Aqueous zinc-ion batteries (AZIBs) have gained increasing attention for grid energy storage systems. However, ensuring the long-term reversible operation of zinc anode remains a challenge due to dendrite growth and adverse side reactions during charge discharge cycles. This study investigates use d-pantothenic acid (D-PA) as an additive in 2 M ZnSO4 aqueous electrolyte enhance cycling stability AZIBs. Experimental results theoretical calculations demonstrate that D-PA reshapes solvation structure Zn2+ by partially replacing coordinated water molecules, transport. Furthermore, adsorbs on active sites anode, surface overpotential (|ηs|), reducing nucleation barrier, decreasing critical nucleus size (rcrit), thus uniform deposition. dual role modifying shell regulating effectively mitigates suppresses reactions, resulting excellent anode.

Enhanced Zinc Deposition and Dendrite Suppression in Aqueous Zinc‐Ion Batteries Via Citric Acid‐Aspartame Electrolyte Additives

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 24, 2025

Abstract Despite the advantages of low cost, safety, and environmental friendliness, aqueous zinc‐ion batteries (AZIBs) encounter challenges such as zinc dendrite formation, severe side reactions, electrolyte instability. Many effective additives exhibit limited solubility in water, thus reducing their practical application potential. In this study, a dissolution‐promoting strategy is proposed by introducing citric acid (CA) to enhance dissolution aspartame (APM), resulting sulfate electrolyte. Simulations experiments indicate that CA regulates both solvation structure Zn 2+ pH electrolyte, while APM preferentially integrates into electric double layer form solid interphase with CA, thereby suppressing hydrogen evolution reactions. Consequently, zinc‐zinc symmetric cell exhibits an extended lifespan over 4,500 h at 1.0 mA cm −2 /1.0 mAh . As result, AZIBs commercial foil MnO 2 enhanced rate capability improved capacity retention (75.6%) after 2,000 cycles. This study presents novel for stabilizing anodes offers comprehensive framework addressing fundamental AZIBs, advancing next‐generation energy storage systems.

Abstract Electrolyte additives are investigated to resolve dendrite growth, hydrogen evolution reaction, and corrosion of Zn metal. In particular, the electrostatic shielding cationic strategy is considered an effective method regulate deposition morphology. However, it very difficult for such a simple modification avoid competitive reactions, corrosion, interfacial pH fluctuations. Herein, multifunctional potassium phthalate (KHP) based on synergistic design anionic chemistry ultrastable Zn||I 2 full batteries demonstrated. K cations, acting as constructed smooth HP anions can enter first solvation shell 2+ reduced activities H O, while they remain in primary finally involved formation SEI, thus accelerating charge transfer kinetics. Furthermore, by situ monitoring near‐surface electrode, KHP effectively inhibit accumulation OH − by‐products. Consequently, symmetric cells achieve high stripping–plating reversibility over 4500 2600 h at 1.0 5 mA cm −2 , respectively. The deliver ultralong term stability 1400 cycles with high‐capacity retention 78.5%.
