Justin Connell

Materials Scientist


Justin Connell is a Materials Scientist and manager of the Electrochemical Discovery Laboratory, a collaborative research facility established by the Joint Center for Energy Storage Research at Argonne. He is also a member of the Consortium for Advanced Science and Engineering affiliated with the Pritzker School of Molecular Engineering at the University of Chicago. His current research interests focus on utilizing a combination of vacuum synthesis, electrochemical analysis and spectroscopic tools to understand the interfacial (electro)chemical processes that govern the stability and reversibility of anode and cathode materials for Li-ion and beyond Li-ion battery systems, as well as the reactivity of such materials at interfaces with solid electrolytes for all-solid-state batteries
