2013 Nelson G 1x2









          Dr. Nelson received a NSF grant in the amount of $202,413 for his collaborative research effort between the University of Alabama in Huntsville and Texas A&M University based on the central hypothesis that mesoscale mechanical changes in Sn-intermetallic anodes will initially increase battery capacity by increasing active material accessibility from particle fracture and size reduction. These initial improvements are expected to be followed by segregation of active and inactive materials during continued cycling, leading to long term capacity fade. The investigations will include 3D microstructural imaging with x-ray nanotomography (UAH), computational modeling of mechanical-electrochemical interactions and microstructural damage (TAMU), and electrochemical measurements and computational modeling to assess the performance effects of microstructure (TAMU, UAH). Through a combination of experimental and computational efforts the proposed research will provide critical insight into the mesoscale science of transport, reaction, and mechanics in high-performance battery electrodes.


          Dr. George Nelson was appointed Assistant Professor in the Department of Mechanical and Aerospace Engineering at UAH in 2012. He received his BS, MS, and PhD degrees in Mechanical Engineering from the Georgia Institute of Technology in 2003, 2006, and 2009, respectively. He served as Assistant Research Professor at the University of Connecticut from 2009-2012. His general research interests include transport phenomena, energy storage and conversion devices, sustainable energy systems, and multi-scale modeling and analysis.
