We are interested in the tailored synthesis of new materials at multiple length scales. At the molecular scale, the physical properties of materials are largely dependent on the stoichiometry and stable structures that can be formed. In addition, nano-scale topographies and geometries can dramatically influence material performance. We investigate hierarchical approaches to simultaneously design materials at the molecular, nanometer, and micrometer length scales. In applications such as lithium-ion battery electrodes, the active materials must be assembled as particles within a composite matrix. We are investigating general strategies to control the interactions between particles to form ordered assemblies.
Our current areas of focus in our lab are 1) the synthesis of particles of controlled size, shape, and composition for use in structured particle assemblies, 2) flowing electrochemical systems with solid electroactive materials including flow batteries, and 3) characterizing and understanding electrode microstructure in particular for thick battery electrodes.
