Water-induced side reactions and unfavorable undesirable growth have restricted the further development of aqueous zinc-ion batteries. Electrolyte additives are considered as a pragmatic and viable approach to address this issue, owing to their ease of operation and satisfactory compatibility. This study identifies diprophylline as a promising additive for electrolytes, underscoring its favorable adsorption energy with zinc metal. The selective adsorption of diprophylline has been demonstrated to engender two primary effects. Firstly, it reconstructs a water-lean electric double layer, and secondly, it enhances the textured growth of Zn(002). Furthermore, diprophylline weakens the coordination bonding between Zn 2+ and H 2 O to regulate the solvation structure of Zn 2+ . Consequently, the zinc symmetric battery functions stably for over 2900 h at 5 mA cm −2 . The Zn||Cu asymmetric battery displays an average coulombic efficiency as high as 99.89 % across 4000 cycles. This research presents an affordable and easily operable electrolyte modification method for developing a Zn anode/electrolyte interface that exhibits excellent stability and reversibility.

Phosphoric acid etching combined with hydrothermal treatment was used to construct a Sc 2 O 3 -ZnO coating on the Zn anode surface to tune the content of Zn (002) crystal surface. The (002) crystalline surface of Zn surface became the preferred crystal face for the H 3 PO 4 etching time of 7 min and hydrothermal reaction for 2 h at 160°C. The polarization curve results showed that in 2 M of ZnSO 4 solution, the corrosion potential of Zn anode with (002) crystallographically optimal orientation was positively shifted by 663 mV and the corrosion current density was reduced by about four orders of magnitude compared with the bare Zn. The results of LSV and XRD showed that the Zn anode with (002) preferred crystal face possessed a more negative hydrogen evolution potential, which effectively hindered the occurrence of the H 2 evolution side reaction and significantly inhibited the corrosion of metal Zn and the generation of alkaline zinc sulfate hydrate as a byproduct. Dense Sc 2 O 3 -ZnO coatings composed of crosslinked nanofibers provided a long-lasting and effective shielding protection. The coating facilitated the induction of Zn (002) crystal face oriented deposition, and the bonding of N or P enhanced the stability of coating, which significantly enhanced the corrosion resistance.

The nonuniform electric field at the surface of a zinc (Zn) anode, coupled with water-induced parasitic reactions, exacerbates the growth of Zn dendrites, presenting a significant impediment to large-scale energy storage in aqueous Zn-ion batteries. One of the most convenient strategies for mitigating dendrite-related issues involves controlling crystal growth through electrolyte additives. Herein, we present thiamine hydrochloride (THC) as an electrolyte additive capable of effectively stabilizing the preferential deposition of the Zn(002) plane. First-principles calculations reveal that THC tends to adsorb on Zn(100) and Zn(101) planes and is capable of inducing the deposition of Zn ion onto the (002) plane and the preferential growth of the (002) plane, resulting in a flat and compact deposition layer. A THC additive not only effectively suppresses dendrite growth but also prevents the generation of side reactions and hydrogen evolution reaction. Consequently, the Zn||Zn symmetric battery exhibits long-term cycling stability of over 3000 h at 1 mA cm–2/1 mAh cm–2 and 1000 h at 10 mA cm–2/10 mAh cm–2. Furthermore, the NH4V4O10||Zn full battery also displays excellent cycling stability and a high reversible capacity of 210 mAh g–1 after 1000 cycles at 1 A g–1, highlighting a significant potential for practical applications.

