He is currently a senior chemist and group leader at Argonne National Laboratory specializing in the testing and post-test analysis of cells and complete battery systems with over 34 years of experience. He is known worldwide for his work in battery testing and life modeling. He has a bachelor’s in chemistry from Brown University and a doctorate in inorganic chemistry from University of Chicago. He is active in the battery materials and testing fields and has more than 120 publications and eight patents. He received an IR-100 Award in 1987 for a micro-membrane sensor to measure sodium-ion concentrations at elevated temperature. He participated in the creation of international recommended practices (one step before a standard) in battery testing. His work in battery life estimation led to the creation of software, which became the recognized standard for life estimation for battery development projects funded by U.S. Advanced Battery Consortium and the U.S. Department of Energy. In 2011, he established the post-test facility for the elucidation of the physical and chemical changes that cause battery performance decline.
He is a chemical engineer at Argonne National Laboratory with specializations in process analysis and modeling, and experimental validation of breadboard reactor systems. His interests include the design and technoeconomic analysis of lithium-ion batteries and production process of these batteries and their supply chain. He is responsible for the continuing development of BatPaC, a spreadsheet tool used for the design of lithium ion batteries and to estimate their cost. He is active in the analysis of vehicle batteries and production processes. He has conducted extensive analytical and experimental studies on the development of portable and distributed hydrogen production processes. These studies include the development of catalysts, reactor designs for the conversion of liquid and gaseous fuels to hydrogen, breadboard demonstrations, hydrogen concentrators, along with modeling studies of fuel cell systems, hydrogen production processes, and materials used in the production of lithium-ion batteries.
