The structure of NASICON-type compounds, Nai+xScxTi2_z(P04)3 (0 < x < 2), and the dynamics of Na have been investigated by Na NMR spectroscopy. It was found that the Na ID and 2D MQMAS spectra depend on the Na concentration, suggesting strongly that the Na ions are distributed between two crystallographically nonequivalent sites, one is a special position with axial symmetry, and the other a po...

The title compound, rubidium ditin(IV) tris-(phosphate), RbSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates and crystallizes in the space group R[Formula: see text]. The structure is composed of PO(4) tetra-hedra (1 symmetry) and two slightly distorted SnO(6) octa-hedra, both with 3. symmetry, which are inter-linked through corner-sharing O atoms to form a (3) (∞)[Sn(2)(PO(4))(...

Owing to the 3D open framework, excellent structural stability, and high ionic conductivity, NASICON-type compounds are extensively employed as promising cathode materials for sodium-ion batteries (SIBs). Being one of representative compounds, Na3V2(PO4)3 delivers theoretical capacity with an operating voltage exceeding 3.3 V, enabling it be a good candidate SIBs. Unfortunately, suffers from lo...

Na super ionic CONductor (NASICON), Na1+xZr2SixP3–xO12, is an excellent solid-state electrolyte on account of its high sodium-ion conductivity, which can be further enhanced through chemical doping. However, the underlying sodium diffusion mechanism and how it affected by doping are not fully understood. This, in part, stems from ambiguity between reported average structure models, where there ...

We successfully demonstrated the applicability of microcontact impedance spectroscopy (MC IS) on Li conducting solid electrolytes and measured the Li bulk conductivity (sb) of LiTi2(PO4)3 (LTP) and Li1+xAlxTi2 x(PO4)3 (LATP) single crystals independent of microstructural effects (e.g., grain boundaries, pores, and density). The crystals had a size of about 100 mm in each direction and crystalli...

All-solid-state lithium batteries are a promising alternative to commercially available lithium-ion due their ability achieve high energy density, safety, and compactness. Electrolytes key components of all-solid-state batteries, as they crucial in determining the batteries’ efficiency. Herein, structure LiM2(PO4)3 (M = Ti, Ge, Zr) migration mechanisms introduced well different synthetic routes...

Present address: Xiao-Liang Wang, Seeo, Inc., 3906 Trust Way, Hayward, CA 94545, USA The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-L...

In this work, a planar solid-state potentiometric CO2 sensor for medical applications of the type CO2, O2, Au, Li2CO3-BaCO3 | Nasicon | Na2Ti6O13-TiO2, Au, O2, CO2 was developed in thick-film technology. Due to an integrated screen-printed platinum heater on the rear side, the sensor can be applied without changing its working temperature of 525°C in the main flow of the respiratory air of an i...
