NASICON-structured solid-state electrolytes (SSEs) are highly promising materials for sodium solid-state metal batteries (NaSMBs). However, the current synthesis methods are often labor-intensive and inefficient, consuming a significant amount of energy and time. Here, an ultrafast high-temperature synthesis (UHS) technique is successfully demonstrated to directly synthesize NASICON-type SSEs from mixed precursor powders, reducing the synthesis time from hours to merely seconds. The intermediate with a Na 3 PO 4 structure plays a critical role in the rapid synthesis of NASICON-type SSEs, ultimately leading to the formation of the final NASICON phase. Moreover, the UHS-synthesizes NASICON-type Na 3.3 Zr 1.7 Lu 0.3 Si 2 PO 12 (NZLSP) exhibits high room temperature ionic conductivity of 7.7 × 10 −4 S cm −1 , approximately three times that of the undoped Na 3 Zr 2 Si 2 PO 12 (NZSP). The Na|NZLSP|Na symmetric cell can sustain highly stable cycling for over 4800 h. This study provides a novel insight and validation in the precise and targeted synthesis of complex oxide solid-state electrolytes.

The low ionic conductivity of solid-state electrolytes (SSEs) and the inferior interfacial reliability between SSEs and solid-state electrodes are two urgent challenges hindering the application of solid-state sodium batteries (SSSBs). Herein, sodium (Na) super ionic conductor (NASICON)-type SSEs with a nominal composition of Na 3+2 x Zr 2– x Mg x Si 2 PO 12 were synthesized using a facile two-step solid-state method, among which Na 3.3 Zr 1.85 Mg 0.15 Si 2 PO 12 ( x = 0.15, NZSP-Mg 0.15 ) showed the highest ionic conductivity of 3.54 mS∙cm −1 at 25 °C. By means of a thorough investigation, it was verified that the composition of the grain boundary plays a crucial role in determining the total ionic conductivity of NASICON. Furthermore, due to a lack of examination in the literature regarding whether NASICON can provide enough anodic electrochemical stability to enable high-voltage SSSBs, we first adopted a high-voltage Na 3 (VOPO 4 ) 2 F (NVOPF) cathode to verify its compatibility with the optimized NZSP-Mg 0.15 SSE. By comparing the electrochemical performance of cells with different configurations (low-voltage cathode vs high-voltage cathode, liquid electrolytes vs SSEs), along with an X-ray photoelectron spectroscopy evaluation of the after-cycled NZSP-Mg 0.15 , it was demonstrated that the NASICON SSEs are not stable enough under high voltage, suggesting the importance of investigating the interface between the NASICON SSEs and high-voltage cathodes. Furthermore, by coating NZSP-Mg 0.15 NASICON powder onto a polyethylene (PE) separator (PE@NASICON), a 2.42 A∙h non-aqueous Na-ion cell of carbon|PE@NASICON|NaNi 2/9 Cu 1/9 Fe 1/3 Mn 1/3 O 2 was found to deliver an excellent cycling performance with an 88% capacity retention after 2000 cycles, thereby demonstrating the high reliability of SSEs with NASICON-coated separator.

Sodium super-ionic conductors (NASICON)-type electrolyte Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 (LATP), with high ionic conductivity and low cost, is considered as one of the most attractive alternatives to liquid electrolytes . However, the poor interfacial compatibilities of LATP electrolyte in lithium batteries lead to the failure, which hinders its further development. Herein, a MoS 2 coating layer as an artificial solid electrolyte interphase (ASEI) is used for modifying the surface of LATP (MCLATP) via an economical and uncomplicated spin coating method, which not only effectively inhibits the decomposition of LATP, but also in-situ forms a conversion layer consisting of Li 2 S and Mo metal during cycling. The conversion layer can improve the interfacial charge transfer kinetics and decrease the charge transfer resistance . According to interfacial modification of MoS 2 , the symmetric cells show slight polarization, and the Li/MCLATP/LFP cells demonstrate excellent cycling performance over 300 cycles at 1 C. The enhanced batteries performance is ascribed to interfacial modification of MoS 2 as an ASEI layer, which reduces interfacial concentration polarization caused by the formed microcracks around the surface during decomposition of LATP. This work provides a promising strategy to construct the interface between Li metal and solid-state electrolytes for other unstable electrolytes beyond NASICON .

