Research Overview

Our research emphasizes the development of novel thin film materials and structures for several applications.  Electrochemical energy storage in reversible lithium ion and lithium metal batteries is a primary interest.  We are developing approaches to improve the stability (e.g. cycle life) and power performance in lithium batteries. For lithium metal batteries, for example, we are studying the stabilization of lithium metal anodes for safe, reversible cycling where the formation of dendritic morphologies is suppressed. In lithium ion batteries, thin coating layers and/or surface modifications are used to dramatically alter reaction kinetics. We have expertise in many thin film synthesis techniques-both vacuum and solution based. In particular, we exploit the exceptional compositional control and conformality of initiated chemical vapor deposition (iCVD) for the synthesis of polymeric thin films. The fundamentals of this technique are studies such that new capabilities can be developed.

We are also interested in redox flow batteries for grid level energy storage applications.  We are utilizing our expertise in solid electrolyte characterization to develop new flow battery concepts.  Replacing the porous membrane separating the two charge storage solutions with a liquid-impermeable solid electrolyte provides new opportunities that we are exploring.
