Abstract

Language:

This study investigates the microstructure, defects, and sodium transport mechanisms in sodium beta-alumina solid electrolytes, which are critical for advancing energy storage technologies. The main objective is to understand how microstructural features, such as grain boundaries and defect density, affect ionic conductivity. A combination of experimental techniques including high-resolution imaging and ion transport measurements were employed to characterize the microstructural properties of the materials. By analyzing the effects of annealing temperatures on defect behavior, a notable decrease in fault density was observed around 1500 °C, indicating potential pathways for enhancing ionic conductivity. Moreover, the presence of blocking grain boundaries was confirmed, contributing to partial ionic blocking effects during sodium transport. These results provide essential insights into optimizing sodium beta-alumina as a solid electrolyte, presenting implications for its application in solid-state batteries. The findings serve as a foundation for further explorations into material enhancements and performance improvements in next-generation energy storage systems.
