Physical Chemistry of Materials

This group investigates the fundamental properties of electrochemically and catalytically active materials, as well as their fabrication into functional and practical systems.  Many studies lead to laboratory prototypes for electrical energy storage, catalytic reactors and separation systems.  Other programs seek a basic understanding of atomic level mechanisms, materials stability, and interfaces. 


Mechanically Robust, Sodium-Ion Conducting Membranes for Nonaqueous Redox Flow Batteries

Sodium-based batteries are promising for grid-storage applications because of significantly lower cost compared to lithium-based systems. The advancement of solid-state and redox-flow sodium-ion...

A Novel Electrolyte Salt Additive for Lithium-Ion Batteries with Voltages Greater than 4.7 V

Lithium bis(2-methyl-2-fluoromalonato)borate (LiBMFMB), as an additive for LiNi0.5Mn1.5O4, exhibits improved efficiencies and cycling stability. Cyclic voltammograms indicate the cells with additive...

Probing Multiscale Transport and Inhomogeneity in a Lithium-Ion Pouch Cell Using In Situ Neutron Methods

We demonstrate the lithiation process in graphitic anodes using in situ neutron radiography and diffraction in a single-layer pouch cell. The variation in neutron absorption contrast in graphite...
