Scott Barnett

Professor, Materials Science and Engineering, Northwestern University


Scott A. Barnett is a Professor in the Materials Science and Engineering department at Northwestern University. After receiving his Ph.D. in Metallurgy from the University of Illinois at Urbana-Champaign in 1982, he held postdoctoral appointments at the University of Illinois and Linkøping University (Sweden).

He took his present position at Northwestern in 1986. He has worked on ion-assisted deposition of semiconductor and ceramic thin films and coatings, and developed ultra-hard nitride nano-layered coatings. His research utilizes physical vapor and colloidal deposition methods for producing ceramic materials with energy applications, including Li-ion battery electrodes, solid oxide fuel cells (SOFCs), and regenerative solid oxide cells (ReSOCs).

He has worked on three-dimensional tomography of electrode microstructure for understanding electrochemical processes and degradation phenomena, SOFC operation with hydrocarbon fuels, and development of materials for intermediate temperature SOFCs.

He is also currently working on developing pressurized intermediate-temperature ReSOCs for achieving electricity storage with high round-trip efficiency.

3D Tomographic Measurements And Simulations Of Li-Ion Battery Positive Electrodes

This talk reviews the use of focused ion beam – scanning electron microscopy (FIB-SEM) and transmission X-ray microscopy (TXM) to obtain three-dimensional tomographic images of commercial lithium-ion battery electrodes such as LiFePO4, LiCoO2, and LiCoO2/Li(Ni1/3Mn1/3Co1/3)O2 composite.  After briefly reviewing the measurement techniques, the structural results are described, including imaging of both oxide and carbon phases. …