Aqueous zinc batteries are promising candidates for large-scale energy storage owing to their intrinsic safety and low cost, yet their practical deployment remains hindered by parasitic interfacial reactions, unstable Zn deposition, and dendrite growth. Herein, we report a molecular-mediated elecAtrolyte strategy employing propionamide (PA) to stabilize Zn metal anodes through solvation–interface coupling regulation. PA partially replaces coordinated H 2 O molecules in the Zn 2+ solvation sheath and simultaneously reorganizes the hydrogen-bond network, thereby reducing H 2 O activity and mitigating water-induced parasitic reactions. Meanwhile, PA exhibits a strong affinity toward Zn surfaces, forming a stable adsorption environment that modulates interfacial reaction kinetics. Theory calculations reveal preferential adsorption of PA on Zn facets, which promotes thermodynamically favored Zn(002)-oriented growth. Consequently, Zn deposition evolves into dense and smooth layers with a highly textured crystallographic orientation and effectively suppressed dendrite formation. Owing to this solvation–interface coupled regulation, Zn||Zn symmetric cells achieve stable cycling for over 3800 h at 1 mA cm −2 and 1 mAh cm −2 , while Zn||VO 2 full cells maintain highly reversible operation for more than 10,000 cycles. This work establishes solvation–interface coupling regulation as an effective electrolyte-design principle for directing Zn crystallization and stabilizing aqueous zinc batteries. The electrolyte with propionamide (PA) additive achieves dendrite-free and durable aqueous Zn batteries by coupling Zn 2+ solvation reconstruction with interfacial adsorption, reducing water activity, stabilizing pH, and guiding the preferential deposition of Zn on the (002) crystal plane.

The practical application of aqueous zinc-ion batteries (AZIBs) is significantly hindered by the unregulated growth of dendrites and the instability at the interface of Zn anodes. Here, we report an interfacial engineering strategy using ionic liquid modified electrolytes to achieve uniform Zn deposition and long-term stability. Two imidazolium-based ionic liquids, 1-butyl-3-methylimidazolium chloride (BmCl) and 1-butyl-3-methylimidazolium bromide (BmBr), were incorporated to regulate Zn 2+ solvation structure and interfacial behavior. The imidazolium cation (Bm + ) exhibits preferential adsorption on the Zn(002) facet, forming a compact protective layer, while halide anions (Cl − /Br − ) tune Zn 2+ desolvation and migration kinetics. Combined spectroscopic and theoretical analyses reveal that BmBr possesses a higher desolvation energy and stronger interfacial regulation capability, which effectively promote selective Zn(002) oriented growth and suppress dendrite formation. As a result, Zn||Zn symmetric cells using the BmBr/ZnSO 4 (BmBr/ZSO) electrolyte demonstrate exceptional cycling stability, maintaining performance for over 5000 h at 0.5 mA cm −2 and 0.5 mAh cm −2 . Furthermore, Zn||NVO full cells exhibit a remarkable specific capacity of 401 mAh g −1 at 0.1 A g −1 , along with excellent cycling stability. The BmBr/ZSO electrolyte also effectively suppresses self-discharge. This study elucidates the underlying mechanisms of cation-anion driven regulation and presents a broadly applicable approach for developing high-performance, dendrite-free AZIBs.

Zn metal anode in aqueous zinc-ion batteries (AZIBs) suffers from dendrite growth, hydrogen evolution reaction (HER), and surface passivation, deteriorating battery performance and practicality. The structural engineering of anode with more exposed Zn (002) crystal planes (Zn (002) texture) is considered an effective strategy to achieve uniform and dendrite-free zinc deposition. Current approaches for fabricating Zn (002) texture primarily involve heat treatment, rolling, electrochemical etching, and deposition techniques; however, these methods are often associated with complex operational procedures or reliance on specialized equipment. In this study, a simple surface treatment was employed to treat Zn foil using a corrosion agent containing SeS, resulting in the successful fabrication of Zn C (corrosion-treated Zn foil) with a high proportion of Zn (002) as the anode material for AZIBs. Compared to bare Zn, the relative texture coefficient (RTC) of the Zn (002) in Zn C increased from 15.9 % to 30.4 %. The Zn C symmetric battery exhibited excellent cycling stability and could stably operate for up to 1600 h under a test condition of 5 mA cm −2 /1.25 mAh cm −2 , while the symmetric battery with untreated bare Zn could only stably operate for 84 h. The increase in the proportion of Zn (002) crystal planes significantly enhanced the corrosion resistance of Zn C and effectively suppressed the occurrence of the HER, thereby significantly improving the stability of the anode. In addition, the Zn-C||MnO₂ full battery outperformed the Zn||MnO₂ in terms of specific capacity and capacity retention after cycling. This study proposed a simple and efficient strategy to significantly enhance the stability of the zinc anode by regulating the surface crystal structure composition, providing a new technical path for promoting the practical application of AZIBs.

