NASICON- (Na superionic conductor-) based solid-state electrolytes (SSEs) are believed to be attracting candidates for sodium batteries due their high ionic conductivity and prospectively reliable stability. However, the poor interface compatibility formation of Na dendrites inhibit practical application. Herein, we directly observed propagation through NASICON-based 3.1 Zr 2 Si 2.1 P 0.9 O 12 ...

The arsenate(V) NaTi2[AsO4]3 has been synthesized by a solid-state reaction route using a salt flux. Its structure has been solved and refined from single-crystal X-ray data: NASICON-type, R3̄c, a = 8.8057(5), c = 22.2406(15) Å, Z = 6, wR(F2) = 0.0617 for 576 unique reflections and 30 variables. The NaTi2[AsO4]3 structure consists of a three-dimensional framework of corner-sharing AsO4 tetrahedr...

A simple and practicable evaporation-induced self-assembly (EISA) method is introduced for the first time to prepare nanosized solid electrolyte Li1.4Al0.4Ti1.6(PO4)3 (LATP) for all-solid-state lithium-ion batteries. A pure Na+ super ion conductor (NASICON) phase is confirmed by X-ray diffraction (XRD) analysis, and its primary particle size is down to 70 nm by optimizing evaporation rate of th...

The optimal sintering conditions for LiZr 2 (PO 4 ) 3 , a NASICON-type solid electrolyte with high conductivity, were explored. It was also found that these optimum could be efficiently discovered by using Bayesian optimisation.

We elucidate the complex thermodynamics of sodium (Na) intercalation into super-ionic conductor (NaSICON)-type electrode, Na x V 2 (PO 4 ) 3 , for promising Na-ion batteries with high-power density.
