“…This could be caused by a decrease in the electron cloud density of H atom in H 2 O, owing to the interaction of Zn 2+ with both H 2 O and cosolvent molecules. [24,25] The results above suggest that the EG component possessed the most robust solvent reconstruction capability. EG solvent could induce the displacement of water molecules from hydrated Zn ion ([Zn(H 2 O) 6 ] 2+ ) and the water molecules released could cluster with various molecules.…”

As a new generation of lithium‐ion battery alternative, aqueous zinc (Zn) ion batteries (ZIBs) garner tremendous interests for future energy storage application owing to their inherent incombustible, nontoxic, and low‐cost features. However, their practical utilization is hampered by the electrolyte freezing at subzero conditions. In this study, a novel high‐entropy (HE) electrolyte fabricated is presented with hybrid solvents to mitigate electrolyte freezing at low temperatures, restrain calendar corrosion, and boost Zn‐ion transfer kinetics. Specifically, the isovolumetric combined ethyl acetate, ethylene glycol, and dimethyl sulfoxide as solvent components not only induce a reconfiguration of hydrogen bonding, but also alter the solvation sheath of Zn ions within the HE electrolyte environment. This synergistic coupling of hybrid co‐solvents effectively harnesses the features of individual solvent additive and facilitates the remarkable advantages on cycling reversibility, especially in the low‐temperature conditions. Benefiting from the anti‐freezing and solvation structure regulation features, Zn symmetrical batteries equipped with HE electrolytes can work over 2500 h in low zinc salt concentration (1 m) at various temperatures. This work provides a facile modulation strategy to achieve the HE electrolyte, promoting the practical application and commercialization of advanced ZIBs with wide‐temperature adaptability.

“…Compared to CNTs, G has a larger specific surface area (SSA) and similar Young's modulus (∼1.0 TPa), which is conducive to a stronger supporting effect. 14 Hence, compared with N–CNFs (Fig. 1a and d), the supporting effect of CNT and G induces more pore structure on the CNFs (Fig.…”

“…However, polyethylene glycol diacid (PEGDA) with antifreezing ability was proposed to remove surface by-products through creating a strong acid environment. [147] As a result, no obvious peak was detected in Raman spectrum, indicating the enhanced inhibition of anode corrosion. The existence of highly active water can destroy anode, but removing all water will make ZIBs lose the intrinsic advantages like safety, fast ion conduction and so on.…”

The growing environmental pollution issues and continuous energy dilemma call for high‐performance energy storage systems (ESSs). While the inevitable safety concerns appear and restrict the application of lithium‐ion batteries in large‐scale ESSs. Contrastively, zinc ion batteries (ZIBs) attract increasing attention due to the inherent advantages of high safety, low cost, and environmental friendliness. However, the poor stability and reversibility of Zn anodes bring severe difficulty for its practical application. Considerable efforts are devoted in the anode modification, such as electrolyte adjustment, interfacial engineering, and anode structure design, but there is still a fuzzy field concerning the reaction process, regulation mechanism, and modified effect. Reviewing the history, the development of various electrodes greatly depends on the breakthrough in advanced characterization technologies, while the summarizations of technological advances in the Zn anode are still deficient. Hence, this review concentrates on the recent progress in various characterization techniques and related strategies of anode protection. The information is especially highlighted that each technique can offer the crucial or auxiliary role they play in proving specific issues. Furthermore, the opinions on current limitations and future directions of common characterization techniques are also discussed in detail, aiming to give a comprehensive perspective in designing advanced zinc anodes.
