Interfacial pH fluctuation is one of the primary reasons for issues related to Zn metal anodes. Herein, polar amphoteric alanine, as a multifunctional electrolyte additive, is designed to regulate the electric double layer (EDL) and solvation structure. Alanine with self-adaptation capability to pH can stabilize electrolyte pH. Due to more negative adsorption energy, alanine preferentially adsorbs on the Zn surface and repels water molecules within the EDL. Alanine-enriched EDL effectively shields the surface tips, homogenizes interfacial electric field distribution, and promotes preferential deposition of horizontal flaky Zn. Alanine-enriched EDL limits the contact between water and the Zn anode. Alanine additive decreases the quantity of water molecules in the Zn 2+ solvation sheath and disrupts H-bond networks in the electrolyte. Consequently, a dense and textured Zn deposition is achieved. Corrosion and side reactions are suppressed. Cycling stability of symmetrical cells attains 2700 h at 3 mA cm −2 /1 mAh cm −2 and 2050 h at 5 mA cm −2 /1 mAh cm −2 . Average coulombic efficiency reaches 99.8% over 4500 cycles at 5 mA cm −2 /1 mAh cm −2 . Even within KOH alkaline electrolytes, alanine additive still improves the cycling lifespan of symmetrical cells to 100 h at 0.5 mA cm −2 /0.5 mAh cm −2 .

The practical applications of aqueous zinc-ion batteries (AZIBs) are hindered by detrimental effects such as dendrites formation at the Zn metal anode interface and parasitic side reactions induced by H2O. Hence, we propose adding amide additives to the Zn sulfate electrolyte (ZSO) to regulate the composition and properties of the electrolytes, thereby stabilizing the Zn anode interface. Different amide molecules containing formamide (FA), acetamide (AA), or trifluoroacetamide (TFA) are discussed. The polar C═O group shared by amide molecules can interact with Zn2+, forming their solvation shells. The molecules can also facilitate the transport of Zn2+ and increase the conductivity of the electrolytes. Additionally, amide molecules can interact with H2O through hydrogen bonds to limit the erosion of active H2O on the Zn anode. The unique –H, −CH3, and −CF3 groups of the molecules result in different polarities and varying numbers of interaction sites with H2O and Zn2+, leading to some differences in the protective effects of the Zn anode. The stability and lifespan of Zn||Zn batteries assembled with amide electrolytes have significantly improved, especially those with TFA. Moreover, the Zn||NH4V4O10 full cells demonstrate remarkable capacity retention, and the overall performance of the batteries has also been enhanced.

The hydrazine oxidation reaction (HzOR) plays a critical role in direct hydrazine fuel cells and presents a promising alternative to the kinetics-sluggish oxygen evolution reaction in water reduction. Engineering catalysts with high-density multifold nanotwin structures has emerged as a compelling strategy to enhance catalytic activity. However, the exploration of multifold nanotwins for HzOR applications remains absent. Herein, we report the successful synthesis of a porous Ni-Zn-Cu catalyst featuring high-density twofold and fivefold nanotwins. The Ni-Zn-Cu catalyst supported on Ni foam (Ni-Zn-Cu/Ni foam) exhibits exceptionally high catalytic activity and stability toward the HzOR, achieving a current density of 204.3 mA cm −2 at 0.0 V vs. RHE and retaining up to 89.1 % after 20 h of continuous electrolysis. Online mass spectrometer (MS) analysis indicates that the Ni-Zn-Cu coating facilitates N N bond cleavage of N 2 H 4 . This study offers valuable insights into the development of multifold nanotwin catalysts for advancing HzOR applications.

Explosive progress in wireless and functional mobile electronics calls for miniaturized energy-storage units to push forward energy-autonomous and self-sustainable intelligent microsystems. Emerging three-dimensional (3D) microstructured electrodes for energy-storage devices have drawn great attention due to their attractive stereoscopic architectures to increase the areal loading of active materials. Here, we report a strategy for fabricating a 3D helical electrode for a zinc microbattery (Zn MB) by combining a “top-down” lithography technique and a “bottom-up” electrochemical depositing process. Thanks to the available stereoscopic space, the achieved 3D helical electrode shows a high surface area, outstanding electrolyte permeation, and stress adaptive capability. Based on the structural advantages of a 3D helical electrode, high-performance rechargeable Zn MB has been achieved by depositing Zn and NiOOH as anode and cathode materials, respectively. The Zn microbattery demonstrates a specific areal capacity up to 0.325 mAh·cm–2 corresponding to a high energy density of 0.55 mWh·cm–2. It also exhibits remarkable rate capability (0.272 mAh·cm–2 at 100 mA·cm–2) and excellent cycling stability (85% retention after 1000 cycles). The outstanding electrochemical performance indicates that the 3D Zn MB can work as a promising power source for advanced electronic devices. Paired micro-/nanofabrication process for battery electrodes is also of great significance in gearing toward carbon-neutral.

