Abstract:
Highly dispersed oxides MgO, Al2O3, and MgO-Al2O3 were synthesized via an aerogel approach and used as a heterogeneous dopant for the preparation of solid electrolyte composites based on sodium nitrite. The oxides possess a developed surface area of 300–400 m2/g. The effects of the oxide content in the composition of prepared composite materials on their textural properties and phase composition were studied using X-ray diffraction analysis and low-temperature nitrogen adsorption. A mechanism for filling pores of an ionic salt during the formation of a composite was proposed. The introduction of 30–80 mol% of highly dispersed aerogel oxides was found to increase the ionic conductivity of the composites by 3 orders of magnitude. Thus, the ionic conductivity values for pure NaNO2 and the composite solid electrolytes at 200 °C were 1.8 × 10−6 and ∼6 × 10−3 S/cm, respectively. The highest ionic conductivity value of 6.45 × 10−3 S/cm was obtained for the composite sample containing 80 mol% of MgO.
