The natural abundance of sodium has fostered the development of sodium-ion batteries for large-scale energy storage. However, the low capacity of the anodes hinders their future application. Herein, carbon-encapsulated MnSe-FeSe nanorods (MnSe-FeSe@C) have been fabricated by the in-situ transformation from polydopamine-coated MnO(OH)-Fe 2 O 3 . The heterostructure constructed by MnSe and FeSe nanocrystals induces the formation of built-in electric fields, accelerating electron transfer and ion diffusion, thereby improving reaction kinetics. In addition, carbon enclosure can buffer the volumetric stress and enhance the electrical conductivity. These aspects cooperatively endow the anode with superior cycling stability and distinguished rate performance. Specifically, the discharge capacity of MnSe-FeSe@C reaches 414.3 mA h g −1 at 0.1 A g −1 and 388.8 mA h g −1 even at a high current density of 5.0 A g −1 . In addition, it still retains a high reversible capacity of 449.2 mA h g −1 after 700 long cycles at 1.0 A g −1 . Further, the ab initio calculation has been employed to authenticate the existence of the built-in electric field by Bader charge, indicating that 0.24 electrons in MnSe were transferred to FeSe. The in-situ XRD has been used to evaluate the phase transition during the charging/discharging process, revealing the sodium ion storage mechanism. The construction of heterostructure material paves a new way to design performance-enhanced anode materials for sodium-ion batteries.

Development of an efficient air cathode for metal–air batteries composed of an element that is abundant on earth is a scientific and technical challenge. Here, nitrogen (N)-doped carbon cathodes were prepared using two conventional doping methods, namely ammonia activation (ammoxidation) and introduction of an N-containing precursor. Interestingly, the introduction of N-containing precursors to prepare the N-doped carbon material not only gave a different pore distribution with increased surface area but also maintained considerable N content, unlike the use of the ammoxidation method – thus greatly enhancing the catalytic activity (low overpotential) and improving the discharge capacity (6905 mA h g−1) and cycle life (from 8 to 66 cycles) in sodium–oxygen batteries compared with the pure carbon material. This study also stresses the importance of adopting the optimized synthesis method to prepare the N-doped carbon cathode.

Constructing robust 2D−based energy storage nanomaterials by well−defined pore architectures and rational surface modification are critical yet daunting challenges for rechargeable alkali−ion batteries. Herein, a new−type 2D interwoven multi pores decorated Co 3 O 4 @N−doped carbon nanosheet with rich surface defects is proposed as lithium/sodium ion anodes for the first time. The combining experimental researches, microscopic structure characterization and dynamics analysis demonstrate that the multi porous structure provides large numbers of channels to accelerate Li + /Na + transport, rational surface design creates abundant active sites for fast ions reactions, while robust carbon shell offers excellent ionic/electrical conductivity and structural integrity. The obtained bifunctional composites deliver superior rate performance and long−term cycle stability (~529 mA h g −1 after 2000 cycles in LIBs and ~166 mA h g −1 after 1700 cycles in SIBs) due to the synergistic contribution of the unique structure and surface defects . Furthermore, it still remains a high reversible capacity (>610 mA h g −1 after 1000 cycles) in full cell. Kinetic analysis reveals the designed anode exhibits prominent pseudocapacitive behavior, enabling ultra−fast lithium/sodium storage and ultrahigh−rate capability. This work offers valuable insights for developing high performance energy storage devices.

We report for the first time a Na-ion battery anode material composed of P-doped CoSe 2 nanoparticles (P-CoSe 2 ) with the size of 5–20 nm that are uniformly embed in a 3D porous honeycomb-like carbon network. High rate capability and cycling stability are achieved simultaneously. The honeycomb-like carbon network is rationally designed to support high electrical conductivity, rapid Na-ion diffusion as well as the accommodation of the volume expansion from the active P-CoSe 2 nanoparticles. In particular, heteroatom P-doping within CoSe 2 introduces stronger P-Co bonds and additional P-Se bonds that significantly improve the structure stability of P-CoSe 2 for highly stable sodiation/desodiation over long-term cycling. P-doping also improves the electrical conductivity of the CoSe 2 nanoparticles, leading to highly elevated electrochemical kinetics to deliver high specific capacities at high current densities. Benefiting from the unique nanostructure and atomic-level P-doping, the P-CoSe 2 (2:1)/C anode delivers an excellent cycle stability with a specific capacity of 206.9 mA h g −1 achieved at 2000 mA g −1 after 1000 cycles. In addition, this material can be synthesized using a facile pyrolysis and selenization/phosphorization approach. This study provides new opportunities of heteroatom doping as an effective method to improve the cycling stability of Na-ion anode materials.