Zinc (Zn) metal anode has been widely evaluated in aqueous Zn batteries. Nevertheless, the dendrite formation issue and consecutive side reactions severely impede the practical applications of Zn metal at high current densities. Herein, it is reported that engineering the gel electrolyte with multifunctional charged groups by incorporating a zwitterionic gel poly(3-(1-vinyl-3-imidazolio) propanesulfonate) (PVIPS) can effectively address the abovementioned issues. The charged groups of sulfonate and imidazole in the gel electrolyte can texture the Zn 2+ nucleation and deposition plane to (002), which possesses a high activation energy to resist side reactions and induce uniform growth of Zn metal for a dendrite-free structure. In addition, the Zn 2+ solvation structure can be manipulated by the charged groups to further eliminate side reactions for high rate performance Zn batteries. Consequently, the polyzwitterionic gel electrolyte enables a stable cycling with a cumulative capacity of 3000 mA h cm −2 at high density of 7.5 mA cm −2 for the symmetrical Zn battery, and a long-term cycling life for more than 1000 cycles at 5 C of Zn/MnO 2 full battery. It is envisioned that the design of the gel electrolyte will provide promising feasibility on safe, flexible, and wearable energy storage devices.

Aqueous zinc ion batteries (AZIBs) have emerged as a promising energy storage technology due to their high safety and low cost. However, the practical application of AZIBs is severely hindered by unstable Zn anodes especially under high depth of discharge (DOD). This study proposes an in-situ interface alloying engineering based on Ce 3+ additive to regulate Zn deposition behaviors, significantly enhancing the cycling stability and reversibility of Zn anodes. Ce 3+ undergoes in-situ formation of ZnCe alloy on Zn anode interface, inducing preferential deposition of dense Zn (002) plane and effectively mitigating concentration polarization. Zn//Zn symmetric cells with Ce 3+ electrolytes achieve stable cycling for 3000 h at 1 mA cm −2 and deliver a cumulative capacity of 27 Ah cm −2 (5400 h) at a high current density of 5 mA cm −2 . Even under a high DOD of 68.4%, it maintains stable cycling for 420 h. Full cells with a low Negative/Positive capacity (N/P) ratio of 4.30 and high cathode loading of 10 mg cm −2 can stably cycle over 1000 cycles at 2 A g −1 . Furthermore, an 80 mAh-level pouch cell with N/P ratio of 4.68 retains 85% capacity after 100 cycles. This article provides new insights into the interfacial engineering for practical AZIBs.

For practical rechargeable aqueous zinc-ion batteries, the long-term cycling stability of the zinc anode remains significantly constrained by its low utilization efficiency and the persistent challenge of hydrogen evolution . This study demonstrates the fabrication of ultrathin zinc electrodes with a robust Zn (002) texture while ensuring an adequate supply of zinc metal for use as an anode material . This approach effectively suppresses the tendency of zinc atoms to undergo deposition transformation due to dislocation-induced phenomena. Compared to zinc foils with higher deposition amount, the ultrathin Zn anode exhibits enhanced resistance to dendrite growth and interfacial side reactions. Assembled symmetrical cells based on this ultra-thin Zn anode show a cycle life of 1750 h (1 mAcm −2 , 0.5 mAhcm − 2 ), maintaining stable cycling for over 100h even at a high depth of discharge (DOD) of 46.23%. Additionally, the full cell couple with V 10 O 24 exhibits a high initial capacity of 429.6 mAh g −1 and a capacity retention of 75.8% after 1000 cycles.

