Abstract Resting, a common procedure performed before cycling, is identified to have significant impact on the cycle performance of acidic aqueous zinc‐ion batteries (AZBs). It demonstrated that resting duration significantly affects Zn anode's cyclability and closely related evolution zinc hydroxide sulfate (ZHS), byproduct formed anode in AZBs, even without electrochemical cycling. Mechanism analysis suggests both uniformity quantity ZHS are critical factors determining electrode's cycling stability. Consequently, controlling interfacial effectively enhances electrode by preventing corrosion promoting uniform stripping/plating during an effective hydrothermal layer can protect electrode, rendering it less susceptible impacts, resulting long life over 3800 h at 2 mA cm −2 −0.5 mAh . With 30% depth discharge, this strategy helps extend >1000 h. (4 –2 ). The findings not only highlight importance standardizing period evaluating AZBs performance, but also lead relationship understanding among resting, evolution, cyclability, further guiding improve stability AZBs.

However, dendrites uncontrolled side reactions in anodes detract the cycle life density of batteries.

Abstract Enhancing cathodic performance is crucial for aqueous zinc‐ion batteries, with the primary focus of research efforts being regulation intrinsic material structure. Electrolyte also widely used to improve full‐cell performance, whose main optimization mechanisms have been extensively discussed only in regard metallic anode. Considering that ionic transport begins electrolyte, modulation electrolyte must influence or even reaction mechanism. Despite its importance, discussion effects on cathode has not garnered attention it deserves. To fill this gap and raise awareness importance mechanisms, review comprehensively combs underlying strategies classifies into three categories according their commonalities first time, which are ion effect, solvating interfacial revealing missing puzzle piece optimizing cathode.

Voltaic pile, the very first battery built by humanity in 1800, plays a seminal role development history. However, premature design leads to inevitable copper ion dissolution issue, which dictates its primary nature. To address this solid-state electrolytes, exchange membranes, and/or sophisticated electrolytes are widely utilized, leading high costs and complicated cell configuration. Herein, we build rechargeable zinc–copper voltaic from simple cheap electrolyte/separator materials, thus eliminating need use above components. Notably, our leverages Zn4SO4(OH)6·xH2O precipitation ZnSO4 common side reaction zinc batteries, provide "locally alkaline" environment for electrodes. Consequently, oxide (O2–) anion insertion takes place readily transforms copper(I) (Cu2O) without any issue. Therefore, realizes capacity of ∼370 mA h g–1 long cycling ∼500 cycles. Our work provides an innovative approach stabilize metal electrodes energy storage.

The formation of non-ion conducting byproducts on zinc anode is notoriously detrimental to aqueous zinc-ion batteries (AZIBs). Herein, we successfully transform a representative byproduct, crystalline hydroxide sulfate (ZHS) fast-ion solid-electrolyte interphase (SEI) via amorphization and fluorination induced by suspending CaF2 nanoparticles in dilute electrolytes. Distinct from widely reported nonhomogeneous organic–inorganic hybrid SEIs that exhibit structural chemical instability, the designed single-phase SEI homogeneous, mechanically robust, chemically stable. These characteristics facilitate prevention dendrite growth reduction capacity loss during long-term cycling. Importantly, AZIB full cells based this SEI-forming electrolyte exceptional stability over 20,000 cycles at 3 A/g with charging voltage 2.2 V without short circuits dry-out. This work suggests avenues for designing metal provides insights into associated chemistry.

Abstract Aqueous zinc‐ion batteries (AZIBs) are of interest in next‐generation energy storage applications owing to their safety, environmental friendliness, and cost‐effectiveness. Vanadium‐based oxides promising cathodes for AZIBs due appropriate structure multielectron redox processes. Although hundreds studies devoted understanding the mechanisms developing high‐performance vanadium‐based cathodes, many puzzles controversies still exist, especially regarding two representative by‐products, basic zinc salt (BZS) pyrovanadate (ZVO). BZS ZVO often observed on cathode anode during cycling, directly affecting battery performance. However, by‐products’ controversial unclassified insights unclear have severely limited Zn‐V batteries’ progress. Therefore, this review aims exhaustively elucidate “past present” by‐products following a logical sequence origin, role, inhibition strategy, prospect. Notably, incorporates substantial comments understandings long‐neglected issues related BZS‐related ZVO‐related dissolution mechanisms. This is expected provide scientific guidelines future optimization commercialization batteries.
