报告摘要:

Energy storage is the absent enabler to facilitate the proliferation of renewable-but-intermittent solar and wind energy.There are two primary metrics for stationary storage: cost and cycling life, where the latter also pertains to the cost, indeed.It is, thus, a must to rely on earth-abundant elements, which rules out lithium-based devices for the storage purposes as lithium is rare and its supply is geopolitically challenged.This warrants attention for alternative batteries.At Oregon State University, we focus on pushing the boundaries of redox intercalation chemistry via carbon-based materials for sustainable energy storage solutions.We investigate structure-property correlations as design principles for electrodes in emerging redox chemistries, including sodium-ion batteries (NIBs), potassium-ion batteries (KIBs), dual-ion batteries (DIBs), and recently hydronium-ion batteries (HIBs).The electrode materials we currently study include non-graphitic carbon, such as hard carbon and soft carbon, and crystalline organic solids, including polycyclic aromatic hydrocarbons (PAHs).

报告人简介:Dr. Xiulei (David) Ji received his Ph.D. in Materials Chemistry under the guidance of Prof. Linda F. Nazar in the University of Waterloo, 2009.During 2010-2012, he was a NSERC Postdoctoral Fellow in Prof. Galen D. Stucky’s group in the University of California, Santa Barbara.He has been an Assistant Professor (promoted to Associate Professor with tenure from Sep. 2017) of chemistry at Oregon State University since 2012. His primal research interest is to elucidate the basic structure-charge storage correlation for carbon-based materials, including organic solids.He has published 73 articles, in leading journals, including Nature Materials, Nature Energy, Nature Chemistry, J. Am. Chem. Soc., Angew. Chem. Int. Ed., with total citations over 8300 times (Google Scholar).His honors include 2016 NSF CAREER Award, and NSERC Innovation Challenge Award of 2010.
