As a novel lead-free perovskite derivative material, zero-dimensional Cs3Cu2I5 crystals exhibit remarkable optical properties and hold great application prospects in the field of radiation detection. To further enhance the scintillation performance and detection efficiency, we fabricated high-quality, centimeter-level Cs3Cu2I5:Na+ single crystals using a low-cost anti-solvent method. Na+ doping in the Cs3Cu2I5 lattice optimizes the photoluminescence quantum yield (PLQY) to 95%, which can be attributed to enhanced exciton–phonon coupling and boosted self-trapped exciton fraction. Compared to the intrinsic crystal, the energy resolution and light yield of Cs3Cu2I5:5%Na+ under 137Cs γ-rays are improved by 22% and 10.5%, respectively. Under X-ray excitation, Cs3Cu2I5:5%Na+ crystals exhibit stronger RL intensity, faster response speed, lower afterglow and lower detection limit. Based on excellent X-ray detection capability, a breakthrough spatial resolution of 25.6 LP per mm@MTF = 0.2 is achieved for the Cs3Cu2I5:5%Na+@PMMA flexible film. Cs3Cu2I5:Na+ crystals boast superior optical performance, exceptional detection capabilities, cost-effectiveness and eco-friendliness, rendering them a highly competitive candidate for high-resolution γ-ray detection and flexible X-ray imaging.

Sodium-sulfur (Na-S) batteries are believed as the hopeful energy storage and conversion techniques owing to the high specific capacity and low cost. Nevertheless, unstable sodium (Na) deposition/stripping of Na metal anode, low intrinsic conductivity of sulfur cathode, and severe shuttling effect of sodium polysulfides (NaPSs) pose significant challenges in the actual reversible capacity and cycle life of Na-S batteries. Herein, a self-supporting electrode made of nitrogen-doped carbon fiber embedded with cobalt nanoparticles (Co/NC-CF) is designed to load sulfur. Meanwhile, gel polymer electrolyte (GPE) with high ion transfer ability is obtained by in-situ polymerization inside the battery. During the polymerization process, an integrated electrode-electrolyte and a continuous ion-electron conduction network in a composite cathode are constructed inside the Na-S battery. It is noteworthy that the designed GPE demonstrates superior ionic conductivity and effective adsorption of NaPSs that can significantly suppress the shuttle effect. Leveraging the synergistic interplay between the designed GPE and self-supporting cathode, the assembled quasi-solid-state (QSS) Na-S battery exhibits great cycling stability. These experimental results are further corroborated by COMSOL Multiphysics simulations and density functional theory (DFT) calculations, which mechanistically validate the enhanced electrochemical performance. The findings of this study offer new and promising perspectives for advancing the development of next-generation solid-state batteries.

Electronic modulation of Pt sites is of great significance in catalytic reaction involved chemical engineering process. Alkali metal doping is a promising strategy to modify the d orbit of Pt, which can effectively affect the reaction between material and adsorbates, however, the relationship is still unclear. Here, we have rationally designed Pt-modified Na-doped WO 3 nanorods, and the electronic modulation of Pt can be finely modified by Na doping. The Pt-Na/WO 3 -Ar nanorods exhibit excellent H₂S sensing performance, with high response (R a /R g = 701 @ 1 ppm), low operating temperature (110 °C), and detection limit as low as 2.42 ppb. Experimental and theoretical results indicate that the introducing of Na effectively enhances the interaction between Pt nanoparticles (NPs) and WO 3 . Additionally, Na doping successfully modulate the d-band center of Pt, optimizing the adsorption and desorption processes during sensing. The synergistic effects of these components enable the Pt-Na/WO 3 -Ar sensor to exhibit outstanding H₂S sensing performance. Notably, the fabricated sensors are further used to monitor the hydrogen sulfide (H 2 S) of halitosis biomarkers, which holds significant application potential in environmental protection and medical diagnostics.

Employing appropriate single-atom (SA) catalysts in room-temperature sodium-sulfur (Na-S) batteries is propitious to promote the performance, whereas a universal designing strategy for the highly-efficient single-atom catalysts is absent. In this work, we adopt natural language processing techniques to screen the potential single-atom catalysts, then a binary descriptor is constructed to optimize the catalyst candidates. Atomically dispersed cobalt anchored to both nitrogen and sulfur atoms (SA Co-N/S) is selected as an ideal catalyst to significantly facilitate sulfur reduction reaction. The sulfur cathode catalyzed with SA Co-N/S almost realizes complete transformation, and the corresponding pouch cell exhibits satisfactory performance with high mass loading. In-situ X-ray absorption spectroscopy reveals the dynamical interactions between SA Co-N/S and sulfur species in the sulfur reduction reaction. Our work provides a method to select the preferable SA catalyst and to understand the interfacial catalysis dynamics in the sustainable Na-S systems.

