The loose and randomly oriented byproduct (i.e., Zn4(OH)6SO4·xH2O, ZHS) in situ formed on the zinc (Zn) surface is recognized to be the primary cause for dendritic Zn growth and side reactions. Switching the detrimental passivation film into a dense and kinetically favorable solid electrolyte interphase (SEI) is a straightforward strategy to tackle these issues faced by Zn metal anodes but remains largely unexplored. Herein, a new polymer film directly grown on Zn metal through room-temperature plasma-enhanced chemical vapor deposition is proposed to induce the lateral growth of ZHS nanosheets and decrease the Zn2+ desolvation barrier, thereby forming a beneficial composite SEI for suppressing Zn dendrite growth and surface corrosion. As a result of the joint effect, we realize an impressively stable cycling behavior in symmetric cell over 3400 h at 2 mA cm–2. Moreover, full cells also demonstrate prolonged lifespans. This work opens a new avenue for stabilizing Zn metal batteries by turning detrimental ZHS into a favorable interlayer.

Sulfide solid-state electrolytes have garnered considerable attention owing to their notable ionic conductivity and mechanical properties. However, achieving an electrolyte characterized by both high ionic conductivity and a stable interface between the electrode and electrolyte remains challenging, impeding its widespread application. In this work, we present a novel sulfide solid-state electrolyte, Li3.04P0.96Zn0.04S3.92F0.08, prepared through a solid-phase reaction, and explore its usage in all-solid-state lithium sulfur batteries (ASSLSBs). The findings reveal that the Zn, F co-doped solid-state electrolyte exhibits an ionic conductivity of 1.23 × 10–3 S cm–1 and a low activation energy (Ea) of 9.8 kJ mol–1 at room temperature, illustrating the aliovalent co-doping’s facilitation of Li-ion migration. Furthermore, benefiting from the formation of a LiF-rich interfacial layer between the electrolyte and the Li metal anode, the Li/Li3.04P0.96Zn0.04S3.92F0.08/Li symmetrical cell exhibits critical current densities (CCDs) of up to 1 mA cm–2 and maintains excellent cycling stability. Finally, the assembled ASSLSBs exhibit an initial discharge capacity of 1295.7 mAh g–1 at a rate of 0.05 C and at room temperature. The cell maintains a capacity retention of 70.5% for more than 600 cycles at a high rate of 2 C, representing a substantial improvement compared to the cell with Li3PS4. This work provides a new idea for the design of solid-state electrolytes and ASSLSBs.

A new three-layered film was fabricated on magnesium (Mg) alloy via electroplating to guard against corrosion in a chloride aqueous environment, which consisted of an underlying double-layered zinc/copper (Zn/Cu) and a top aluminum–zirconium (Al–Zr) layer. The Zn/Cu underlayers not only impeded the galvanic corrosion between the Al–Zr coating and Mg alloy but also improved the adhesive ability between the substrate and the upper Al–Zr layer. Herein, we discussed the nucleus sizes of Al–Zr coatings at the stage of nucleation carried out with different contents of ZrCl4 in AlCl3–1-butyl-3-methylimidazolium chloride ionic liquid. The sandwichlike three-layered Zn/Cu/Al–Zr coatings were systematically investigated by surface morphology, phase structure, hardness, anticorrosion performances, and first-principles calculations. The corrosion current density declined from 1.461 × 10–3 A·cm–2 of bare Mg to 4.140 × 10–7 A·cm–2 of the Zn/Cu/Al–Zr3 sample. Neutral salt spray testing demonstrated that the Zn/Cu/Al–Zr3 sample showed no evident signs of corrosion after 6 days of exposure. The enhancement of the corrosion protection property was related to the fact that the application of the Cu layer changed the corrosion direction from initial longitudinal corrosion to extended lateral corrosion and the top Al–Zr coating hindered the transmission of aggressive ions. In addition, upon increasing the Zr content in the alloy films, the Fermi energy reduced initially and then increased. The Al–Zr3 alloy with 8.3 atom % Zr showed the lowest Fermi energy (−3.0823 eV), which exhibited the most efficient corrosion protection. These results showed that the prepared three-layered coating provided reliable corrosion protection to Mg alloy and may thus promote its practical applications.

With the aim of obtaining high corrosion resistant Zn–Sn alloy coatings from an ionic liquid, the effects of electrodeposition potential and electrolyte composition on the electrodeposition behavior, film composition, morphology and corrosion performance were investigated. Cyclic voltammograms indicate that Zn and Sn were co-deposited at distinct reduction potentials as pure Zn and Sn elements. In addition, the phase composition analysis also showed that the obtained Zn–Sn alloy deposits (8 wt.%–45 wt.% Zn) consist of a two-phase mechanical mixture of small aggregates of Zn and Sn metals. The Zn content of the alloy significantly increases as the electrodeposition potential and electrolyte Zn (II)/Sn (II) ratio increase. The corrosion performance study of the obtained Zn–Sn coatings showed that they have a passivation behavior and their corrosion resistance increases as the alloy-Sn content increases. To improve their morphological properties, ethylene diamine tetraacetic acid additive was introduced into the electrolyte and greatly improved the morphology and corrosion resistance of the deposits. For the first time, it was shown that high corrosion resistance Zn–Sn coatings can be obtained from ionic liquids. Copyright © 2014 John Wiley & Sons, Ltd.