Up to now, three kinds of ion-storage mechanisms are summarized towards anode materials in lithium/sodium-ion batteries, but they have low capacity and poor cyclic performance. Therefore, it is necessary to develop a new approach to optimize ion storage. Herein, we report an adsorption/desorption storage route through engineering electronic structure of cation-deficient Ti 1-x O 2 nanosheets. Ti 1-x O 2 nanosheets indeed exhibit higher capacity (332.1 mA h g −1 vs. 137.7 mA h g −1 for LIBs, 195.7 mA h g −1 vs. 111 mA h g −1 for SIBs), and more stable cyclic performance (296 mA h g −1 vs. 99 mA h g −1 for LIBs, 178.1 mA h g −1 vs. 80.2 mA h g −1 for SIBs after 100 cycles) at 0.1 A g −1 than TiO 2 nanosheets. Kinetics analysis and density functional theory (DFT) calculations reveal that electronic structures of vacancy within Ti 1-x O 2 nanosheets encourage a novel adsorption–desorption storage route. These results highlight the benefits of the engineered electronic structures within electrode material and implement novel ion-storage mechanism towards broad energy storage applications.

P2-Na0.6Li0.11Fe0.27−xMn0.62YxO2 (x = 0, 0.5%, 1%, and 2%) cathode materials were successfully prepared using a traditional solid-state method with ball milling-assisted modification. The effect of Y-doping on the crystal structure, grain size, morphology and sodium storage performance of Na0.6Li0.11Fe0.27Mn0.62O2 was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), galvanostatic charge–discharge cycling tests, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results demonstrated that the ball-milling pre-treatment method could effectively reduce the grain size and mitigate the aggregation of Na0.6Li0.11Fe0.27Mn0.62O2. Additionally, reasonable Y-doping (x = 1%) significantly enhances the rate capability and cycling stability of Na0.6Li0.11Fe0.27Mn0.62O2via improving the Na+ diffusion kinetics and the reversibility of the oxygen redox reaction. These results indicate that Na0.6Li0.11Fe0.26Mn0.62Y0.01O2 is a promising candidate material for high-rate and long-life cathodes for Na-ion battery application.

We succeed in obtaining Mo 2 C embedded in S-doped carbon (Mo 2 C/SC) nanofibers by electrospinning and sulfuration. The use of S-doped carbon not only provides more additional Na + storage active sites to enhance its sodium storage performance, but also increases electrons migration and ions diffusion. As the anodes for sodium ion batteries (SIBs), the electrode exhibits excellent rate capacities of 242 and 96 mA h g −1 from 0.1 A g −1 to 5 A g −1 . Excitingly, the high-rate performance is superior, achieving 102.7 mA h g −1 at 5 A g −1 over 1000th cycle. This project provides ideas for the development the high-rate and long-term stable of the Mo 2 C in energy storage devices.

Na3LuB8O15, the first sodium lutetium borate in the Na–Lu–B–O system, was prepared by the spontaneous crystallization method. Na3LuB8O15 is crystallized in the centrosymmetric triclinic space group P1¯ with the following cell parameters: a = 6.4047(12)Å, b = 7.3342(13)Å, c = 13.081(2)Å, α = 88.999(7)°, β = 78.631(8)°, γ = 66.622(7)°, and Z = 2. The general configuration of Na3LuB8O15 can be characterized as a network structure created by infrequent multiboron anion chain skeletons [B8O17] and [LuO7] polyhedra shared by oxygen atoms, where Na ions are filled in the pores to balance charges. According to a UV–vis-NIR spectrum investigation, the chemical has a short ultraviolet cutoff edge (185 nm). Thermal analysis reveals incongruent melting compound properties. In addition, a first-principles calculation was conducted to delve deeper into the correlation between the performance and the structure.

