My research project goal is to produce a glassy solid electrolyte (GSE) that is stable and competitive with currently available liquid-based electrolytes. These GSEs in next-generation batteries present a safer, higher-performance alternative to liquid electrolytes, which can then be used in demanding environments, including vehicular and space technologies. The project’s initial scope focused on determining how to best design a GSE for bulk processing, which included developing a method to characterize the thin film drawability of GSEs utilizing crystallization and viscosity models. Once the metrics for drawability were determined, GSE compositions were explored to synthesize a viable candidate that met the drawability metric without compromising the ionic conductivity and stability of the GSE. Continuous efforts have been made to further understand the structure of the produced GSEs and their relationship to beneficial properties, focusing on spectroscopic, electrochemical, and thermal characterization methods. Key structural units have been identified and are being iteratively targeted in candidate GSEs to refine their performance further.
