“…To demonstrate the practical applications of the advanced zinc anode, the aqueous ZnI 2 battery was fabricated with the iodine loaded N, P co‐doped porous carbon (Figure S24, Supporting Information) as a cathode in consideration of the abundant iodine element in seawater. [ 39 ] As shown in Figure a, the reversible redox peaks with the largest area is related to the enhanced specific capacity of the battery with PA‐Zn anode. In addition, the small potential difference between the redox peaks suggests the good reversibility of zinc with the fast conversion process of iodine.…”

Alternatively, zinc with large theoretical capacity (gravimetric capacity −820 mAh g −1 and volumetric capacity −5855 mAh cm −3 ), appropriate low potential (−0.762 V versus standard hydrogen electrode) and good stability than alkaline metals, is particularly attractive in the scientific and technological areas. [2] For example, the alkaline zincmanganese dioxide batteries have been commercially used as the specific primary battery.

“…[40] In addition, eutectic electrolytes without water contents possibly prevent problems caused by Zn dendrite growth and side reactions. [86] Analogous, some research related to Zn anodes protection and modification promotes the nonaqueous eutectic electrolytes for ZIBs, [44,87] Zn-S batteries, [65] Zn-I 2 batteries, [88] and Zn-Fe flow batteries. [8b] Zn-based eutectic electrolytes, constitute mixing anhydrous/ hydrated Zn metal with quaternary ammonium salts (e.g., ChCl) or HBDs (e.g., urea, acetamide, and ethylene glycol).…”

Rechargeable zinc batteries (RZBs) have proved to be promising candidates as an alternative to lithium‐ion batteries due to their low cost, inherent safety, and environmentally benign features. While designing cost‐effective electrolyte systems with excellent compatibility with electrode materials, high energy/power density as well as long life‐span challenge their further application as grid‐scale energy storage devices. Eutectic electrolytes as a novel class of electrolytes have been extensively reported and explored taking advantage of their feasible preparation and high tunability. Recently, some perspectives have summarized the development and application of eutectic electrolytes in metal‐based batteries, but their infancy requires further attention and discussion. This review systematically presents the fundamentals and definitions of eutectic electrolytes. Besides, a specific classification of eutectic electrolytes and their recent progress and performance on RZB fields are introduced as well. Significantly, the impacts of various composing eutectic systems are disserted for critical RZB chemistries including attractive features at electrolyte/electrode interfaces and ions/charges transport kinetics. The remaining challenges and proposed perspectives are ultimately induced, which deliver opportunities and offer practical guidance for the novel design of advanced eutectic electrolytes for superior RZB scenarios.

“…[3] Fortunately, aqueous zinc batteries (AZBs) may solve the above issues with aqueous electrolyte applied. [4] Besides, the zinc anode provides non-toxic nature and a high theoretical capacity (820 mAh g À 1 ), [5] contributing to the high cost-efficiency and simple assembly of AZBs. [6] As one of the generally used cathode materials in AZBs, wide attention and research have been focused on the energy storage mechanisms and optimization strategies of manganese dioxide (MnO 2 ).…”

Aqueous Mn 2 + /MnO 2 -based batteries have attracted enormous attentions in aqueous energy storage fields, owing to their high working voltage and theoretical capacity (616 mAh g À 1 ) brought by the two-electron reaction (Mn 2 + /Mn 4 + ). However, there are currently several tricky challenges facing Mn 2 + /MnO 2 -based batteries: their complicated working mechanisms, existing issues, and optimization strategies. This Perspective aims to provide a mechanistic understanding and an overview of the insufficiency, optimization, and future development for Mn 2 + / MnO 2 -based batteries. The existing issues and deficiency in Mn 2 + /MnO 2 -based batteries have been systematically analyzed, and optimization strategies have also been rationally summarized and discussed with deep insights. Also, the often-overlooked optimized objects and aspects have been highlighted with unique perspectives. The proposals of testing methods and performance assessment are presented, containing different degradation mechanisms. Based on the above points, this Perspective will provide guidance and contribute to the further development of aqueous Mn 2 + /MnO 2 -based batteries.
