Abstract While aqueous zinc metal batteries (AZMBs) have shown great promise for large‐scale energy storage, a series of interfacial side reactions derived from the decomposition active water molecules in Zn 2+ solvation structures seriously hinder practical application AZMBs. Recently, regulating electrolytes has been proven to be effective alleviating reactions. Advanced characterization techniques probe provide powerful tools comprehensively understanding underlying relationship between and performance Although significant processes achieved electrolyte engineering mechanistic preliminarily established, systematic summary is still absent. Considering importance engineering, comprehensive review this topic necessary. In article, advantages scope ever‐used studying are introduced remaining challenges potential opportunities future discussed.

Abstract The electrochemical instability of electrode/electrolyte interface and aqueous electrolyte collectively brings technical barriers, such as side reactions like hydrogen evolution corrosion, well zinc dendrites, which hinder the practical application batteries. Here, an engineering strategy is proposed with asymmetric spatial shielding effect by employing molecules structure a cosolvent. Such molecule contains small methyl group large cyclopentyl to balance migration capability volume, can not only promote solvation Zn 2+ containing more anions solid derived from abundant but also rapidly effectively adsorb on surface anode remodel electric double layer. This alleviates corrosion while achieving dendrite‐free deposition. Consequently, Zn/I 2 cell operate stably at A g −1 for 30 000 cycles over 180 days, capacity retention 79.8%. Despite featuring cathode areal 4.74 mAh cm −2 N/P ratio 2.5, Zn/NH 4 V O 10 still achieves impressive 88.8% 0.5 200 cycles, demonstrating significant potential application.

Abstract Aqueous Zn/V 2 O 5 batteries are featured for high safety, low cost, and environmental compatibility. However, complex electrode components in real impede the fundamental understanding of phase transition processes intercalation chemistry. Here, model based on V film electrodes which show similar electrochemical behaviors as ones built. Advanced surface science characterizations allow to identify trajectories Zn 2+ , H O, + during processes. Protons serve vanguard intercalated species, facilitating subsequent O. The increase capacity activation process is mainly due from more active ·nH structure caused by partial irreversible deintercalation rather than sites induced grain refinement materials. Eventually, accumulation species within oxide results formation inactive (Zn 3 (OH) 7 ·2H O) structure. established chemistry helps design high‐performance

Abstract Recent years have witnessed a surge in research on aqueous zinc‐ion batteries (AZIBs) due to their low cost, stability, and exceptional electrochemical performance, among other advantages. However, practical manufacturing deployment of AZIBs been hindered by challenges such as energy density, significant precipitation‐related side reactions, slow ion migration, dendritic growth. Addressing these issues enhancing the application necessitates development novel materials. Carbon dots (CDs), with distinctive structure superior properties, represent an innovative class carbon‐based materials broad potential applications for optimizing AZIBs' performance. This study offers comprehensive review how CDs can address aforementioned AZIBs. It begins overview composition mechanism before delving into classification, preparation techniques, functionalization strategies CDs. The also thoroughly summarizes sophisticated roles modifiers electrolytes electrodes, both positive negative, briefly discusses membranes. Additionally, it provides summary current difficulties encountered utilizing aims provide insights guidance designing next generation high‐performance