Aqueous Zn–S batteries (AZSBs) have garnered increasing attention in the energy storage field owing to their high capacity, energy density , and cost effectiveness. Nevertheless, sulfur (S) cathodes face challenges, primarily stemming from sluggish reaction kinetics and the formation of an irreversible byproduct (SO 4 2− ) during the charge, hindering the progress of AZSBs. Herein, Te–S bonds within S-based cathodes were introduced to enhance electron and ion transport and facilitate the conversion reaction from zinc sulfide (ZnS) to S. This was achieved by constructing heteroatomic TeS-x@Ketjen black composite cathodes (HM-TeS-x@KB, where x = 36, 9, and 4). The HM-TeS-9@KB electrode exhibits long-term cycling stability, maintaining a capacity decay rate of 0.1 % per cycle over 450 cycles at a current density of 10 A g −1 . Crucially, through a combination of experimental data analysis and theoretical calculations, the impact mechanism of Te on the charge and discharge of S active materials within the HM-TeS-9@KB cathode in AZSBs was investigated. The presence of Te–S bonds boost the intrinsic conductivity and wettability of the HM-TeS-9@KB cathode. Furthermore, during the charge, the interaction of preferentially oxidized Te with S atoms within ZnS promotes the oxidation reaction from ZnS to S and suppresses the irreversible side reaction between ZnS and H 2 O. These findings indicate that the heteroatomization of chalcogen S molecules represents a promising approach for enhancing the electrochemical performance of S cathodes in AZSBs.

The currently leading oxygen reduction reaction (ORR) catalysts are non-precious metal electrocatalysts. However, porous structure engineering and accessibility of Fe–N–C sites still remain a huge challenge. Here, we developed hierarchically porous Fe–N–C catalysts for cathodes of Zn–air batteries using a gas diffusion strategy, which has dense active Fe–Nx moieties. The Fe-NCNF-120 catalyst provided high kinetic current density and mass activity towards the ORR, as well as a more positive initial potential and half-wave potential (Eonset = 1.00 V, E1/2 = 0.90 V). According to experiments, the outstanding ORR activity can be attributed to the organized micro- and mesoporous structure, enhanced intrinsic activity of dense and accessible active sites Fe–Nx, and the facilitated mass and electron transport by 3D interconnected pores. As the cathode for Zn–air batteries, Fe-NCNF-120 demonstrated high power density, a high open-circuit voltage, and excellent stability. The combination of inherent activity with dense and accessible spots in this work opens up new possibilities for the design and synthesis of effective electrocatalysts for energy storage and conversion.

Fe–N–C single-atom catalysts are considered among the most promising non-precious metal-based catalysts for oxygen reduction reaction (ORR), but issues such as low utilization of active sites and the easy aggregation of single atoms severely hinder their application in fuel cells and metal–air batteries. Herein, a single-atom Fe-embedded hierarchical porous hollow carbon fiber catalyst (Fe SAC/HCNF) is reported for ORR. The hollow channels and the porous structure of the fibers facilitate the exposure of single-atom active sites, and offer multidimensional mass transfer pathways to promote the transport of reactants, thus significantly enhancing catalytic performance. Additionally, the abundant micropores exert spatial confinement, which is beneficial for preventing the aggregation of single atoms. Leveraging its unique structural advantages, the Fe SAC/HCNF catalyst demonstrates outstanding ORR activity with low metal loading, boasting a high half-wave potential of 0.905 V, a substantial double-layer capacitance ( C dl ) of 41.1 mF cm −2 , and a notable kinetic current density of 45.2 mA cm −2 in alkaline media. Furthermore, the liquid Zn–air battery (ZAB) using Fe SAC/HCNF catalyst as the air cathode exhibits excellent battery performance and long-term cycling durability nearly 600 h. And the flexible quasi-solid-state ZAB can be stably cycled in various flat/bent states, which is promising for applications in flexible electronic devices. Graphical

Cu 2 MoS 4 became a novel active alternative material to noble metal co-catalysts, which can effectively promote photocatalytic hydrogen evolution. To investigate the effect of Cu 2 MoS 4 on the photocatalytic performance of Zn-VIA compounds, ZnO, ZnS, ZnSe, and ZnTe were composited with Cu 2 MoS 4 to construct the photocatalysts, and we analyzed the four catalysts for the crystal structure, microscopic morphology, photoelectronic properties, and hydrogen evolution performance. Comparing the four different photocatalysts, the composite of ZnSe and Cu 2 MoS 4 has the highest photocatalytic hydrogen evolution efficiency, and the hydrogen evolution rate of the optimal ratio of ZSeC-20 reaches about 2617 μmol/g/h, which is about 46 times higher than that of pure ZnSe. It is attributed to the loading of Cu 2 MoS 4 to build a heterogeneous structure, which reduces the photogenerated electron and hole recombination rate, which enhances the photocatalytic water splitting hydrogen evolution rate.

