“…30 As is known to all, desolvated Zn 2+ cations or Zn atoms tend to diffuse laterally to the active site on the anode surface for deposition, and this will inevitably lead to Zn 2+ aggregate and then dendrite formation. 31 Fortunately, the adsorbed MelH + is capable of constraining the lateral diffusion of Zn 2+ , as indicated by the constant current aer the initial Zn nucleation process, 30,32 while an increasing trend of current is witnessed for the Zn anode tested in ZnSO 4 electrolyte. This phenomenon is mainly ascribed to the lower adsorption energy of Zn 2+ cations on the Zn surface covered by MelH + , indicating a large energy barrier for Zn 2+ lateral diffusion (Fig.…”

“…Similarly, the artificial ZnS layer retains its original protective properties without peeling off even after several repeated folding (Figure 18c) [134] . Moreover, the complex artificial SEI layers with the addition of the special elements, such as Zn 3 (PO 4 ) 2 /ZnF 2 ‐rich and Zn 3 (PO 4 ) 2 −ZnF 2 −ZnS composite layers, have also been used to modulate interfacial reactions (Figure 18d and e) [135,136] . The unique chemical inertness and high binding power of artificial SEI layers offer a practical possibility to build stable interfaces, and the strategy can be used to exploit the commercial zinc foils with inherent surface defects.…”

Owing to the properties of cost-efficient, high-energy density and environmental friendliness, rechargeable aqueous zincmetal batteries (RAZMBs) are promising candidates for the next generation metal-based batteries in large-scale energy storage systems. However, the practical applications of RAZMBs are severely limited due to the presence of inevitable side reactions referring to zinc corrosion and hydrogen evolution reaction (HER) occurring at the electrode-electrolyte interface. The uninterrupted interfacial side reactions at the expense of continuous capacity fading and reduced reversibility of zinc are required to give more attention to mitigate them. Given the above concerns, in this review, the fundamental principles of corrosion thermodynamics and kinetics of zinc electrodes in aqueous media are elucidated. Furthermore, the recent optimization strategies targeting enhanced stability of zinc electrodes are reviewed including electrolyte additives, zinc alloying, electrodeposited Zn and coating treatments. Finally, considering the current main research orientations, some perspectives are provided to facilitate the development of future applications of zinc anodes.

“…An artificial coating layer can effectively shield the ZMA from corrosion and suppress dendrite formation, but tedious treatment to the ZMA is required. [ 17–19 ] Electrolytes based on ionic liquids are generally electrochemically and thermally stable, but the high cost of ionic liquids hinders their widespread adoption. [ 20 ]…”

Aqueous Zn‐ion batteries (ZIBs) are a promising energy storage technology due to their intrinsic safety, eco‐friendliness, and cost‐effectiveness. However, aqueous electrolytes generally induce parasitic interfacial reactions (e.g., dendrite growth and passivation) that degrade the Zn metal anode, shortening ZIBs lifespan. This study develops a novel hydrated deep eutectic electrolyte (DEE), containing sulfolane (SL) and Zn(ClO4)2·6H2O, to prevent water‐induced deterioration. The strong coordination between SL and Zn2+ triggers the deep eutectic effect, extending the operating temperature window of the DEE. The unique water‐in‐DEE structure boosts ionic diffusion, promotes Zn2+ deposition, and reduces water reactivity, as revealed by in‐depth simulations and experiments. The developed DEE suppresses dendrite formation, allowing the Zn|DEE|Zn symmetrical cells to cycle over thousands of hours without short‐circuiting. With a polyaniline (PANI) cathode, Zn|DEE|PANI cells can cycle 2500 times with a capacity of 72 mAh g−1 at 3 A g−1 at room temperature and 500 times with 73 mAh g−1 at 0.3 A g−1 at −30 °C. The newly developed DEE significantly is a step forward for inexpensive, stable, and high‐performance ZIBs.