A lithium-ion conductor with microporous channels (p-LATP) was prepared by using templates from a hydrothermal-assisted sol-gel method, and the as-prepared p-LATP was infiltrated to obtain p-LATP and d-LATPs composites in this work. SEM photos showed that the morphologies of p-LATP, d-LATP, and p-LATP and d-LATP composites were quite similar. XRD analysis showed that the crystallographic structures were also similar. TEM examinations revealed that microporous channels existed in the pure p-LATP and the p-LATP and d-LATP composites but not in the pure d-LATP. The total conductivities of the composites were higher than those of the pure p-LATP and pure d-LATP. The enhancement of the total conductivity of the composites was ascribed to the interaction of microporous channels and dense lithium-ion conducting areas. The promising results obtained in this work provide a new way to prepare solid lithium-ion conductors.

Using stable inorganic solid electrolyte to replace organic liquid electrolyte could significantly reduce potential safety risks of rechargeable batteries. Na-superionic conductor (NASICON)-structured solid electrolyte is one of the most promising sodium solid electrolytes and can be employed in solid-state sodium batteries. In this work, a NASICON-structured solid electrolyte Na 3.1 Zr 1.95 Mg 0.05 Si 2 PO 12 was synthesized through a facile solid-state reaction, yielding high sodium-ionic conductivity of 1.33 × 10 −3 S·cm −1 at room temperature. The results indicate that Mg 2+ is a suitable and economical substitution ion to replace Zr 4+ , and this synthesis route can be scaled up for powder preparation with low cost. In addition to electrolyte material preparation, solid-state batteries with Na 3.1 Zr 1.95 Mg 0.05 Si 2 PO 12 as electrolyte were assembled. A specific capacity of 57.9 mAh·g −1 is maintained after 100 cycles under a current density of 0.5C rate at room temperature. The favorable cycling performance of the solid-state battery suggests that Na 3.1 Zr 1.95 Mg 0.05 Si 2 PO 12 is an ideal electrolyte candidate for solid-state sodium batteries.

Na superionic conductor ( NASICON)-structured Na 4 MnCr(PO 4 ) 3 (NMCP) possessing unique three-electron transfer process renders admirable energy density for sodium ion batteries (SIBs). However, the current issues like its sluggish Na + diffusion kinetics, deficient intrinsic conductivity, and unsatisfactory structural stability, hinder its practical application. Herein, a selective replacement of O elements in PO 4 group by Cl anions in the NMCP system was developed to significantly enhance its electrochemical performance. The results affirm that the enhanced performance of Cl doped samples can be attributed to the enlargement of cell size, the creation of Na vacancies and the weakness of Na2 O bond after Cl doping. The as-prepared Na 3.85 □ 0.15 MnCr(PO 3.95 Cl 0.05 ) 3 /C (NMCPC − 15/C) cathode delivers a high capacity (128.0 mAh/g at 50 mA g −1 ) and excellent rate performance (73.0 mAh/g at 1000 mA g −1 ) in contrast to NMCP/C that merely provides 105.2 mAh/g at 50 mA g −1 and reduces to 47.4 mAh/g at 1000 mA g −1 . Meanwhile, NMCPC − 15/C shows a capacity retention of 60.7 % at 1000 mA g −1 after 500 cycles, while only 37.1 % for NMCP/C in the same test conditions. Moreover, the satisfactory performance and energy density of NMCPC − 15/C||hard carbon (HC) full cell confirm the potential practicality of NMCPC − 15. Therefore, chloride ions doping into NMCP has practical application prospects in the preparation of high-performance cathode materials and our work also offers new inspiration to apply anion doping strategies in promoting the performance of the other NASICON-structured cathodes for SIBs.

Lithium-air/oxygen battery has raised widespread interest due to its extraordinary theoretical energy density (up to 3500 Wh kg −1 ). In this study, a flexible free-standing NASICON (Na-super ionic conductor)-type hybrid solid-state polymer electrolyte (HSPE) based on PVDF-HFP (poly(vinylidene fluoride-hexafluoropropylene)) copolymer and NASICON LATP (Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 ) was prepared and investigated. The HSPE membranes exhibited an ionic conductivity of 1.02 × 10 −4 S cm −1 at room temperature along with a electrochemical window from 2 to 4.5 V. Using the HSPE, a lithium-oxygen/air battery with an inorganic solid-state cathode was fabricated. High initial discharge capacities of 4654 and 5564.3 mAh g −1 were reached under pure O 2 and ambient air, respectively. Compared to conventional porous polypropylene (PP) separator, the HSPE membrane alleviated the corrosion of the lithium anode, thus improving the cyclability of the cells. The results presented in this study suggest the great potential application of NASICON-type HSPE membrane in solid-state rechargeable lithium-air/oxygen batteries.