Non-precious metal catalysts with efficient bifunctional catalytic performance are urgently needed in rechargeable Zn-air battery. Herein, a 3D N-doped double-walled hollow carbon spheres/nanotube CoNi alloy hybrid (CoNi-NC/DLHCs) was rationally constructed by the optimized Stöber method combined with the epitaxial attachment MOF strategy. Take advantage of effectively utilized the active site of 3D open architecture, accelerated intermediate transport, and the large specific surface area ( S BET ), CoNi alloys exerted maximum oxygen reduction reaction (ORR) activity and oxygen evolution reaction (OER) activity. The as-prepared CoNi-NC/DLHCs catalyst manifests a higher half-wave potential of 0.85 V and Tafel slop of 88 mV dec -1 for ORR, as well as satisfied OER activity with Tafel slope of 92 mV dec -1 and overpotential at 10 mA cm -2 of 275 mV. A liquid zinc-air battery equips with CoNi-NC/DLHCs achieved a satisfying open circuit potential (OCP) of 1.51 V, a maximum peak power density of 183.4 mW cm -2 , and a cycle endurance stability of more than 700 h. This research highlights good prospects in designing oxygen electrocatalysts catalysts in the metal-air battery field.

Bimetallic zeolitic imidazolate framework materials (Zn/Co-ZIFs) represent a notable class within the field of metal–organic frameworks (MOFs). These materials are characterized by their advantageous properties typical of MOFs, including a high specific surface area and tunable pore sizes, in addition to exhibiting the structural stability that is characteristic of zeolites. In contrast, although tin-based materials demonstrate a high theoretical specific capacity, they experience significant volume changes during the charge and discharge cycles of batteries, leading to materal degradation and reduced cycling stability. In this study, Sn doping was successfully achieved in Zn/Co-NPC (N-doped porous carbon) by thermally treating Zn/Co-ZIFs at 700℃ through an impregnation method. This doping enhanced the sodium storage capacity of Zn/Co-NPC and improved its electrochemical performance. Experimental data indicate that the Sn/Zn/Co-NPC composite has a specific surface area of 332.80 m 2 g −1 and an average pore diameter of 7.30 nm. When this composite is used as the anode material in sodium-ion batteries, it demonstrates outstanding performance: after 100 cycles, its reversible specific capacity reaches 344.20 mAh g −1 (at a current density of 100 mA g −1 ) and exhibits excellent rate capability. Consequently, this study provides substantial insight into the prospective advancement of structurally stable and high-capacity anode materials for sodium-ion batteries.

Aqueous Zn–I 2 batteries have garnered significant attention due to their high abundance and safety. However, the sluggish iodine redox kinetics and undesirable shuttle effect severely hindered their wider application. Herein, dual doping of B and N provides an effective strategy to modulates chemical properties and electron distributions of carbon hosts, resulting in high performance of Zn–I 2 batteries. The local electron redistribution enhances electron density at the Fermi level of the carbon host, thereby improving intrinsic conductivity. Additionally, combining experiments and DFT calculations reveal that N B center sites are benefited in suppressing shuttle effects, strengthened interactions with iodide species, and facilitated catalytic conversion kinetics. Notably, Zn–I 2 batteries fabricated with B and N co-doped porous carbon (BNAC) achieve an outstanding capacity (231.7 mAh g −1 at 0.1 A g −1 ) and excellent cycling stability (capacitance retention of 98 % after 4,500 cycles). This study not only provides valuable insights into the design of advanced carbon materials but also clarifies the active sites in B/N co-doped carbon materials, offering guidance for the rational design of carbon-based electrode materials for Zn–I 2 batteries.

The lack of suitable cathode materials with a high capacity and good stability is a crucial problem affecting the development of aqueous Zn-ion batteries. Herein, a novel strategy for the modification of V2CTx through molten salt thermal treatment is proposed. In the novel route, S heteroatoms were introduced into V2CTx through a substitution reaction during the dissolution of Li2S in LiCl–KCl molten salts. Then, surface V2O5 was obtained through the in situ electrochemical charging/discharging of the S-doped V2CTx (MS-S-V2CTx) cathode. The assembled Zn/MS-S-V2CTx battery showed a high reversible discharge capacity of 411.3 mAh g–1 at a current density of 0.5 A g–1, an 80% capacitance retention after long cycle stability tests at 10 A g–1 for 3000 cycles, and a high energy density of 375.5 Wh kg–1 in 2M ZnSO4. Density functional theory calculations demonstrate that the improved electrochemical performance of the cathode can be attributed to the introduced S heteroatoms, which considerably reduced the ion diffusion energy barrier for Zn2+ ions and improved the stability of V2O5. This work provides a novel method to produce highly active and stable vanadium-based cathodes for aqueous Zn-ion batteries.
