The Development and characterization of a new Solid Electrolyte for Sodium Battery

Abstract

This project was focused on the development of sodium titanogallate as a potential solid-state electrolyte for the development of solid-state battery technologies. The component materials comprising of sodium carbonate, gallium oxide, titanium oxide and acetone were obtained according to required standards and purity levels, and prepared following specified procedure. The materials were then weighed according the following the stoichiometric ratio, mixed with acetone acting to ensure a homogenous mixture, and heated using a box and tube furnace for temperatures ranging from 800 °C to 1350 °C for periods of 2 – 20 hours. Stoichiometric ratios of x = 0.00, x = 0.10, x =0.20 and x = 0.30 were used with the desired product formed with x = 0.20 and at 1200 °C. The products formed were analyzed using an x-ray diffraction Bruker D phase analysis device with Diffrac V3.1 software and results were visualized using a computer for analysis and interpretation. From the results of the analysis, with product formed was similar to previous researches carried out and exhibiting conductivity properties and structural features favourable for use as a solid electrolyte for solid state batteries.