Hard carbon (HC) is the most promising anode material for sodium-ion batteries (SIBs), nevertheless, the understanding of sodium storage mechanism in HC is very limited. As an important aspect of storage mechanism, the steady state of sodium stored in HC has not been revealed clearly to date. Herein, the formation mechanism of quasi-metallic sodium and the quasi-ionic bond between sodium and carbon within the electrochemical reaction on the basis of theoretical calculations are disclosed. The presence of quasi-metallic sodium is further confirmed with the assistance of a specific reaction between the sodiated HC electrode and ethanol, by analyzing the reaction products with Fourier-transform infrared spectroscopy, gas chromatography, and nuclear magnetic resonance. Moreover, based on the specific chemical reaction, the composition of fully sodiated HC is estimated to be NaC 6.7 , and the corresponding capacity of sucrose-derived HC is calculated to be 333.4 mAh g −1 in SIBs, matching well with the experimental result. This work helps to reveal the steady state of sodium and improve the understanding of sodium storage behavior in HC from the aspect of charge transfer. In addition, the proposed method is also expected to pave the way to investigate sodium storage mechanisms in other electrode systems.

Na-ion batteries (NIBs) are emerging as a promising alternative to Li-ion batteries (LIBs). To align with sustainability principles, the design of electrode materials must incorporate considerations for abundant and environmentally friendly elements, such as redox-active Fe. Despite its appeal, the enduring challenge of Fe migration in layered cathodes remains inadequately addressed over decades. Here, we propose a “seat-squatting” strategy via Li-substitution to fundamentally suppress Fe migration. Li is strategically introduced to migrate first, occupying available migration sites without inducing structural damage and effectively raising the activation energy for Fe migration. Experimental and theoretical validation using O3-Na0.83Li0.17Fe0.33Mn0.5O2 (NaLFM) demonstrates a robust suppression of irreversible Fe migration. As a result, the NaLFM cathode delivers enhanced structural and electrochemical cycling stability. This work illustrates a compelling strategy to curb irreversible Fe migration in NIBs, offering a pathway for the development of stable and cost-effective layered oxides based on Fe redox centers.

Liquid metal batteries (LMBs) with Na anode exhibit the advantages of low-cost, high-safety, long-lifespan, and easy scale-up, making them promising for large-scale energy storage applications. However, the high solubility of Na and its sluggish kinetics in discharge products result in severe self-discharge and low cathode utilization, significantly hindering the development of Na-based LMBs. In this study, a stable Na-Li dual cation LMB with metal Sb cathode is designed based on the in-situ displacement reaction between Na and molten salts of lithium halides electrolyte. This design effectively suppresses the self-discharge of the battery, and the multistage discharge mechanism of the dual-cation system enhances cathode utilization. Moreover, the self-healing property of the Sb cathode protects the electrode against volume expansion and degradation, enhancing cycling performance. The Na-Li| LiCl-KCl-NaCl |Sb cell was constructed and operated at 485 °C. The battery retained 97.02 % of its capacity after 800 cycles at 0.6 C, with a decay rate of 0.00373 % per cycle. Furthermore, the battery achieves a cathode material utilization of 89 % at 0.6 C. These improvements effectively promote the development and application of LMBs.

Tin (Sn) has been recognized as a viable anode material for sodium-ion batteries due to its non-toxic nature, affordability, and high specific capacity. Nonetheless, Sn experiences substantial volume changes during charge–discharge processes, which results in accelerated capacity degradation. Herein, a novel solvothermal method is developed to synthesize a composite of tin nanoparticles covalently bonded to nitrogen-doped three-dimensional graphene (Sn/3DNG) through stable C-Sn bonds. The design of the Sn/3DNG composite effectively mitigates the volume changes of tin during sodium insertion/extraction process by using the robust framework of 3DNG to confine and support Sn nanoparticles. The presence of C-Sn bonds prevents the tin nanoparticles from clumping together, thereby enhancing the electrode’s durability. Owing to these improvements, the Sn/3DNG anode exhibits a cyclic retention of 87.7 % after 800 cycles and maintains a substantial specific capacity of 350 mAh g -1 at 5 A g -1 . This advancement underscores the potential of Sn-based nanocomposites in advancing the next generation of rechargeable batteries.

