He is a chemist and group leader of the Advanced Electrolyte Research Group within the Electrochemical Energy Storage theme at Argonne National Laboratory. He has more than 20 years of organic/polymer chemistry research experience in the battery area. After receiving his doctorate in 2000, he joined Professor Robert West’s group at the University of Wisconsin-Madison as a research associate then a research scientist developing a portfolio of siloxane-based advanced electrolyte technologies for lithium-ion batteries for medical applications. At Quallion, LLC (now EnerSys), he led research and development (R&D) activities regarding a high energy density lithium-ion battery project and a solid polymer electrolyte for lithium monofluoride cells. In 2007, he joined Argonne setting up electrolyte synthesis labs and building a team comprising scientists with strong organic chemistry backgrounds focusing on advanced electrolyte research for lithium-ion chemistries and beyond, including high-voltage electrolytes, functional electrolyte additives, polymer binders, fluorinated ether electrolytes for lithium sulfur batteries, organic catholytes and anolytes for non-aqueous redox flow batteries, and non-Grignard magnesium-ion electrolytes. He won three R&D 100 Awards for advanced silicon-based electrolytes, redox shuttle additives for overcharge protection and a fluorinated electrolyte for 5-V lithium-ion chemistries. He published more than 120 publications in peer-reviewed journals and filed more than 50 patents/applications in the field of electrochemical energy storage.
He received his bachelor’s degree in chemistry in 1969 from the University of Wisconsin-Madison and a doctorate degree in Theoretical Chemistry in 1973 from Carnegie Mellon University. He was a fellow at Battelle Memorial Institute from 1973 to 1976 before joining Argonne National Laboratory. His research focuses on computational chemistry, including the development of new quantum chemical methods and the application of computational methods to problems in materials science and chemistry with catalysis, batteries, and carbon materials. He developed the series of quantum chemical methods referred to as Gaussian-n theory, which have been widely used for the accurate calculation of enthalpies of formation, ionization potentials, and electron affinities of molecules. His recent computational studies focused on the design of new electrolytes and electrolyte additives for lithium-ion batteries, modeling of anode materials for lithium-ion batteries, the understanding of charge and discharge chemistries in Li-O2batteries, catalytic reaction mechanisms of supported sub-nanometer clusters, and biomass conversion reaction mechanisms. He has over 450 publications and a member of the Joint Center for Energy Storage Research (JCESR).
