical application is severely impeded by the restricted capacity of electrode materials. Since chalcogen and halogen elements possess high specific capacities and low‐cost, the aqueous multivalent‐ion batteries based on chalcogen and halogen conversion are attractive due to the significant enhancement of specific energies. In this review, the advantages and recent progress of AMIBs based on chalcogen and halogen conversion chemistry have been systematically summarized with an emphasis on cell configuration, electrochemical performance, and storage mechanism. Furthermore, this review not only proposes challenges and perspectives for AMIBs, but also provides promising strategies for developing device‐scale applications. The above efforts may pave the way for the further development of high‐performance aqueous multivalent‐ion batteries with high safety and competitive performance.
