Abstract The performance of aqueous zinc‐ion batteries (AZIBs) at high temperatures (HT) is severely compromised by active water corrosion, parasitic reactions, and dendrite growth. Herein, zinc trifluoroacetate introduced a low concentration (0.2 m ), dissolved in triethyl phosphate (TEP)and H 2 O. suppressed due to the reconstructed original hydrogen bond network, which helps inhibit reactions severe corrosion. Meanwhile, solid electrolyte interphase (SEI) formed on anode decomposition salt. high‐tolerance SEI physically separates anode, reducing corrosion caused water. Moreover, TEP, as prevalent fire‐retardant cosolvent, can preferentially anchor sheet, serving shielding buffer layer. TEP not only reconstructing structure electric double layer (EDL), decreasing content water, but also accelerating prompt formation further. As proof this synergistic effect, assembled symmetric Zn.

Zinc (Zn) metal, with abundant resources, intrinsic safety, and environmental benignity, presents an attractive prospect as a novel electrode material. However, many substantial challenges remain in realizing the widespread application of aqueous Zn-ion batteries (AZIBs) technologies. These encompass significant material corrosion (This can lead to battery failure unloaded state.), hydrogen evolution reactions, pronounced dendrite growth at anode interface, constrained electrochemical stability window. Consequently, these factors contribute diminished lifespan energy efficiency while restricting high-voltage performance. Although numerous reviews have addressed potential separator design mitigate issues some extent, inherent reactivity water remains fundamental source challenges, underscoring necessity for precise regulation active molecules within electrolyte. In this review, mechanism AZIBs (unloaded charge discharge state) is analyzed, optimization strategy working principle electrolyte are reviewed, aiming provide insights effectively controlling process reaction, further formation, expanding range stability. Furthermore, it outlines promote its practical future development pathways.

The performance of zinc-ion batteries (ZIBs) is often hindered by issues such as dendrite formation, hydrogen evolution, and limited cycling stability. 1,3-Dihydroxyacetone (DHA) not only stabilizes the anode modulating anode/electrolyte interface (AEI) but also enhances electrochemical battery through its spontaneous reversible keto-enol tautomerization, reducing concentration gradient on surface. Using a combination DFT calculations experimental characterization, regulation hydrated Zn2+ structure adsorption at AEI this additive investigated. Overall, incorporating DHA extends stability Zn||Zn symmetric to 400 h, even depth discharge 56.7% (DOD). Zn||VNNC full exhibit stable for 700 cycles 5 A g-1 with low N/P ratio (2.69), while Zn||AC capacitors (ZICs) significantly enhanced. This study evaluates potential in ZIBs dynamic characteristics molecular structures.

Zinc-ion secondary batteries have been competitive candidates since the "post-lithium-ion" era for grid-scale energy storage, owing to their plausible security, high theoretical capacity, plentiful resources, and environment friendliness. However, many encumbrances like notorious parasitic reactions Zn dendrite growth hinder development of zinc-ion remarkably. Faced with these challenges, eutectic electrolytes aroused notable attention by virtue feasible synthesis tunability. This review discusses definition advanced functionalities in detail divides them into nonaqueous, aqueous, solid-state regard state component electrolytes.
