Bio
Zhijia Du is a R&D staff in Energy & Transportation Science Division at Oak Ridge National Laboratory (ORNL). He earned his bachelor in Materials Science and Engineering from Beihang University in Beijing, 2008, and PhD in Materials Physics and Chemistry from Beihang University as well in 2013 with solid training in electrochemistry and materials science.
He was awarded the Izaak Walton Killam Postdoctoral Fellowship at Dalhousie University from 2013 to 2015, working with Prof Richard Dunlap and Prof Mark Obrovac. His work at Dal was the research and development of Si alloys for Li-ion battery and tin for sodium ion battery. Then he joined the Roll-to-Roll Manufacturing Group at ORNL in 2015. He continues working in the area of Li-ion battery and his current projects includes VOC exempt formulation of battery coatings, scaling-up of aqueous electrode processing, high speed UV/EB processing of battery electrodes, etc.