Aqueous Zn-ion batteries have gradually become a suitable choice for large-scale energy storage systems owing to their safety and lower cost. However, Zn metal anodes typically suffer from uneven electrodeposition and zinc dendrite formation, which restricts Zn-ion batteries from being used in further applications. To mitigate this problem, a simple and quick chemical surface modification is employed to construct a multifunctional hybrid interface consisting of ZnF 2 and Sn on the surface of the Zn metal anode. ZnF 2 show a low diffusion energy barrier for Zn 2+ , effectively shield the direct corrosive reaction from the aqueous electrolyte , and simultaneously increase the hydrogen evolution potential of the Zn electrode. Furthermore, the Sn particles provide a large number of nucleation sites and charge centers, avoiding the direct growth of dendrites. The interface-modified Zn anode achieve stable cycles of 700 h and 500 h at high current densities of 5 and 10 mA/cm 2 , respectively, while the assembled Zn@ZnF 2 –Sn||V 2 O 5 full battery achieve over 400 stable cycles at 1 A/g. This work uncover the internal mechanism of inhibiting Zn dendrites by the multifunctional interface, providing a means for stabilizing the Zn anode under practical conditions.

P2-Na 0.67 Ni 0.33 Mn 0.67 O 2 (NNMO) is promising cathode material for sodium-ion batteries (SIBs) due to its high specific capacity and fast Na + diffusion rate. Nonetheless, the irreversible P2-O2 phase transformation, Na + /vacancy ordering, and transition metal (TM) dissolution seriously damage its cycling stability and restrict its commercialization process. Herein, Na occupation manipulation and interface stabilization are proposed to strengthen the phase structure of NNMO by synergistic Zn/Ti co-doping and introducing lithium difluorophosp (LiPO 2 F 2 ) film-forming electrolyte additive . The Zn/Ti co-doping regulates the occupancy ratio of Na e /Na f at Na sites and disorganizes the Na + /vacancy ordering, resulting in a faster Na + diffusion kinetics and reversible P2-Z phase transition for P2-Na 0.67 Ni 0.28 Zn 0.05 Mn 0.62 Ti 0.05 O 2 (NNZMTO). Meanwhile, the LiPO 2 F 2 additive can form homogeneous and ultrathin cathode-electrolyte interphase (CEI) on NNZMTO surface, which can stabilize the NNZMTO-electrolyte interface to prevent TM dissolution, surface structure transformation, and micro-crack generation. Combination studies of in situ and ex situ characterizations and theoretical calculations were used to elucidate the storage mechanism of NNZMTO with LiPO 2 F 2 additive. As a result, the NNZMTO displays outstanding capacity retention of 94.44% after 500 cycles at 1C with 0.3 wt% LiPO 2 F 2 , excellent rate performance of 92.5 mA h g −1 at 8C with 0.1 wt% LiPO 2 F 2 , and remarkable full cell capability. This work highlights the important role of manipulating Na occupation and constructing protective film in the design of layered materials, which provides a promising direction for developing high-performance cathodes for SIBs.

Aqueous zinc metal batteries (ZMBs) have emerged as a promising alternative to lithium-ion batteries, owing to their high theoretical capacity, low redox potential, and intrinsic safety. However, the Zn anode suffers from three interrelated critical issues (Zn dendrite growth, the hydrogen evolution reaction (HER), and corrosion reaction), which collectively impede the practical application of ZMBs. Herein, we focus on addressing HER and corrosion reaction via electrolyte modification to boost the overall performance of ZMBs. Pyrrolidone carboxylic acid (PCA), a natural moisturizing factor (NMF), was introduced as an additive into the ZnSO 4 electrolyte, with two synergistic functions: (1) forming stronger hydrogen bonds with H 2 O molecules that reduce water activity to suppress HER; and (2) dissociating and creating an acidic environment that eliminates the corrosion products Zn 4 SO 4 (OH) 6 · x H 2 O and its analogs (collectively referred to as ZSH) to mitigate corrosion reaction. Benefiting from these effects, the Zn||Zn symmetric cell maintained stable cycling for 5000 h at 1 mA cm –2 and 1 mAh cm –2 (only 220 h without PCA), the Zn||Cu asymmetric cell exhibited a high coulombic efficiency of 99.66% at 1 mA cm –2 (only 98.30% without PCA), and the Zn||V 2 O 5 full cell still delivered a high discharge capacity of 116.3 mAh g –1 at 1200th cycle at 5 A g –1 (only 69.7 mAh g –1 without PCA). This work provides a facile and eco-friendly strategy for constructing highly reversible Zn anodes and high-performance ZMBs.

