Symmetric sodium-ion batteries possess promising features such as low cost, easy manufacturing process, and facile recycling post-process, which are suitable for the application of large-scale stationary energy storage. Herein, we proposed a symmetric sodium-ion battery based on dual-electron reactions of a NASICON-structured Na3MnTi(PO4)3 material. The Na3MnTi(PO4)3 electrode can deliver a stable capacity of up to 160 mAh g–1 with a Coulombic efficiency of 97% at 0.1 C by utilizing the redox reactions of Ti3+/4+, Mn2+/3+, and Mn3+/4+. This is the first time to investigate the symmetric sodium-ion full cell using Na3MnTi(PO4)3 as both cathode and anode in the organic electrolyte, demonstrating excellent reversibility and cycling performance with voltage plateaus of about 1.4 and 1.9 V. The full cell exhibits a reversible capacity of 75 mAh g–1 at 0.1 C and an energy density of 52 Wh kg–1. In addition, both ex situ X-ray diffraction (XRD) analysis and first-principles calculations are employed to investigate the sodiation mechanism and structural evolution. The current research provides a feasible strategy for the symmetric sodium-ion batteries to achieve high energy density.

Aqueous zinc-ion batteries (ZIBs) have garnered significant attention due to their high energy, intrinsic safety, and environmental friendliness. NASICON-type compounds are promising cathode candidates in aqueous batteries due to their high ionic conductivity , and high operating voltage. However, these materials, e.g., Na 3 V 2 (PO 4 ) 3 , suffer from inevitable structural degradation and dissolution in aqueous electrolytes, thus hampering their practical performance in aqueous batteries. Interfacial chemistry modulation by electrolyte engineering is beneficial for stabilizing Zn metal anode and high-voltage cathodes in ZIBs . Herein, the interfacial chemistries in an engineered non-concentrated aqueous electrolyte by co-solvent strategy are reported, which synergistically enables high reversibility of Zn anode and long cycling stability of Na 3 V 2 (PO 4 ) 3 cathode. Consequently, the Zn||Na 3 V 2 (PO 4 ) 3 full-cell exhibits high Coulombic efficiency (∼99.3% in average) with a prolonged cycling life, which can be ascribed to the synergistic-effect of the solid-electrolyte interphases with unique organic/inorganic hybrid structures on the electrodes. This work discloses the structures of the interphases formed on the electrodes induced by co-solvent strategy in aqueous electrolytes and their working mechanisms in stabilizing the aqueous Zn batteries, which will guide the future design of advanced aqueous electrolytes with unique interfacial chemistries for batteries.

Sodium super ion conductor (NASICON) structure materials such as Na 3 V 2 (PO 4 ) 3 (NVP) are suitable cathodes for Sodium-ion batteries (SIBs) due to their open three-dimensional structure that can provide fast Na + migration channels. However, low inherent conductivity and capacity restrict the application of NVP. In this paper, NASICON-structured Na 2.25 V 1.25 Ti 0.75 (PO 4 ) 3 @Y (NT 0.75 VP@Y) constructed by yeast with the biological template method is successfully synthesized. Theoretical calculations show that the spherical structure of bio-derived carbon formed after calcination produces a local compressive strain that leads to a uniform distribution of electronic states and stronger adsorption of Na + and NaClO 4 , thus enhancing the electronic and ionic conductivities of the material. NT 0.75 VP@Y exhibits a discharge specific capacity of 135 mAh g −1 at 0.2 C and a capacity retention rate of 94.8 % after 500 cycles. Finally, the full cell and the pouch cell are successfully assembled to verify the practicality of NT 0.75 VP@Y. This paper provides a simple, low-cost, and environmentally friendly way to synthesize high-performance cathode materials for SIBs.

Aqueous Zn-ion batteries (AZIBs) attract intensive attention owing to their environmental friendliness, cost-effectiveness, innate safety, and high specific capacity. However, the practical applications of AZIBs are hindered by several adverse phenomena, including corrosion, Zn dendrites, and hydrogen evolution. Herein, a Zn anode decorated with a 3D porous-structured Na 3 V 2 (PO4) 3 (NVP@Zn) is obtained, where the NVP reconstruct the electrolyte/anode interface. The resulting NVP@Zn anode can provide a large quantity of fast and stable channels, facilitating enhanced Zn ion deposition kinetics and regulating the Zn ions transport process through the ion confinement effect. The NASICON-type NVP protective layer promote the desolvation process due to its nanopore structure, thus effectively avoiding side reactions. Theoretical calculations indicate that the NVP@Zn electrode has a higher Zn ion binding energy and a higher migration barrier, which demonstrates that NVP protective layer can enhance Zn ion deposition kinetics and prevent the unfettered 2D diffusion of Zn ions. Therefore, the results show that NVP@Zn/MnO 2 full cell can maintain a high specific discharge capacity of 168 mAh g −1 and a high-capacity retention rate of 74.6% after cycling. The extraordinary results obtained with this strategy have confirmed the promising applications of NVP in high-performance AZIBs.