The stable phase equilibrium of the reciprocal quaternary system of Na+, K+//VO3–, Cl––H2O at 298.15 K was investigated by an isothermal solution equilibrium method. The equilibrium liquid phase solubility data and physical property data [density (ρ), refractive index (nD), and pH] were determined, and the composition of the equilibrium solid phase was verified by X-ray diffraction. The phase diagram and physical property–composition diagrams were constructed based on the equilibrium solubility data and physical property data. The phase diagram contains three invariant points, seven isothermal univariant curves, and five crystalline phase regions. The study found that this quaternary system belongs to a complex system with the presence of the double salts. By comparing the experimental results with literature data, it was confirmed that at 298.15 K, the chemical formulas of the complex salt which formed by the quaternary system Na+, K+//VO3–, Cl––H2O were consistent with the complex salt chemical formula (Na2mKn(VO3)2m+n) proposed by the Druzynski group, thus verifying the reliability of this experiment. The results of this study will provide new experimental data for the thermodynamics of vanadium–water systems.

Layered vanadium oxides have been considered as highly promising cathode materials for aqueous zinc-ion batteries (ZIBs) due to their unique open crystal structure and high theoretical specific capacity. However, the structural instability and sluggish Zn2+ diffusion kinetics limit their further application in ZIBs. Here, a novel and stable cathode (porous Na-V2O5) for aqueous ZIBs is rationally constructed by using a straightforward MOF-assisted synthetic method. The Na-V2O5 exhibits remarkable capacity of 306 mAh g−1 at 0.1 A g−1, exceptional rate characteristics (264.3 mAh g−1 at 2.0 A g−1), and great cycling capabilities over 1000 cycles with a capacity-retention of 83.4% when examined as a cathode for ZIBs. Higher pseudo-capacitance, quicker charge-transfer/ion-diffusion kinetics, and a robust architecture have been attained in the Na-V2O5 cathode, which are in charge of the superior zinc-ion storage performance. This has been made possible by the pre-intercalated Na+ cations and the resulting layer structure. Additionally, the Zn2+ and H+ co-intercalation/extraction-based energy storage method has been validated. This research may help rationally design layer-structured V2O5 cathodes for high energy and power density aqueous energy storage systems.

Nickel particles with different contents of Ni 3 S 2 surface layer were prepared for their application as cathode materials in Na/NiCl 2 batteries . The surface modification of nickel particles is found to prevent their growth and battery degradation during cycling. The optimum level of surface modification was determined by electrochemical tests and morphology characterization. Excessive Ni 3 S 2 layer seems to cause particle aggregation resulting in low reversible capacity. The capacity of the cell with optimum level of Ni 3 S 2 surface modification layer after 50 cycles is about 4 times greater than that without Ni 3 S 2 surface modification layer.

Vanadium hexacyanoferrate (VHCF) with an open-framework crystal structure is a promising cathode material for rechargeable aqueous metal-ion batteries owing to its high electrochemical performance and easy synthesis. In this paper, vanadium hexacyanoferrate cathodes were first used for constructing rechargeable aqueous sodium-ion batteries (VHCF/WO3) and tested in the new-type electrolyte (NaP-4.6) consisting of a polyethylene glycol (PEG)/H2O/NaClO4 electrolyte with a low H+ concentration (molar ratio of [H2O]/[Na+] is 4.6), which has high stability at a high current density as high as 1000 mA g–1 with a capacity retention of 90.3% after 2000 cycles at high coulombic efficiency (above 97.8%). To understand their outstanding performance, the proton-assisted sodium-ion storage mechanism and interphase chemistry of VHCF are investigated by solid-state NMR (ssNMR) technology. It is suggested that the H+ storage reaction is accompanied by the redox of vanadium atoms and Na+ intercalation is accompanied by the redox of iron atoms. It is also observed that the complex of polyethylene glycol (PEG) with Na+ (PEG–Na+) exists on the VHCF surface, which facilitates the stability of VHCF and promotes the alkali-ion transfer at a high current density. The results of the ssNMR study offer new insights into the intercalation chemistry of Prussian blue analogues with open-framework-structured compounds, which can greatly broaden our horizons for battery research.
