“…The NASICON structure of Na 1+ x Zr 2 Si x P 3‑ x O 12 (0 ≤ x ≤ 3) is the most widely investigated inorganic solid electrolyte. ,− Its crystal structure is a three-dimensional (3D) framework structure consisting of ZrO 6 octahedra connected with PO 4 or SiO 4 tetrahedra with covertexes, where sodium ions fill the interstices of the 3D framework and the interstitial connections constitute a 3D isotropic diffusion channel for sodium ions, which results in a high ionic conductivity. − The most common approach to improve the ionic conductivity of the inorganic ceramic electrolyte is doping. A large amount of research work has been published on cation doping occupying the Zr 4+ site, such as Ca 2+ , , Al 3+ , , Sc 3+ , Mg 2+ , , Zn 2+ , etc. Doping heterogeneous elements with a radius similar to that of Zr 4+ at the Zr site can regulate the transport properties of Na + by changing the Na + concentration and the local structure of the crystal.…”

Solid-state Na-CO2 batteries are a kind of energy storage devices that can immobilize and convert CO2. They have the advantages of both solid-state batteries and metal–air batteries. High-performance solid electrolyte and electrode materials are important for improving the performance of solid-state Na-CO2 batteries. In this work, we investigate the influence of fluorine doping on the structure and ionic conductivity of Na3Zr2Si2PO12 (NZSP). An ionic conductive solid electrolyte membrane was prepared by compositing the inorganic solid electrolyte Na2.7Zr2Si2PO11.7F0.3 (NZSPF3) with poly(vinylidene fluoride)-co-hexafluoropropylene (PVDF-HFP). It shows an ionic conductivity of up to 2.17 × 10–4 S cm–1 at room temperature, a high sodium ionic transfer number of ∼0.70, a broad electrochemical window of ∼5.18 V, and better mechanical strength. Furthermore, we studied the Na15Sn4/Na composite foil with the ability to inhibit dendrite as the anode for solid-state Na-CO2 batteries. Through density functional theory (DFT) calculations, the Na15Sn4 particle has been verified with a strong sodiophilic property, which reduces the nucleation barrier during the deposition process, leading to a lower overpotential. The symmetric cell assembled with the composite solid-state electrolyte NZSPF3-PVDF-HFP and Na15Sn4/Na composite anode can inhibit the growth of Na dendrites effectively and maintain the stability of the whole cell structure. Solid-state Na-CO2 batteries assembled with Ru-carbon nanotube (Ru-CNTs) as cathode catalysts exhibit a high discharge capacity of 6371.8 mAh g–1 at 200 mA g–1, excellent cycling stability for 1100 h, and good rate performance. This work provides a promising strategy for designing high-performance solid-state Na-CO2 batteries.
