Nevertheless, several critical challenges persist, predominantly the propensity for dendrite growth, inherent kinetic limitations, deleterious electrode side reactions, and perplexing shuttle effects, which collectively impede the practical implementation and commercial viability of ZBBs. In this context, fibers fabricated via electrospinning technology exhibit remarkable advantages in terms of enhanced specific surface area, improved electrical conductivity, and superior mechanical integrity, while also affording optimized pore structures. These unique features render electrospinning fibers particularly promising for addressing the key issues that limit ZBBs performance, including energy density, charge/discharge rate capabilities, and cycling stability. So, it is very necessary to summarize electrospinning technology application in ZBBs. This paper firstly analyzes the fundamental mechanisms and inherent challenges of ZBBs including zinc-ion, zinc-air, and zinc-halide batteries. Subsequently, the application of electrospinning fiber structures in anodes, cathodes, separators, and electrolytes optimization for ZBBs is summarized. Finally, the prospect of electrospinning technology in ZBBs is envisioned, and existing challenges are presented for its further application.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 10","pages":"6924 - 6951"},"PeriodicalIF":11.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve its hydrogen storage performance, a nanohydrogen storage alloy was innovatively combined with Mg(NH₂)₂–2LiH, AB5 type nanohydrogen storage alloy LaNi₅ was prepared by co-precipitation method. Nano LaNi₅ and single-walled carbon nanotubes (SWCNTs) were co-doped into the Mg(NH₂)₂–2LiH system at a ratio of 10 wt% and 2 wt%, significantly enhancing the hydrogen storage performance of Mg(NH₂)₂–2LiH. The initial hydrogen ab/desorption temperatures of the co-doped system decreased from 110/130 °C to 45/85 °C. The release of by-product ammonia is significantly inhibited. 4.73 wt% H₂ can be ab/desorption in 150 min at 180/170 °C. Cycle tests show that the co-doped system can still maintain a hydrogen storage capacity of 4.75 wt% after ten hydrogen release cycles. Mechanism and density functional theory study have shown that during the hydrogen release process, partially hydrogenated LaNi₅ weakens the chemical bonding in Mg(NH₂)₂, promoted the dissociation of hydrogen from the Mg(NH₂)₂–2LiH system, while playing a dual role of \"hydrogen overflow\" and \"hydrogen pump\". SWCNTs act as auxiliary agents, helping to refine particle size and increase thermal conductivity. The synergistic effect of the two optimizes the comprehensive hydrogen storage performance of Mg(NH₂)₂–2LiH.

In this study, we demonstrate the first successful synthesis of single-phase HECs based on Mo and W systems through an innovative high-entropy design strategy. Guided by comprehensive thermodynamic predictions, the single-phase solid solution formation temperatures were determined for the HEC-<i>n</i> (<i>n</i> = 2–9) series of high-entropy carbides. We achieved the configurational-entropy driven formation of HEC nanoparticles containing 4–9 transition metal elements via an ultra-fast joule heating process (i.e., (TiZrHfVNbTaCrWMo)C). Through rapid synthesis and screening, we obtained (VNbCrWMo)C nanoparticles exhibiting the best HER activities and exceptional long-term stability over 168 h due to high-entropy composition design and synthesis strategies, outperforming unary, binary, ternary, quaternary carbides and carbides with more than six metallic elements. Theoretical calculations and X-ray photoelectron spectroscopy analysis reveal that the (VNbCrWMo)C high-entropy carbide achieves enhanced HER activity through multi-metallic synergy, where constituent elements cooperatively redistribute electron density at catalytic sites.

This electrode achieved an extraordinary specific capacitance of 2838.8 F g⁻¹ at a current density of 1 A g⁻¹, with 70.3% retention at 30 A g⁻¹ and 86.1% retention after 6,000 cycles at 15 A g⁻¹, demonstrating its remarkable performance and durability.

To enhance its photocatalytic antimicrobial properties, polymeric carbon nitride (PCN) was incorporated into the Ce-OFDC matrix, forming a Ce-OFDC/PCN composite material. Antibacterial assays demonstrated that Ce-OFDC/PCN had significant inhibitory effects on both <i>Escherichia coli</i> (<i>E. coli</i>) and <i>Staphylococcus aureus</i> (<i>S. aureus</i>), achieving inhibition rates of 99.5% and 94.3%, respectively. Notably, the antibacterial performance of Ce-OFDC/PCN was superior to that of Ce-OFDC or PCN alone. Furthermore, photocurrent and electrical impedance scanning measurements demonstrated that the Ce-OFDC/PCN composites showed improved photocurrent response and superior efficiency in separating photogenerated electrons and holes. The photocurrent density of Ce-OFDC/PCN reached 120 μA cm⁻², which was 1.5 times higher than that of PCN (80 μA cm⁻²) and 12 times higher than that of Ce-OFDC (10 μA cm⁻²). Electron paramagnetic resonance analysis indicated that reactive oxygen species played a crucial role in the antimicrobial process, with superoxide radicals (·O₂⁻) and hydroxyl radical (·OH) showing the most prominent influence. We conducted reactive oxygen species (ROS) scavenging experiments to further confirm this view. After adding glutathione (GSH) to remove all ROS, the antibacterial efficiency of Ce-OFDC/PCN decreased by about 40%. Adding D-mannitol to remove ·OH reduced the inhibition rate to 54.7%, and adding superoxide dismutase (SOD) to remove ·O₂⁻ reduced the inhibition rate to 65.4%. The Ce-OFDC/PCN heterostructure increased the separation efficiency of photogenerated electrons and holes, producing increased reactive oxygen species. That, in turn, contributed to the observed superior photocatalytic antibacterial performance.