Aqueous zinc-ion batteries (AZIBs) hold great promise for stationary energy storage, yet their practical deployment is critically impeded by the uncontrolled dendritic growth and parasitic side reactions. Here, we report an interfacial dual-coordination strategy to induce Zn deposition along the Zn(002) facet and suppress the parasitic side reactions. By employing lactic acid (Lac) to pretreat commercial Zn foil, we construct a chemisorbed interface that serves a synergistic “inhibition-guidance” function: the carboxyl group (-COO − ) forms strong bidentate coordination to passivate high-energy Zn (100)/(101) facets, while the hydroxyl group (-OH) establishes a low-energy diffusion pathway on the Zn (002) facet to guide Zn 2+ migration. This intrinsic regulation induces a highly selective Zn (002)-preferred growth, resulting in a dendrite-free lac@Zn anode. Consequently, the lac@Zn symmetric cell achieves a long lifespan of 4900 h (1 mA cm −2 , 1 mAh cm −2 ) and 500 h (5 mA cm −2 , 5 mAh cm −2 , DOD = 37%). Besides, the lac@Zn//MnO 2 full cell delivers exceptional reversibility with 76% capacity retention after 3000 cycles, and a pouch cell presents a high discharge capacity of 0.2 Ah. This work offers a new perspective for developing ultradurable and scalable Zn anodes through precise interfacial engineering.

Zinc-ion batteries (ZIBs) exhibit great potential as energy storage devices due to their low cost and excellent safety. However, the growth of zinc dendrites and hydrogen evolution reaction on the zinc anode severely hinder their industrialization. Here, we modified polyacrylamide (PAM) gel electrolyte with a highly electronegative boron trifluoride diethyl ether complex (BFEE) containing a source of -BF 3 to suppress parasitic side effects on the anode of quasi-solid-state ZIBs. As a Lewis acid, -BF 3 interacts strongly with the interface between anode and electrolyte, where it effectively modulates the inner Helmholtz plane (IHP). Specifically, the electrostatic interaction between -BF 3 group and Zn 2+ ensures uniform Zn 2+ distribution in the PAM/BFEE gel electrolyte, effectively inhibiting the concentration of local electric fields at the interface and suppressing the growth of Zn dendrite. In this work, we have explored the optimal addition amount of BFEE in PAM (2 wt%) and obtained the gel electrolyte of PAM/BFEE-2 %, which exhibits excellent mechanical properties with a fracture stress of 121 kPa and a tensile strain up to 2745 %. Moreover, the modulated IHP promoted the preferential adsorption and growth of Zn 2+ on the Zn (002) crystal plane that with higher adsorption energy in the assembled Zn|PAM/BFEE-2 %|Zn battery. This full battery achieved over 1000 h of cycling stability at a current density of 1 mA cm −2 , confirming that the introduction of highly electronegative BFEE into PAM can effectively suppress dendrite growth and achieve long-term stability of the zinc anode.

The deployment of aqueous zinc metal batteries (AZMBs) is still hindered by unstable interfacial kinetics of Zn metal anodes, resulting in uncontrolled dendrite growth and parasitic side reactions at the Zn/electrolyte interface. Herein, we develop an in situ strategy to construct fluorine-functionalized nanoarrays on a Zn anode with preferential Zn (002) texture exposure (F-Zn) to address these issues. The results demonstrate that the multifunctional Zn anode integrates several key advantages: fluorine functionalization imparts zincophilic characteristics that homogenize Zn 2+ nucleation and stable interfacial kinetics, The nanoarray interface facilitates electrolyte wettability and accelerates interfacial Zn 2+ flux; meanwhile, the dominant Zn (002) crystallographic texture induces uniform Zn deposition and enhances corrosion resistance. As expected, the F-Zn anode exhibits a low nucleation overpotential and enables symmetric cells to operate stably for over 3100 h at 1 mA cm –2 @1 mAh cm –2 and over 1000 h at 4 mA cm –2 @1 mAh cm –2 . Moreover, when coupled with an activated carbon (AC) cathode, the F-Zn||AC delivers exceptional rate capability and maintains approximately 99.2% capacity retention after 10,000 cycles at 4.0 A g –1 . This work presents an effective strategy integrating crystallographic engineering with surface functionalization for high-performance Zn anodes toward advanced AZMBs.