Aqueous zinc (Zn) metal batteries (AZMBs) are a promising candidate for large-scale energy storage, but the issues of Zn anodes involving nonuniform Zn plating/stripping, H2 evolution, and low Zn utilization rate (ZUR) in aqueous electrolytes hinder their practical application. Herein, we report an in situ colloidal electrolyte via SO42–-polycation electrostatic interaction to circumvent these challenges. Mechanistic studies reveal that the polycation-confined SO42– diffusion significantly elevates the Zn2+ transference number to 0.82, which can suppress anion-induced side reactions and minimize interfacial concentration gradients. Moreover, the polycations can form dynamic adsorption on Zn, disrupt the water’s original H-bond network, and create an H2O-poor electrical double layer, which homogenizes the electric field distribution and suppresses H2 evolution on Zn. Consequently, the optimized electrolyte (Colloid-6) enables highly compact and (100)-plane-oriented Zn electrodeposits and uniform Zn stripping behavior even at 25 mAh cm–2, corresponding to 85.4% ZUR. The Zn electrodes in Colloid-6 achieve a long-term cycling life over 4200 h under 2 mAh cm–2, deep-cycling stability over 300 h under 25 mAh cm–2, and high-temperature adaptability (80 °C). Moreover, Colloid-6 with low water reactivity can inhibit the vanadium oxide cathode dissolution, thus supporting the stable operation of Zn//V2O5·nH2O full batteries under harsh conditions.

Materials engineering plays a pivotal role in determining the energy storage efficiency of supercapacitors. In this work, a Zn-MnO₂/MoS₂ heterostructure was synthesized via a hydrothermal route, where the synergistic coupling of Zn-doped MnO₂ with conductive MoS₂ nanosheets significantly enhanced redox activity, electronic conductivity, surface area, and structural stability. Zn doping not only expanded the MnO₂ lattice to facilitate faster ion diffusion but also induced oxygen vacancies, providing additional active sites for charge storage. Meanwhile, MoS₂ offered a conductive 2D framework that buffered volume changes and accelerated electron transport. As a result, the Zn-MnO₂/MoS₂ electrode delivered a high capacitance of 1440 F g⁻¹ at 2.85 A g⁻¹, outperforming individual Zn-MnO₂ (1250 F g⁻¹) and MoS₂ (210 F g⁻¹) as well as previously reported electrodes in 1 M KOH. Furthermore, the assembled Zn-MnO₂/MoS₂//AC device exhibited a specific capacitance of 147 F g⁻¹ at 2.85 A g⁻¹, an excellent energy density of 59 Wh kg⁻¹ at a power density of 1145 W kg⁻¹, and outstanding cycling stability with ~91% retention over 14,000 cycles. These experimental and theoretical insights highlight the strong potential of Zn-MnO₂/MoS₂ heterostructures for next-generation practical supercapacitor applications.

The electrochemical nitrate reduction reaction (NO 3 RR) represents an attractive and sustainable strategy for simultaneously addressing nitrate contamination and producing value-added ammonia under ambient conditions. Compared with the energy- and carbon-intensive Haber-Bosch process, NO 3 RR offers a decentralized pathway for green ammonia synthesis powered by renewable electricity. However, achieving high ammonia selectivity remains challenging because nitrate-to-ammonia conversion involves a multistep proton-coupled electron transfer cascade, in which the initial two-electron reduction of nitrate to nitrite and the subsequent hydrogenation of nitrite-derived intermediates must proceed in a kinetically coordinated manner. In practice, this cascade is often hindered by reactivity mismatch between the upstream and downstream steps, resulting in nitrite accumulation, incomplete hydrogenation of NO x intermediates, and intensified competition from the hydrogen evolution reaction. Despite the conceptual promise of tandem catalysis, a practical framework for quantifying and optimizing such kinetic matching remains insufficiently developed. Here, we report a layered double hydroxide-derived Cu-Zn dual-site electrocatalyst in which the Cu/Zn ratio is used as a compositional lever to regulate cascade coordination during NO 3 RR in neutral electrolyte. Among the investigated compositions, Cu 1.5 Zn 1.5 Al-R exhibits the optimal balance between nitrate activation and subsequent hydrogenation, delivering a peak Faradaic efficiency of 95% for ammonia at −0.7 V vs. RHE, together with a high ammonia yield of 1526.0 mmol·g −1 ·h −1 . Time-dependent product analysis further shows that this optimal catalyst displays suppressed nitrite accumulation together with rapid ammonia formation, indicating an effective kinetic coupling between the consecutive reduction steps. Mechanistic studies based on online differential electrochemical mass spectrometry and in situ infrared spectroscopy reveal that the reaction mainly proceeds through a *NOH-mediated pathway. The results suggest that Cu-rich motifs are responsible for promoting nitrate adsorption and the initial two-electron reduction step, while Zn-associated motifs regulate the local hydrogenation microenvironment and facilitate the further hydrogenation of nitrite-derived intermediates near adjacent Cu sites. As a result, the Cu/Zn ratio serves as a key compositional parameter to balance the tandem reaction kinetics and improve ammonia selectivity. This work demonstrates that ratio-programmed Cu-Zn tandem catalysis is an effective strategy to enhance nitrate-to-ammonia conversion by kinetically matching the sequential elementary steps. The present study not only provides a viable catalyst design principle for selective NO 3 RR, but also offers useful insight into the regulation of multistep electrocatalytic reactions through compositional engineering.

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.

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.