A ceramic in polymer hybrid solid electrolyte (HSE) based on a poly vinylidene fluoride-hexafluoropropylene (PVDF-HFP) polymer comprising Na3Zr2Si2PO12 (NASICON) ceramic particles was prepared by a simple solution casting method followed by activation in a liquid electrolyte. The prepared HSE exhibits good flexibility, high ionic conductivity of 2.25 × 10−3 S cm−1 at room temperature (RT), and good interface stability. The carbon coated sodium vanadium phosphate (Na3V2(PO4)3/C) cathode was synthesized by the sol-gel method and assembled into batteries with different electrolytes. The batteries based on HSE exhibit better electrochemical performance than that of NASICON ceramic solid electrolytes, which delivers a reversible capacity of 98 mAh · g−1 at 0.2 C and exhibits good capacity retention of 85% after 175 cycles at 0.5 C. Not only does the HSE inherit great flexibility, but also exhibits good interfacial contact with electrodes. The schematic diagram of Na-ion conductivity in ceramic, polymer and HSE was illustrated to demonstrate the sodium ion transport mechanism. The HSE with high ionic conductivity and good flexibility for interfacial contact with electrodes shall provide a designing strategy for different solid-state batteries.

Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) is a promising candidate as the solid electrolyte in energy storage devices. For practical considerations, the most common ways to ameliorate the low density and high ionic resistance of LATP are usually to use glass additives. In this work, the boron-based (B 2 O 3 , B 2 O 3 -SiO 2 -PbO (BSP), and B 2 O 3 -SiO 2 -K 2 O-Al 2 O 3 (BSKA)) glass are added into LATP by solid method. As the results, the main diffraction peaks of all prepared samples maintain the NASICON-type with the R-3c space group. Meanwhile, the symmetric stretching vibrations of O-P-O bands is redshifted with the addition of boron-based glass, which plays a positive role in bulk conductivity. Additionally, the introduction of boron-based glass additives is effective to increase the grain sizes of the LATP samples. The relative density of the sample is obtained from 93.37% to 95.42%. Furthermore, the total conductivities of 1.33 × 10 −4 , 1.37 × 10 −4 , 1.97 × 10 −4 S cm −1 are obtained in ceramic samples after B 2 O 3 , BSP and BSKA glass additives adding, respectively. The activation energy shows a reduction of 5.26% to 0.36 eV after BSP and BSKA glass adding. Satisfactorily, B 2 O 3 , BSP and BSKA glass have a certain influence on the conductivity, and bear a more favorable argument for the regulation of the morphology and density in the future.

An ion-defective high-entropy NASICON Na3.15V1.525(CrMgAlCuCo)0.095(PO4)3 (HE-CMACC) cathode is ingeniously fabricated by introducing an appropriate amount of Na vacancies and various metal ions. Rate capability and sluggish diffusion kinetics are stimulated by ion defects and high-entropy doping. The HE-CMACC cathode material harvests sustainable long-term cycling durability. The HE-CMACC cathode retains a satisfactory capacity retention of 93.36% after 5000 cycles at 20 C, and it demonstrates excellent high-rate performance within the voltage window of 2–4.2 V (78 mAh g–1 at 40 C). It also exhibits outstanding performance under extreme temperatures (85.76% after 1000 cycles at −20 °C and 87.01% after 850 cycles at 60 °C). Furthermore, in-situ relaxation time distribution (DRT) analysis proved that the high-entropy effect and Na vacancies can enhance electronic conductivity and promote ion diffusion. And in-situ X-ray Diffraction (XRD) results reveal that the fast sodium storage mechanism of HE-CMACC is dominated by solid solution reaction and a small volume strain (∼4.2%) during the process of electrochemical reaction. The full-cell HE-CMACC//HC assembled with hard carbon exhibits a discharge specific capacity of 87.18 mAh g–1 at 20 C and a capacity retention rate of 93.25% after 400 cycles (at 5 C). The strategy of combining high-entropy effects with defect engineering provides important insights into the development of NASICON cathodes.

NIR pc-LEDs develop rapidly due to its spectral tunability and compact design. However, NIR phosphors with both high efficiency and superior thermal quenching resistance are scarce. In this study, a novel NASICON-type structure phosphate NaAlNb(PO 4 ) 3 :Cr 3+ phosphor was synthesized successfully. The crystal structures and the luminescence behaviors were systematically investigated. The phosphor exhibits a broadband NIR emission from 700 to 1100 nm, centered at 808 nm and with a full-width at half maximum (FWHM) of 131 nm. Owing to the high structural rigidity (Θ D = 624.9 K) and wide optical bandgap (E g = 4.1 eV), NaAlNb(PO 4 ) 3 :Cr 3+ shows a high internal quantum efficiency (IQE) of 87% and excellent thermal quenching resistance (retaining 84.19% of its room-temperature intensity at 373 K). A NIR pc-LED was fabricated by combining the as-prepared phosphor with a 460 nm blue LED chip, achieving a high photoelectric conversion efficiency of 18.37% and a strong NIR output power of 50.19 mW at a driving current of 100 mA. All results indicate the NaAlNb(PO 4 ) 3 :Cr 3+ is a promising phosphor for NIR light practical applications.

