TITLE: Properties of Thin Film Materials for Rechargeable Lithium Batteries

SPEAKER: Dr. Nancy J. Dudney,

TIME: Thursday Feb. 9, 2006 at 4:00 PM

PLACE: George P. Williams, Jr. Lecture Hall, (Olin 101)

About fifteen years ago, John Bates and Nancy Dudney initiated a DOE sponsored program to explore the fabrication of a solid-state thin-film rechargeable microbattery which could be integrated with electronic circuits and devices. Today the batteries are being commercialized, and the thin-film solid electrolyte, first synthesized at ORNL, is widely recognized for its outstanding electrochemical properties. Along the way, a number of fascinating scientific issues have been investigated. Because of the simple geometry, the thin film battery is a powerful tool for study of the kinetics and thermodynamics of the lithium intercalation reactions in crystalline and nanocrystalline transition metal oxides. Examples of this work will be highlighted. As time permits, additional topics concerning the synthesis and properties of the thin film materials will be presented, including: lithium transport in glassy electrolytes and the control of the composition and microstructure of ceramic films deposited by sputtering processes.
