Fast ion conducting glasses have long been considered as alternatives to flammable liquid electrolytes in Li batteries. However, to date, there has never been before the unique combination of required electrochemical properties in any one such glass for its use as a solid electrolyte with the equally important requirements of viscoelastic behavior to form them into thin films suitable for high ion conductivity separators. In this first ever report of thin film fast ion conducting glasses, we will summarize our efforts to produce thin films of Na ion conducting glasses and test in them in symmetric, asymmetric, and full cells.

Steve W. Martin received his B.S. in Chemistry from Capital University in 1980 and his Ph.D. in Physical Chemistry from Purdue University in 1986. From Purdue, he directly joined the faculty of Materials Science & Engineering in 1986 and was promoted to Associate Professor in 1991 and Full Professor in 1996. He has since been promoted to the ranks of University Professor in 2006 and to the rank of Anson Marston Distinguished Professor in Engineering in 2009. He has been awarded the George W. Morey Award in Glass Science from the Glass and Optical Materials Division of the American Ceramic Society, where he is also a named Fellow of the society, and adwarded the American Ceramic Society Ceramic Education Council Outstanding Educator Awaed. He has been a visiting professor on 10 different occasions at universities around the world. His core research specialization is the preparation, characterization and study of ionically conducting glasses for all solid state lithium and sodium batteries. His broader research interests include glass and amorphous materials, solid electrolytes for batteries and fuel cells, optical materials and fibers and the characterization of materials.