Na 4 Fe 3 (PO 4 ) 2 (P 2 O 7 ) (NFPP) is a promising cathode material for sodium-ion batteries due to its low cost, high safety, and long cycle life. However, its poor electronic conductivity and air instability hinder practical application, and the issue of air stability has received limited attention. Herein, the hydrolysis behavior of NFPP/C in humid air is systematically investigated. Based on the identified degradation mechanism, a surface reconstruction strategy is proposed via in situ liquid-phase encapsulation of nanostructured Na 3 (VO) 2 PO 4 F (NVPOF). During heat treatment, VO x in NVPOF catalyzes carbon ordering and enables partial V doping into the NFPP surface lattice, thereby modulating surface chemistry, crystal and electronic structure of NFPP. Additionally, the aligned NVPOF/NFPP heterostructure with minimal lattice mismatch forms a built-in electric field, reducing Na⁺ diffusion barriers and interfacial stress. As a result, the Na3 site is activated, leading to significantly enhanced electrochemical performance. The optimized NFPP/NVPOF/C composite delivers excellent rate capability, with a discharge capacity of 126.55 mAh g −1 at 0.1C and 114.40 mAh g −1 at 10C. This work addresses the overlooked air stability issue of NFPP and highlights the importance of surface reconstruction coupled with interface engineering.

NASICON-type solid electrolytes with excellent stability in moisture are promising in all-solid-state batteries and redox flow batteries. However, NASIOCN LiZr2(PO4)3(LZP), which is more stable with lithium metal than the commercial Li1.3Al0.3Ti1.7(PO4)3, exhibits a low Li-ion conductivity of 10−6S cm−1because the fast conducting rhombohedral phase only exists above 50 °C. In this paper, the high-ionic conductive rhombohedral phase is stabilized by Y3+doping at room temperature, and the hot-pressing technique is employed to further improve the density of the pellet. The dense Li1.1Y0.1Zr1.9(PO4)3pellet prepared by hot-pressing shows a high Li-ion conductivity of 9 × 10−5S cm−1, which is two orders of magnitude higher than that of LiZr2(PO4)3. The in-situ formed Li3P layer on the surface of Li1.1Y0.1Zr1.9(PO4)3after contact with the lithium metal increases the wettability of the pellet by the metallic lithium anode. Moreover, the Li1.1Y0.1Zr1.9(PO4)3pellet shows a relatively small interfacial resistance in symmetric Li/Li and all-solid-state Li-metal cells, providing these cells a small overpotential and a long cycling life.Keywords:NASICON;hot pressing;interfacial resistance;Li-ion conductivity;all-solid-state batteries

Sodium-based all-solid-state batteries are considered as promising alternatives to lithium-ion batteries, benefiting from the improved safety and lower cost. However, low ionic conductivity of solid electrolytes as well as poor interfacial contacts among electrodes and solid electrolyte are still the main challenges limiting their practical applications. Herein, a Zn, Mg, and Sc co-doped NASICON-type solid electrolyte Na 3.45 Zr 1.85 (ZnMgSc) 0.05 Si 2.2 P 0.8 O 12 is designed and exhibits a significantly enhanced ionic conductivity of 4.24 mS cm −1 , which is one order of magnitude higher than that of the undoped Na 3 Zr 2 Si 2 PO 12 . Meanwhile, a thin indium tin oxide layer is applied onto the solid electrolyte surface using magnetron sputtering, thereby enhancing stability and wettability at the interface between solid electrolyte and sodium metal anode. This surface treatment strategy significantly raises the critical current density from 0.59 mA cm −2 to 9.95 mA cm −2 while effectively preventing the formation of sodium dendrite. As a result, Na|ITO@Na 3.45 Zr 1.85 (ZnMgSc) 0.05 Si 2.2 P 0.8 O 12 @ITO|Na symmetric battery maintains excellent cycling stability for 1700 h at 60 °C under 6 mA cm −2 , and exhibits stable performance over 2000 h at 2 mA cm −2 under room temperature. In addition, Na 3 V 2 (PO 4 ) 3 |Na 3.45 Zr 1.85 (ZnMgSc) 0.05 Si 2.2 P 0.8 O 12 @ITO|Na battery delivers an initial discharge capacity of 114.6 mAh g −1 with a Coulombic efficiency of 96.36 % at 0.1C and maintains 89.2 % capacity after 1000 cycles at 2C-rate.