Sodium super-ionic conductor (NASICON) materials are believed as competitive cathodes for sodium-ion batteries, however, their practical application is still prohibited by the limited reversible capacity. In this study, the tri-metal NASICON structured Na 3 Mn 0.5 V 0.5 Ti(PO 4 ) 3 is designed to combine with reduced graphene oxide (NMVTP/rGO) as cathode material . Benefited from the multi-step redox couples of Mn, V, and Ti, NMVTP/rGO realizes high reversible capacity and wide operating voltage. The small sizes of Na 3 Mn 0.5 V 0.5 Ti(PO 4 ) 3 and rGO ensure the fast charge migration. The rGO inhibits the dissolution of electrode material. As a result, NMVTP/rGO exhibits large specific capacity of 284.6 mAh g −1 at 0.1C, high rate performance (170.2 mAh g −1 at 1C and 108.5 mAh g −1 at 5C), and good cyclic stability. This work demonstrates a new insight for designing tri-metal NASICON structured materials with high capacity for sodium-ion batteries.

Direct conversion of methanol and acetic acid (HAc) into acrylic acid (AA) and methyl acrylate (MA) is remarkably significant for the high-value utilization of coal-based chemicals. However, the previous catalysts, due to their single function or poor synergy between multiple active sites, remain large challenges in direct synthesis of acrylic acid. Herein, we designed a novel catalyst system through coating TiO 2 to sodium superionic conductor (NASICON) substrate for direct synthesis of acrylic acid from methanol and acetic acid. It was revealed that the catalyst with TiO 2 coating showed obviously improved performance. The selectivity of AA+MA highly reached 56.1 % at 380 °C, corresponding to the spatiotemporal yield of 46.5 μmol·g −1 ·min −1 . It was demonstrated that TiO 2 coating catalyzes the oxidative dehydrogenation of methanol to formaldehyde, while NASICON substrate exerts important effects on the aldol condensation of formaldehyde and acetic acid, and their effective synergy promotes the direct synthesis of acrylic acid.

NASICON Na3V2(PO4)3 was investigated as cathode material in hybrid ion batteries using Li as counter and LiPF6 as electrolyte. The highly efficient and homogeneous heating merits of microwave irradiation facilitates the Na3V2(PO4)3 achieving excellent crystal structure, uniform carbon coating, as well as ideal particle size. After microwave irradiation, a specific capacity of 96.5 mAh g−1 is obtained for the first intercalation of lithium ion into Na3V2(PO4)3 at 0.1 C rate. For long-term cycling stability, the capacity retention reaches 84.4% at 5 C rate after 500 cycles. The unique intercalation/extraction characteristic promises Na3V2(PO4)3 an ideal candidate material for next-generation hybrid ion storage system.

The integration of Mn in Na4Mn1.5Fe1.5(PO4)2P2O7 (NMFPP) enhances the energy density but compromises the Na+ mobility and structural stability due to limited electron hopping and pronounced Jahn–Teller effects. To address this, a structurally compatible anionic substitution strategy is implemented by partially replacing PO43– with bulkier and less electronegative SiO44– groups. The reinforced cathode exhibits enhanced rate performance, which is attributed to lattice expansion induced by the larger SiO44– units, thereby facilitating Na+ diffusion and reducing impedance during charge–discharge processes, as supported by GITT and DRT analyses. In addition, the improved cycling stability results from the lower electronegativity of Si, which enables SiO44– to accommodate local charge redistribution without triggering structural collapse, as evidenced by reduced lattice volume fluctuations observed in in situ XRD. Consequently, Na4Mn1.5Fe1.5(PO4)1.95(SiO4)0.05P2O7 achieves a capacity retention of up to 85.42% for 500 cycles at 1 C and 80.54% over 1500 cycles at 5 C. These findings highlight anion substitution as a promising strategy for optimizing polyanionic frameworks toward high-performance sodium-ion batteries.

Niobium-based phosphates have the advantages of high stability and environmental protection and have good application prospects in sodium-ion batteries. The pure phase of Na(NbO 2 ) 2 PO 4 (NNP) powder was successfully synthesized by different methods in this work, and the materials were characterized via XRD, XPS, SEM, and electrochemical methods. At the current density of 100 mA g −1 , the discharge-specific capacity of NNP is 521.8 mAh g −1 in the first cycle and remains at 462.4 mAh g −1 after 200 cycles, indicating that it has good cycling stability. The kinetic results obtained from cyclic voltammetry (CV) show the pseudo-capacitance contribution accounts for a large percentage of the capacity. The charge transfer resistance of NNP is 260.3 Ω, which is significantly smaller than the others derived from electrochemical impedance spectroscopy (EIS). These pointed to the advantages of NNP in anode material for SIBs.
