Article Abstract
The poor Zn reversibility has been criticized for limiting applications of aqueous Zn-ion batteries (ZIBs); however, its behavior in aqueous media is not fully uncovered yet. Here, this knowledge gap is addressed, indicating that Zn electrodes face a O -involving corrosion, besides H evolution and dendrite growth. Differing from aqueous Li/Na batteries, removing O cannot enhance ZIB performance because of the aggravated competing H evolution. To address Zn issues, a one-off electrolyte strategy is reported by introducing the triple-function C H Na O P, which can take effects during the shelf time of battery. It regulates H concentration and reduces free-water activity, inhibiting H evolution. A self-healing solid/electrolyte interphase (SEI) can be triggered before battery operation, which suppresses O adsorption corrosion and dendritic deposition. Consequently, a high Zn reversibility of 99.6% is achieved under a high discharge depth of 85%. The pouch full-cell with a lean electrolyte displays a record lifespan with capacity retention of 95.5% after 500 cycles. This study not only looks deeply into Zn behavior in aqueous media but also underscores rules for the design of active metal anodes, including Zn and Li metals, during shelf time toward real applications.

Pre-intercalation has emerged as a highly effective strategy to enhance structural integrity and ion transport kinetics in cathodes for aqueous Zn-ion batteries. Here, we report a zinc-ion pre-intercalated hydrate vanadium oxide cathode, in which the initial insertion of Zn induces a significant expansion of the interplanar spacing, followed by contraction at higher Zn concentrations owing to strong electrostatic interactions with the VO framework. Such competing expansion and contraction of interplanar spacing enhances the overall electrochemical properties.

Interfacial instability, particularly uncontrollable zinc deposition and water induced side reactions, severely compromises the cycling stability and lifespan of aqueous zinc-ion batteries (AZIBs), thereby hindering their commercialization. Herein, an in situ grown bilayer gradient hydrophobic artificial interface (ZFPB) is designed to achieve dendrite-free zinc deposition. In detail, the ion-conductive but electronically insulating ZnF outer layer facilitates the rapid migration of Zn.

Dendritic growth and parasitic reactions severely hinder aqueous Zn-ion batteries due to interfacial instability and uncontrolled charge transfer. Here, a machine learning-accelerated strategy for rational additive screening, establishing a predictive framework that links the highest occupied molecular orbital (HOMO) energy level to the adsorption and reduction behavior of Zn, is reported. An interpretable machine learning model (Adaptive Boosting), trained on a curated molecular dataset, achieves high accuracy (Mean Squared Error = 0.

Aqueous zinc (Zn) metal electrodeposition-based electrochromic windows (AZWs) are a promising dynamic window technology due to their use of low-cost, nonflammable, nontoxic, and highly conductive aqueous electrolytes. However, their development is hindered by issues such as poor reversibility, byproduct formation, and hydrogen evolution, which limit the optical window and cycling lifespan. Herein, a bionic transparent nanogel interlayer (TGI) in triple-layer structure introduced on both Zn electrode and indium tin oxide (ITO) glass electrode is demonstrated to achieve highly reversible electrochemical reaction.

Rechargeable aqueous zinc-ion batteries (AZIBs) have become a viable option in electrochemical energy storage systems (EESS) owing to their inherent safety features and economic friendliness. Nonetheless, creating suitable cathode materials for AZIBs with high structural stability, good rate performance, and great capacity remains a significant challenge. Polyoxometalate (POM)-based nanohybrid materials have shown promising results in high cycling stability and great specific capacity.
