This study investigates the time-dependent degradation mechanisms observed in sodium-beta alumina solid electrolytes, particularly focusing on the slow crack propagation associated with Mode I failure. The objective is to understand the conditions under which cracks develop and propagate in these materials, particularly in the context of sodium/sulfur cell applications. Employing experimental methods that include current density testing on solid electrolyte samples, we identify a critical current density threshold below which slow crack growth is inhibited. Results indicate that degradation is intricately linked to operational current densities, and a specifically defined threshold plays a crucial role in the stability of the electrolytes during use. These findings contribute to the understanding of performance limitations in sodium-beta alumina solid electrolytes and provide insights for improving their durability in electrochemical applications.
