The Role of Sintering Temperature and Dual Metal Substitutions (Al, Ti) in the Development of NASICON-Structured Electrolyte.

The aim of this study is to synthesize LiAlTiSn(PO) sodium super ion conductor (NASICON) -based ceramic solid electrolyte and to study the effect of dual metal substitution on the electrical and structural properties of the electrolyte. The performance of the electrolyte is analyzed based on the sintering temperature (550 to 950 °C) as well as the composition. The trend of XRD results reveals the presence of impurities in the sample, and from Rietveld Refinement, the purest sample is achieved at a sintering temperature of 950 °C and when x = 0.
