Abstract

Solid electrolytes for secondary batteries offer advantages over liquid ones, enhancing application range and scalability. While oxide-based solid electrolytes are actively researched for all-solid-state batteries, studies on the atmospheric stability of lithium borosilicate (LBS) glass are limited. Notably, LBS glass green sheets show significant changes in mechanical properties under varying humidity. This study investigates the aging of LBS glass materials, both as powder and green sheets, in controlled humid environments. Analysis using thermal gravimetric analysis-differential thermal analysis (TG-DTA), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR) revealed that moisture evaporation and crystal formation occur over time. Both forms reacted with atmospheric H₂O, forming new crystal structures, especially under high humidity. In conclusion, LBS glass undergoes structural and chemical changes due to humidity and time, highlighting the importance of considering environmental conditions in practical applications.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