Metal–air batteries are important power sources for electronics and vehicles because of their remarkable high theoretical energy density and low cost. In this work, we firstly investigate the electrochemical properties of sodium air batteries (SABs) with the addition of ferrocene in the electrolyte. Combining charge–discharge measurements with field-emission transmission electron microscopy images of the discharged air cathodes, our results have demonstrated that two different pathways with ferrocene as an electrocatalyst and involved in the electrochemistry during the charge process might be governed by the morphological features of the electrode caused by the deposition of Na2O2 in SABs. The SAB with ferrocene as a catalyst exhibits a high cycling performance of up to 230 cycles with a high capacity of 1000 mA h g−1.

Flexible aqueous zinc-based batteries (ZBs) are promising for wearable electronics but are hindered by low operating voltage and poor cycling stability. While zinc hexacyanoferrate (ZnHCF) represents a promising cathode candidate, its practical application is limited by rapid capacity decay. This failure is conventionally attributed to irreversible structural collapse. Herein, our findings depart from the prevailing view by demonstrating that degraded cathodes retain their structural integrity and recover capacity in specific media. We identify the primary failure mechanism as Zn 2+ entrapment induced by strong electrostatic interactions, distinct from lattice dissolution. Leveraging this insight, a dual-regulation strategy is proposed utilizing Na + co-intercalation to mitigate ion trapping and a quasi-solid composite hydrogel to suppress water activity. Consequently, a high full-cell voltage (1.8 V) Zn//ZnHCF battery is developed delivering exceptional stability over 4000 cycles. This work not only revises the fundamental understanding of ZnHCF degradation but also provides a robust pathway for high-performance aqueous energy storage. Graphical Departing from the prevailing view that ZnHCF degradation arises from irreversible structural collapse, this work identifies Zn 2+ entrapment induced by strong electrostatic interactions as the primary failure mechanism. By introducing Na + co-intercalation to mitigate ion trapping, ZnHCF reversibility is markedly enhanced, enabling a flexible 1.8 V Zn//ZnHCF battery with exceptional cycling stability supported by a quasi-solid composite hydrogel.

The efficient extraction of lithium from high Na/Li ratio brines remains a critical challenge for sustainable resource utilization. This study develops a trioctyl phosphate (TOP)-dibenzoylmethane (DBM)-kerosene synergistic extraction system guided by density functional theory (DFT) calculations, which reveal complementary electrostatic interactions between the enol oxygen of DBM and the P O group of TOP, facilitating the formation of stable coordination sites for Li + . Under optimized conditions, the system achieves a single-stage lithium extraction efficiency of 97%. Furthermore, an innovative CO 2 -based stripping process eliminates the need for conventional acids by in situ generation of H + via the reaction of CO 2 with H 2 O forms carbonic acid, enabling simultaneous lithium stripping and direct precipitation of Li 2 CO 3 . The integrated process demonstrates high efficiency under ambient conditions, achieving >99% stripping within 4 min and concentrating lithium over 10-fold. The resulting Li 2 CO 3 product exhibits high purity (>99.9%) and well-defined crystallinity, suitable for battery applications. The system maintained excellent stability over ten extraction-washing-stripping cycles with consistent performance. This work offers a green and efficient strategy for lithium recovery from challenging brine sources, combining theoretical molecular design with sustainable process engineering.

Temporal modulation of upconversion luminescence (UCL) has attracted considerable interest. However, rise-edge-based tuning strategy is often hampered by severe luminescence quenching, underscoring the need for rational design strategies that simultaneously optimize temporal dynamics and absolute UCL output. Herein, by introducing Na + ions as charge compensators, we overcame the low solubility of Yb 3+ in the SrMoO 4 host lattice and achieve a quenching concentration of up to 20 mol%, far exceeding typical levels in aliovalent doping systems. Coupled with the concomitant lattice distortion, this strategy enhances the excitation energy absorption of Yb 3+ , the energy transfer efficiency from Yb 3+ to Ho 3+ , and the radiative transition rate of Ho 3+ . The green and red UCL intensities exhibit enhancements of >3000-fold and >2000-fold, respectively, yielding a high upconversion quantum yield (UCQY) of 4.11 % and excellent temporal color tunability. These findings provide valuable insights for developing UCL materials capable of efficient dynamic luminescence control.
